New in Xcode 14, Xcode will attempt (with your permission) to merge your watchOS targets into a single target. Since the beginning, watchOS apps always had an App Target and an Extension Target. I believe this is from legacy watchOS 1 where the code would run on the iPhone but the assets would run off the watch. Anyway, in Xcode 14, there is now a way to combine these into a single target. In Xcode 14 Beta 3, I attempted to let Xcode 14 do this migration for me to the single-target and while no issues happened, my app on watchOS now fails to launch. It points to a crash on @main on my ExtensionDelegate class. There isn't much in the debugger other than: Couldn't instantiate class _TtC30PDX_Transit_WatchKit_Extension23MainInterfaceController Any ideas of where I can begin with this?
