I'm still encountering this issue and so confused there should not be an so obvious bug here. Recently I decide to make App purely relying on SwiftData: 1. reading from network 2. write to context 3. only read data when notified without interrupting context writing. For the notification object, I tried context, context.self, and even the actor calling the context.insert. None of them works. Really need help!

mark your class as @unchecked Sendable and try

yes, you can only use static or let value in Query predicate at declaration.
