Bug with Transferable + AppEntity
Hello all, I'm finding myself with a compile error when trying to use a defined UTType for Transferable conformance when the type is also an AppEntity. The compiler error is Could not determine the identifier of `.todo`. Please use a UTType defined by the UniformTypeIdentifiers framework However, said compiler error only shows up after adding AppEntity conformance. So, in order to reproduce: Create any type, conform to Codable struct Todo: Codable { var id: UUID var title: String var completed: Bool } Create a UTType extension for the new type extension UTType { public static let todo: UTType = UTType(exportedAs: "org.nameghino.types.todo") } Add Transferable conformance extension Todo: Transferable { static var transferRepresentation: some TransferRepresentation { CodableRepresentation(contentType: .todo) ProxyRepresentation(exporting: \.title) } } At this point, the code compiles correctly on Xcode 16.2 beta 2 (16C5013f) Add AppEntity conformance extension Todo: AppEntity { static var typeDisplayRepresentation: TypeDisplayRepresentation = "todo_title" static var defaultQuery = Todo.Query() var displayRepresentation: DisplayRepresentation { DisplayRepresentation(title: "\(title)") } struct Query: EntityQuery { typealias Entity = Todo init() {} func entities(for identifiers: [UUID]) async throws -> [Todo] { return [] } func suggestedEntities() async throws -> [Entity] { return [] } } } Now the code is not compiling with the aforementioned error.
