On my personal machine (Sequoia, xcode 26.1.1) I successfully made a demo similar to: ( Using Observations to observe @Observable model properties – Donny Wals ) using the Observations type in a non-SwiftUI class and attached it to a View via .task. However when I attempted the same code on my work machine (Tahoe, 26.1.1) it warns that the class does not conform to sendable. I got around that by making the class conform to @unchecked Sendable but I really need to observe changes on lots of @Model types with strict concurrency. Any guidelines would be appreciated
