struct AssetPackManifestA manifest of asset packs that are available to download.
assetPack(id: string): (AssetPack) | nullfunc assetPack(withID id: String) -> AssetPack?Returns the asset pack in this manifest with the given ID. - Parameter id: The asset pack’s ID. - Returns: The asset pack, if it could be found in this manifest; otherwise, `nil`.
localizedAssetPacksFor(language: _Foundation_Locale_Language): Array<AssetPack>func localizedAssetPacks(for language: Locale.Language) -> Set<AssetPack>Returns the subset of asset packs in this manifest that are available to download and that best match the specified language. Depending on which languages are available, the returned asset packs’ respective languages may not exactly match the specified language. - Parameter language: The language. - Returns: The localized asset packs.
get localizedAssetPacks(): Array<AssetPack>var localizedAssetPacks: Set<AssetPack> { get }The subset of asset packs in this manifest that best match the current preferred languages.
get assetPacks(): Array<AssetPack>let assetPacks: Set<AssetPack>The asset packs in this manifest that are available to download.
static initContentsOfAppGroupID(url: string, appGroupID: string): AssetPackManifestinit(contentsOf url: URL, appGroupID: String) throwsCreates a manifest in memory given a URL to the manifest’s representation as a JSON file on disk. - Parameters: - url: A URL to a local JSON file. - appGroupID: The ID of the app group in which to store unmanaged asset packs that are downloaded from this manifest.
get description(): stringvar description: String { get }A textual representation of this instance. Calling this property directly is discouraged. Instead, convert an instance of any type to a string by using the `String(describing:)` initializer. This initializer works with any type, and uses the custom `description` property for types that conform to `CustomStringConvertible`: struct Point: CustomStringConvertible { let x: Int, y: Int var description: String { return "(\(x), \(y))" } } let p = Point(x: 21, y: 30) let s = String(describing: p) print(s) // Prints "(21, 30)" The conversion of `p` to a string in the assignment to `s` uses the `Point` type's `description` property.
allDownloads(contentRequest?: (BAContentRequest) | null): Array<BADownload>func allDownloads(for contentRequest: BAContentRequest?) -> Set<BADownload>Creates download objects for every applicable asset pack in this manifest, which can be scheduled with the download manager. - Parameter contentRequest: The content request for the current extension invocation. Pass `nil` if when calling this method in your main app. - Returns: A collection of download objects.
get primaryLanguage(): (_Foundation_Locale_Language) | nullvar primaryLanguage: Locale.Language? { get }The app’s primary language as configured in App Store Connect. If no available localized asset packs match the current preferred languages, then the system falls back on the app’s primary language.
get resolvedLanguage(): (_Foundation_Locale_Language) | nullvar resolvedLanguage: Locale.Language? { get }The language that best matches current preferences and for which a localized asset pack is available locally. The preferred languages set in Settings or System Settings inform the choice of resolved language, respecting any language that your app sets manually by setting ``AssetPackManager/resolvedLanguage``. This property may be `nil` if no localized asset packs are available. If a person using the device recently changed their preferred language or if this manifest is outdated, then this property’s value may be out of sync with the set of asset packs that are available locally.
get availableLanguages(): Array<_Foundation_Locale_Language>var availableLanguages: [Locale.Language] { get }The languages for which asset packs in this manifest are localized.
static initFromAppGroupID(data: ArrayBuffer, appGroupID: string): AssetPackManifestinit(from data: Data, appGroupID: String) throwsCreates a manifest in memory given JSON-encoded data. - Parameters: - data: JSON-encoded data. - appGroupID: The ID of the app group in which to store unmanaged asset packs that are downloaded from this manifest.
static initFromConfiguration(decoder: SDKHandle, configuration: AssetPackManifest_DecodingConfiguration): AssetPackManifestinit(from decoder: any Decoder, configuration: AssetPackManifest.DecodingConfiguration) throwsCreates a new instance by retrieving the instance's data from the specified decoder with help from the provided configuration. - Parameters: - decoder: The decoder to read data from. - configuration: A decoding configuration instance that provides additional information necessary for decoding.
