i have the same issue. it happened, then I restarted the macbook pro and it worked once... when I tried it again, it crashed again. I tried a simple copy of a view controller on the same storyboard, and it crashed...How can we do production level work on something so unstable.I also have a nagging codesign error that fails my builds about 30 percent of the time, and that gets up to 100%, and a shut down of xcode tends to make a little better temporarily.I wish someone would make sure they don't break things before adding new stuff.
