I am working on integrating SwiftData (not migrating from CoreData) into an app in active development for tvOS, and I cannot get the project to compile whenever the @Model macro is introduced.
I've traced every error back to the code generated by the @Model, and commenting it out removes the errors. I am able to use @Model on a fresh project, but any attempt to import SwiftData results in the build failing with the following errors:
/var/folders/t5/c9qp7_4j19x9s3p3z26kn6v80000gn/T/swift-generated-sources/@__swiftmacro_9AeolusKit11DeviceModel0D0fMe_.swift:1:1 Type 'DeviceModel' does not conform to protocol 'Observable'

the code in question causing the error:
import Foundation
import SwiftData
@Model
public final class DeviceModel {
@Attribute(.unique) public var id: String
init(id: String) {
self.id = id
}
}
I've already done the following:
- clean the project
- erase the contents of the
derived
directory - restart xcode
- restart my mac.
I want to emphasize, I do not believe it is my code causing this issue, as commenting out the @Model result's in a perfectly normal build with no warnings or errors
Any help is appreciated
