Hi,
Everytime I try to create an entity in the core data model Xcode crashes. I've even gotten so far as to be able to create the ns managed subclass but as soon as it does that it crashes and upon reopening the entity is no longer there. Any suggestions. Using Xcode beta 3 latest.
It's possible that this is caused by the presence of old runtimes as mentioned in the Release Notes:
Xcode processes may quit unexpectedly if older iOS Simulator runtimes (Xcode 6.x) are present on disk
To see if that's the case (or to rule it out as a cause), delete all (old) runtimes from /Library/Developer/CoreSimulator/Profiles/Runtimes.
Hello, i have a new installtion with all latest software version, and xcode crashed by deleting a entity, each time
Open that project again, then hold the option key, use Xcode's Project menu and choose to 'clean build folder'.
See if that helps and good luck.
I had a similar problem: every time I was doing any operation on the CoreData model (e.g. create a new entity and try to save it), it was causing Xcode to freeze and I had to force-quit it. In my case, my Xcode project folder was synced with Google Drive: as soon as I moved it outside of Google Drive, I was able to use the CoreData model again!
I found I could fix this by deleting the app from the simulator. Still, this is a bug that should be looked at.
