I'm currently trying to use the new @UnionValue macro. From what I understood, it allows multiple types for a parameter. I created the following enum: @UnionValue enum IntentDuration { case int(Int) case duration(Measurement<UnitDuration>) } Then, I tried to use it in the following AppIntent: struct MyIntent: AppIntent { static let title: LocalizedStringResource = "intent.title" static let description = IntentDescription("intent.description") static let openAppWhenRun: Bool = true @Parameter var duration: IntentDuration @Dependency private var appManager: AppManager @MainActor func perform() async throws -> some IntentResult { // My action return .result() } } However, I get the following error from Xcode at the @Parameter line: 'init()' is unavailable Did I wrongly understand how this works? Is there another way to accept multiple types for a parameter? I didn't manage to find any docs on this.
