        In Xcode 11, more or less every time I paste anything within a storyboard or between storyboards, Xcode just crashes immediately and disappears. This is maddening! I am having to open my storyboards as source code and copy and paste storyboard source code to get anything done.

          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.
