I was trying to set a class to be a persistent data source using @Model annotation, and somehow this happened:

enter image description here

The code above is generated by the compiler and the error is located in it.

Here is my code:

import SwiftData

class Animal {
}

@Model
class Dog: Animal {
    let breed: String
    init(breed: String) {
        self.breed = breed
    }
}

However, when I declare the Dog class with no super class, it work as expected.

Any idea?

    Don't use inheritance together with SwiftData, that's my recommendation. Maybe it will work later but right now the Model macro doesn't support it. – Joakim Danielson Aug 10 '23 at 14:46
  • I was trying to use SwiftData in my project, and the same error occurred when I tried to apply the `@Model` annotation to a class that inherits from `NSObject`. Turns out the issue is related to a model with inheritance. – catmotionmachine Aug 10 '23 at 15:12
