 * branch            main       -> FETCH_HEAD
 * [new branch]      main       -> origin/main
HEAD is now at 1a887c2 appkit: mark makeCoordinator with MainActor. * The appropriate method that should NOT have a main actor is   determineViewSize, since that will break compiling with swift 6   strict concurrency.
