use of @Model macro from SwiftData causes project build to fail

Target

tvOS 17.4

macOS Version

14.5

Xcode Version

15.4 (15F31d)

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
