Some of the asset types in a catalog work only with selected Apple platforms. ### Content Types The type of content represented by a folder is encoded in the extension for the name of the folder. For example, a folder named`PosingLlamas.imageset` has a type of`imageset`. Table 5-1 lists the content types, folder name extension, and a brief description of each type.

Figure 2-1Asset catalog folders The Asset catalog folder contains all the folders and files for one asset catalog. Group folders contain asset folders and other group folders. Asset folders contain the files for an individual asset. Each folder can contain a`.json` file encoding the attributes for the catalog, group, or asset in that folder. For more information on the`.json` file, see Contents.json File and Table 5-2. ### Folder Names The name and the type of an asset catalog item are encoded in the folder name. Each folder name contains the name of the catalog or asset, followed by a period (.), and then a type identifier: `. ` Groups do not have a type identifier: ` ` ### Unique Asset Names For any target in an Xcode project, the fully qualified name of an asset must be unique across all the asset catalogs and across all asset types. For example, it is an error to have an image set folder in one asset catalog called`Llama.imageset` and an image set with the same name in the same catalog or in a different catalog that is part of the same target. Similarly, it is an error to have both an image set folder called`Llama.imageset` and an app icon folder called`Llama.appiconset` in the same catalog or in a different catalog that is part of the same target. The full name includes the name of any group or sprite atlas folders that are marked as providing a namespace. For example, if the group folder`mammals` contains an image set`Llama.imageset`, the fully qualified name of the image set is`mammals/Llama`. ### General Folder Structure The asset catalog folder is at the top level of the catalog. Inside the asset catalog folder is at least one asset folder. There may also be group folders. The general folder structure for an asset catalog is: `.xcassets` `. ` `Asset files` ` ` `Group contents` As an example, the folders in the catalog shown in Figure 2-1 are: `TestCatalog.xcassets` `Complication` `Data.dataset` ` ` `iOS AppIcon.appiconset` ` ` `Llamas` `Llamas at home.imageset` ` ` `Posing llamas.imageset` ` ` `Spot the Llama.imageset` ` ` `Sprites.spriteatlas` ` ` `Spark.imageset` ` ` <title>Asset Catalog Format Reference: Contents.json File</title> https://developer.apple.com/library/archive/documentation/Xcode/Reference/xcode_ref-Asset_Catalog_Format/Contents.html Asset Catalog Format Reference: Contents.json File " /> " /> " /> Asset Catalog Format Reference On This Page - .json Format - Tag Types - Slot Components ## Contents.json File `Contents.json` files encode the attributes for elements represented by folders in the hierarchy. Each folder can contain one`Contents.json` file that encodes the attributes for the asset or group it contains. For information on which folder types require the file, see Table 5-2. ### .json Format The information in a`Contents.json` file is represented by pairs of tags and values using standard`.json` format. The general structure of the file is: `" " : ` `" " : ` `…` `" " : ` The tag name is an attribute of the asset catalog or asset file. For example, the`filename` attribute is the filename for a specific image or icon. The value of the tag depends on the type of the tag. ### Tag Types Table 3-1 describes the tag types that`Contents.json` can contain. Type Value Format Array An array of items of the same type. `" " : [` `,` `,` `…` ` ` `]` Boolean A Boolean value of true or false. `" " : ` Dictionary A list of associations between keys and values. `" " : {` `" " :,` `…` `" " : ` `}` Enum A group of related values. `" " : " " ` Number A numerical value. `" " : ` String A string value. `" " : " "` Slot component A special type of enum. See Slot Components below. | Table 3-1`Contents.json` file tag types | | --- | For information on the tags and possible values for each type of folder, see the details for each type in the Type Reference. ### Slot Components A slot component is a special type of tag used to create an identifier for the elements in an asset type. The identifier is a combination of the values for each slot component tag for an element. The identifiers must be unique for elements in the same named asset type folder. Items in other named asset folders can use the same identifier. For example,`idiom`,`scale`,`subtype`,`screen-width`,`width-class`, and`height-class` are the slot component tags for the image set asset type. There can be only one combination of`"idiom": "universal"`,`"scale": "3x"`,`"subtype": ""`,`"screen-width": ""`,`"width-class": ""`,`"height-class": "regular"`, for the`mountain-llama` image. The same combination can be used for the`norwegian-blue-parrot` image.

Documentation Archive Developer Search Search Documentation Archive Technical Q&A QA1697 # Why doesn&`#39`;t my device load a file that loads fine in the Simulator? ## Q: Why doesn&`#39`;t my device load a file that loads fine in the Simulator? A: Why doesn&`#39`;t my device load a file that loads fine in the Simulator? Two things should be kept in mind when accessing files in application bundles using the Simulator versus a device. Case-sensitivity: iPhone OS uses a case-sensitive file system, unlike the Simulator which uses a case-insensitive file system by default. Make sure the case-sensitivity of resources accessed within code matches the filename case-sensitivity. For example, if our filename is "YourExampleImage.png": Good:`[UIImage imageNamed:@"YourExampleImage.png"]` Bad:`[UIImage imageNamed:@"YourExampleImage.PNG"]` Bad:`[UIImage imageNamed:@"yourexampleimage.png"]` Location: Methods that require a path should be accessed using the`-[pathForResource:ofType:inDirectory:]` method of`NSBundle`. They should not be accessed using a string representation of the filename. Listing 1 Accessing Default.png from within an application bundle. ``` UIImage *defaultImage = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"Default" ofType:@"png" inDirectory:nil]]; ``` --- #### Document Revision History New document that shows how to avoid issues where an app&`#39`;s resources load fine in the Simulator, but not on a device. | Date | Notes | | --- | --- | | 2010-06-01 |

Keep the SVG in the imageset with its manifest.

The reachable Books button passes "Books" to Image. The changed manifest references Open Book - Iconly Pro.svg, but that file is in Books.imageset while the manifest is in books.imageset. An image set requires its Contents.json, and the referenced file must be in that image set. This mismatch can prevent the Books icon from being packaged or resolved.

<title>Asset Catalog Format Reference: Format Overview</title> https://developer.apple.com/library/archive/documentation/Xcode/Reference/xcode_ref-Asset_Catalog_Format/index.html Asset Catalog Format Reference: Format Overview Asset Catalog Format Reference On This Page - Asset Catalog Contents - General Format ## Format Overview Asset catalogs simplify access to app resources by mapping between named assets and one or more files targeted for different device attributes. Attributes include device characteristics, size classes, on-demand resources, and type-specific information. The attributes are used to choose the best file for app slicing variants, and at runtime to choose the right image for the current screen orientation. For more information on asset catalogs, see Asset catalogs in Xcode Help. For more information on app slicing, see App Thinning (iOS, watchOS). ### Asset Catalog Contents The different kinds of elements in an asset catalog are shown in Figure 1-1. Figure 1-1Asset catalog elements The contents of an asset catalog include: Groups. A group can contain one or more assets and one or more groups. Assets. An asset is a set of files and the associated attributes for one named asset of a single type. Asset names are the developer-defined strings used to access the asset. Asset files are the resource or data files for a named asset. Attributes. An attribute is a characteristic of a group, asset, or asset file. Asset variations. An asset variation is a single sliced variant of one named asset that is based on the set of assigned attribute values. For more information on slicing, see Slicing (iOS). ### General Format The contents of an asset catalog, mentioned in the previous section, are organized into these parts: Folders. A folder can contain an asset and a group. The name of a folder containing an asset includes the name of the asset and the type of the asset. Group folder names do not have a type extension. The hierarchy of folders is used for the hierarchy of the asset catalog. JSON files. A`.json` file contains the attributes for an asset, a group of assets, or the asset catalog. Content files. A content file is a resource or data file for one variation of one asset. <title>Asset Catalog Format Reference: Types Overview</title> https://developer.apple.com/library/archive/documentation/Xcode/Reference/xcode_ref-Asset_Catalog_Format/AssetTypes.html Asset Catalog Format Reference: Types Overview Asset Catalog Format Reference On This Page - Content Types - Contents.json File - Platform Types ## Types Overview The folders in asset catalogs represent the overall asset catalog, groups of assets and other groups, and several different types of assets. Some of the asset types in a catalog work only with selected Apple platforms. ### Content Types The type of content represented by a folder is encoded in the extension for the name of the folder. For example, a folder named`PosingLlamas.imageset` has a type of`imageset`. Table 5-1 lists the content types, folder name extension, and a brief description of each type. Table 5-1Content types | Folder type | Extension | Description | | --- | --- | --- | | App Icon Type | `.appiconset` | The various sizes of the icon for an iOS or watchOS app. Children are`.png` files. | | AR Reference Image | `.arimageset` | An image file for an ARReferenceImage.

Each folder can contain one`Contents.json` file that encodes the attributes for the asset or group it contains. For information on which folder types require the file, see Table 5-2. ### .json Format The information in a`Contents.json` file is represented by pairs of tags and values using standard`.json` format. The general structure of the file is: `" " : ` `" " : ` `…` `" " : ` The tag name is an attribute of the asset catalog or asset file. For example, the`filename` attribute is the filename for a specific image or icon. The value of the tag depends on the type of the tag. ### Tag Types Table 3-1 describes the tag types that`Contents.json` can contain. Type Value Format Array An array of items of the same type. `" " : [` `,` `,` `…` ` ` `]` Boolean A Boolean value of true or false. `" " : ` Dictionary A list of associations between keys and values. `" " : {` `" " :,` `…` `" " : ` `}` Enum A group of related values. `" " : " " ` Number A numerical value. `" " : ` String A string value. `" " : " "` Slot component A special type of enum. See Slot Components below. | Table 3-1`Contents.json` file tag types | | --- | For information on the tags and possible values for each type of folder, see the details for each type in the Type Reference. ### Slot Components A slot component is a special type of tag used to create an identifier for the elements in an asset type. The identifier is a combination of the values for each slot component tag for an element. The identifiers must be unique for elements in the same named asset type folder. Items in other named asset folders can use the same identifier. For example,`idiom`,`scale`,`subtype`,`screen-width`,`width-class`, and`height-class` are the slot component tags for the image set asset type. There can be only one combination of`"idiom": "universal"`,`"scale": "3x"`,`"subtype": ""`,`"screen-width": ""`,`"width-class": ""`,`"height-class": "regular"`, for the`mountain-llama` image. The same combination can be used for the`norwegian-blue-parrot` image.

Figure 2-1Asset catalog folders The Asset catalog folder contains all the folders and files for one asset catalog. Group folders contain asset folders and other group folders. Asset folders contain the files for an individual asset. Each folder can contain a`.json` file encoding the attributes for the catalog, group, or asset in that folder. For more information on the`.json` file, see Contents.json File and Table 5-2. ### Folder Names The name and the type of an asset catalog item are encoded in the folder name. Each folder name contains the name of the catalog or asset, followed by a period (.), and then a type identifier: `. ` Groups do not have a type identifier: ` ` ### Unique Asset Names For any target in an Xcode project, the fully qualified name of an asset must be unique across all the asset catalogs and across all asset types. For example, it is an error to have an image set folder in one asset catalog called`Llama.imageset` and an image set with the same name in the same catalog or in a different catalog that is part of the same target. Similarly, it is an error to have both an image set folder called`Llama.imageset` and an app icon folder called`Llama.appiconset` in the same catalog or in a different catalog that is part of the same target. The full name includes the name of any group or sprite atlas folders that are marked as providing a namespace. For example, if the group folder`mammals` contains an image set`Llama.imageset`, the fully qualified name of the image set is`mammals/Llama`. ### General Folder Structure The asset catalog folder is at the top level of the catalog. Inside the asset catalog folder is at least one asset folder. There may also be group folders. The general folder structure for an asset catalog is: `.xcassets` `. ` `Asset files` ` ` `Group contents` As an example, the folders in the catalog shown in Figure 2-1 are: `TestCatalog.xcassets` `Complication` `Data.dataset` ` ` `iOS AppIcon.appiconset` ` ` `Llamas` `Llamas at home.imageset` ` ` `Posing llamas.imageset` ` ` `Spot the Llama.imageset` ` ` `Sprites.spriteatlas` ` ` `Spark.imageset` ` `

Keep the electronics asset manifest and SVG in the same imageset.

CircularFilterButton passes "Electronics" to Image, and the home screen renders this button for the Electronics category. The canonical manifest is under electronics.imageset, but its referenced SVG is under Electronics.imageset. The uppercase imageset has only Contents 2.json, not the required Contents.json. This case/path mismatch can leave the Electronics image unavailable.

Apple Xcode asset catalogs image set name case sensitive UIImage named asset catalog case sensitivity Contents.json

<title>init(named:) | Apple Developer Documentation</title> https://developer.apple.com/documentation/uikit/uiimage/init(named:) # init(named:) Creates an image object from the specified named asset. ``` init?(named name: String) ``` ## Parameters `name` The name of the image asset or file. ## Return Value An object containing an unconfigured version of the image, or `nil` if the method could not find the specified image. ## Discussion When searching the asset catalog, this method prefers an asset containing a symbol image over an asset with the same name containing a bitmap image. Because the system supports symbol images iOS 13 or later, you may include both types of assets in the same asset catalog. In iOS 12 or earlier, the system automatically chooses the bitmap image. You can’t use this method to load system symbol images; use the `init(systemName:)` method instead. This method checks the system caches for an image object with the name you specify, and returns the variant of that image that’s best suited for the main screen. If a matching image object isn’t in the cache, this method creates the image from an available asset catalog or loads the image from disk. The system may purge cached image data at any time to free up memory. Purging occurs only for unused images that are in the cache. In iOS 9 and later, this method is thread safe. ### Special Considerations If you intend to display an image only once and don’t want it added to the system’s cache, create it using the `imageWithContentsOfFile:` method instead. Keeping single-use images out of the system image cache can potentially improve the memory use characteristics of your app. --- Copyright © 2026 Apple Inc.

Each folder can contain one`Contents.json` file that encodes the attributes for the asset or group it contains. For information on which folder types require the file, see Table 5-2. ### .json Format The information in a`Contents.json` file is represented by pairs of tags and values using standard`.json` format. The general structure of the file is: `" " : ` `" " : ` `…` `" " : ` The tag name is an attribute of the asset catalog or asset file. For example, the`filename` attribute is the filename for a specific image or icon. The value of the tag depends on the type of the tag. ### Tag Types Table 3-1 describes the tag types that`Contents.json` can contain. Type Value Format Array An array of items of the same type. `" " : [` `,` `,` `…` ` ` `]` Boolean A Boolean value of true or false. `" " : ` Dictionary A list of associations between keys and values. `" " : {` `" " :,` `…` `" " : ` `}` Enum A group of related values. `" " : " " ` Number A numerical value. `" " : ` String A string value. `" " : " "` Slot component A special type of enum. See Slot Components below. | Table 3-1`Contents.json` file tag types | | --- | For information on the tags and possible values for each type of folder, see the details for each type in the Type Reference. ### Slot Components A slot component is a special type of tag used to create an identifier for the elements in an asset type. The identifier is a combination of the values for each slot component tag for an element. The identifiers must be unique for elements in the same named asset type folder. Items in other named asset folders can use the same identifier. For example,`idiom`,`scale`,`subtype`,`screen-width`,`width-class`, and`height-class` are the slot component tags for the image set asset type. There can be only one combination of`"idiom": "universal"`,`"scale": "3x"`,`"subtype": ""`,`"screen-width": ""`,`"width-class": ""`,`"height-class": "regular"`, for the`mountain-llama` image. The same combination can be used for the`norwegian-blue-parrot` image.

Some of the asset types in a catalog work only with selected Apple platforms. ### Content Types The type of content represented by a folder is encoded in the extension for the name of the folder. For example, a folder named`PosingLlamas.imageset` has a type of`imageset`. Table 5-1 lists the content types, folder name extension, and a brief description of each type.

<title>Technical Q&A QA1697: Why doesn&`#39`;t my device load a file that loads fine in the Simulator?</title> https://developer.apple.com/library/archive/qa/qa1697/_index.html Technical Q&A QA1697: Why doesn&`#39`;t my device load a file that loads fine in the Simulator? Documentation Archive Developer Search Search Documentation Archive Technical Q&A QA1697 # Why doesn&`#39`;t my device load a file that loads fine in the Simulator? ## Q: Why doesn&`#39`;t my device load a file that loads fine in the Simulator? A: Why doesn&`#39`;t my device load a file that loads fine in the Simulator? Two things should be kept in mind when accessing files in application bundles using the Simulator versus a device. Case-sensitivity: iPhone OS uses a case-sensitive file system, unlike the Simulator which uses a case-insensitive file system by default. Make sure the case-sensitivity of resources accessed within code matches the filename case-sensitivity. For example, if our filename is "YourExampleImage.png": Good:`[UIImage imageNamed:@"YourExampleImage.png"]` Bad:`[UIImage imageNamed:@"YourExampleImage.PNG"]` Bad:`[UIImage imageNamed:@"yourexampleimage.png"]` Location: Methods that require a path should be accessed using the`-[pathForResource:ofType:inDirectory:]` method of`NSBundle`. They should not be accessed using a string representation of the filename. Listing 1 Accessing Default.png from within an application bundle. ``` UIImage *defaultImage = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"Default" ofType:@"png" inDirectory:nil]]; ``` --- #### Document Revision History New document that shows how to avoid issues where an app&`#39`;s resources load fine in the Simulator, but not on a device. | Date | Notes | | --- | --- | | 2010-06-01 | <title>init(named:) | Apple Developer Documentation</title> https://developer.apple.com/documentation/uikit/uiimage/init(named:) # init(named:) Creates an image object from the specified named asset. ``` init?(named name: String) ``` ## Parameters `name` The name of the image asset or file. ## Return Value An object containing an unconfigured version of the image, or `nil` if the method could not find the specified image. ## Discussion When searching the asset catalog, this method prefers an asset containing a symbol image over an asset with the same name containing a bitmap image. Because the system supports symbol images iOS 13 or later, you may include both types of assets in the same asset catalog. In iOS 12 or earlier, the system automatically chooses the bitmap image. You can’t use this method to load system symbol images; use the `init(systemName:)` method instead. This method checks the system caches for an image object with the name you specify, and returns the variant of that image that’s best suited for the main screen. If a matching image object isn’t in the cache, this method creates the image from an available asset catalog or loads the image from disk. The system may purge cached image data at any time to free up memory. Purging occurs only for unused images that are in the cache. In iOS 9 and later, this method is thread safe. ### Special Considerations If you intend to display an image only once and don’t want it added to the system’s cache, create it using the `imageWithContentsOfFile:` method instead. Keeping single-use images out of the system image cache can potentially improve the memory use characteristics of your app. --- Copyright © 2026 Apple Inc.

Figure 2-1Asset catalog folders The Asset catalog folder contains all the folders and files for one asset catalog. Group folders contain asset folders and other group folders. Asset folders contain the files for an individual asset. Each folder can contain a`.json` file encoding the attributes for the catalog, group, or asset in that folder. For more information on the`.json` file, see Contents.json File and Table 5-2. ### Folder Names The name and the type of an asset catalog item are encoded in the folder name. Each folder name contains the name of the catalog or asset, followed by a period (.), and then a type identifier: `. ` Groups do not have a type identifier: ` ` ### Unique Asset Names For any target in an Xcode project, the fully qualified name of an asset must be unique across all the asset catalogs and across all asset types. For example, it is an error to have an image set folder in one asset catalog called`Llama.imageset` and an image set with the same name in the same catalog or in a different catalog that is part of the same target. Similarly, it is an error to have both an image set folder called`Llama.imageset` and an app icon folder called`Llama.appiconset` in the same catalog or in a different catalog that is part of the same target. The full name includes the name of any group or sprite atlas folders that are marked as providing a namespace. For example, if the group folder`mammals` contains an image set`Llama.imageset`, the fully qualified name of the image set is`mammals/Llama`. ### General Folder Structure The asset catalog folder is at the top level of the catalog. Inside the asset catalog folder is at least one asset folder. There may also be group folders. The general folder structure for an asset catalog is: `.xcassets` `. ` `Asset files` ` ` `Group contents` As an example, the folders in the catalog shown in Figure 2-1 are: `TestCatalog.xcassets` `Complication` `Data.dataset` ` ` `iOS AppIcon.appiconset` ` ` `Llamas` `Llamas at home.imageset` ` ` `Posing llamas.imageset` ` ` `Spot the Llama.imageset` ` ` `Sprites.spriteatlas` ` ` `Spark.imageset` ` ` <title>Asset Catalog Format Reference: Format Overview</title> https://developer.apple.com/library/archive/documentation/Xcode/Reference/xcode_ref-Asset_Catalog_Format/index.html Asset Catalog Format Reference: Format Overview Asset Catalog Format Reference On This Page - Asset Catalog Contents - General Format ## Format Overview Asset catalogs simplify access to app resources by mapping between named assets and one or more files targeted for different device attributes. Attributes include device characteristics, size classes, on-demand resources, and type-specific information. The attributes are used to choose the best file for app slicing variants, and at runtime to choose the right image for the current screen orientation. For more information on asset catalogs, see Asset catalogs in Xcode Help. For more information on app slicing, see App Thinning (iOS, watchOS). ### Asset Catalog Contents The different kinds of elements in an asset catalog are shown in Figure 1-1. Figure 1-1Asset catalog elements The contents of an asset catalog include: Groups. A group can contain one or more assets and one or more groups. Assets. An asset is a set of files and the associated attributes for one named asset of a single type. Asset names are the developer-defined strings used to access the asset. Asset files are the resource or data files for a named asset. Attributes. An attribute is a characteristic of a group, asset, or asset file. Asset variations. An asset variation is a single sliced variant of one named asset that is based on the set of assigned attribute values. For more information on slicing, see Slicing (iOS). ### General Format The contents of an asset catalog, mentioned in the previous section, are organized into these parts: Folders. A folder can contain an asset and a group. The name of a folder containing an asset includes the name of the asset and the type of the asset. Group folder names do not have a type extension. The hierarchy of folders is used for the hierarchy of the asset catalog. JSON files. A`.json` file contains the attributes for an asset, a group of assets, or the asset catalog. Content files. A content file is a resource or data file for one variation of one asset. <title>UIImage and Umlauts</title> https://developer.apple.com/forums/thread/44646 UIImage and Umlauts | Apple Developer Forums # UIImage and Umlauts Programming LanguagesSwiftSwift You’re now watching this thread.

JanGaehlerOP CreatedApr ’16 Replies3 Boosts0 Views485 Participants3 Hi, this code works fine with all files, but not if there is an umlaut in the filename. ``` `if (UIImage (named: imageName) !== nil) { categoryImage.image == UIImage(named: ""\\(self.category.name).png"" ) print(""\\(self.category.name).png"") } else { categoryImage.image == UIImage(named: ""missing"") print(""Missing: \\(self.category.name).png"") }` ``` Output (Umlaut): **Missing: Gemüse.png** But the file exists. Is there a problem with the encoding of the unicode filename? Or do i miss something? Boost Copy to clipboard Share this post Copied to Clipboard Replies3 Boosts0 Views485 Participants3 OOPerOP Apr ’16 As far as I tested, UIImage.init(named:) can handle filenames including umlauts properly. In your code, ``imageName`` is really exactly the same as ``""\\(self.category.name).png""``? Or the image file really exists in the app bundle? (Not just seen in the project.) 0comments 1 Copy to clipboard Share this post Copied to Clipboard Load moreAdd comment QuinceyMorrisOP Apr ’16 I agree with OOPer that there&`#39`;s something else going on here. Keep in mind that the iOS file system is case-sensitive. If the file is actually "gemüse.png", I don&`#39`;t think it will be found by this API. Also, I recommend that you don&`#39`;t include the ".png" extension in the name. The API will find the file without it (and the actual file may have a different extension anyway, because Xcode compresses some PNG files into a special format when you build your app). 0comments 1 Copy to clipboard Share this post Copied to Clipboard Load moreAdd comment JanGaehlerOP Apr ’16 Thank you both, yes imageName == self.category.name and wait …oh no …the Data comes out of an .csv file.

Keep the manifest with the School.imageset asset.

HomeView reaches the School filter and requests Image("School"). The valid manifest is under lowercase school.imageset, but its SVG is under uppercase School.imageset. School.imageset currently has only Contents 2.json, so it has no valid image-set manifest. On iOS, case-sensitive resource lookup can leave the School icon unavailable.

Suggested fix

the lowercase school asset set to the uppercase School asset set, so HomeView
can resolve the School icon on case-sensitive systems.
