breakpoint is grey out for properties inside @Observable

Yep. I’m seeing the same thing with the tiny test tool (see the end of this post). I’d appreciate you filing a bug about this. Please post your bug number, just for the record.

import Observation
 
@Observable class Test {
    var test: Int = 5 {
        didSet {
            print("did set")
        }
    }
}
 
func main() {
    let t = Test()
    print("before")
    t.test = 1
    print("before, \(t.test)")
}
 
main()

Done. Thank you

Observing (heh) the same behavior as of Xcode 16.2.
