I'm running XCode 7 beta 5 but this also happend to me on beta 4.
When I'm debugging an OSX application and execution stops sometimes the application gets stuck as not responding and won't close. I haven't been able to notice a consistent pattern of when it happens or not.
The stuck app doesn't show up in activity monitor at all. Also, it won't force quit but shows up in the force quit dialog and on the dock.
After this happens, when I test the app again in XCode it creats a new instance of it. After a few hours of coding I can have 3 - 6 of these stuck "zombies" on my dock.
The only way I can get rid of them is
1) Sometimes quitting XCode clears them
2) Sometimes quitting XCode doesn't clear them they clear when I restart XCode
3) If they don't clear from restarting XCode restarting my computer clears them out
Things I've tried:
At first I thought this was a memory management issue in my app (and maybe it still is) but I'm programming in Swift so I'm not handling any of that directly. I then thought maybe it was the result of some closures keeping things around so I made sure to use weak self in those. I've also theorized that some notifications were keeping things around but I've unregistered those notifications in deint.
Is this a bug in XCode 7 (it only started happening when I upgraded to XCode 7 on this app) or something my app's user's could face?
Has anyone else seen this?
