Issue Description:

I'm getting an "Abort trap 6". I don't know how much of it is related specifically to the nested Coordinator aspect.

Here's a much smaller reproducer:

protocol MyProtocol {}

func crash() -> some MyProtocol {
  class MyClass: MyProtocol {}
  return MyClass()
}

One workaround is to move your Coordinator class outside and rename it to something else. This will prevent the crash for now.

I have a potential fix here: #33035
