I have a similar problem. There is a not elegant solution: force cast. switch item: case is Item1 let binding = Binding(...) RowView(item: binding) default: fatelError("Unknown Item") }

Same problem if I append a value to path (NavigationPath). Tested in Xcode 14 beta 5

How about: ForEach(department.students) { student in Text(student.name) }

You should extract a variable for the name. let tmp = other.name #Predicate<OnlyName> { $0.name == tmp }

@Relationship(.nullify, inverse: \Group.members) var group: Group group must be optional

It seems no method to get the mainContext injected in environment directly, and the context is not sendable, you can not use it on other actor/thread. But you can get the context from your model like model.context. actor BackgroundActor: ModelActor { nonisolated public let executor: any ModelExecutor init(container: ModelContainer) { let context = ModelContext(container) executor = DefaultModelExecutor(context: context) } func run(task: (ModelContext) -> Void) { task(context) } } You can use this wrapper like this: databaseActor.run { context in // .... }

AFAIK Create a view history table and apply cascade rule
