Summary:

I’d say probable half of the time in a medium-size Swift project this occurs. I pause at a breakpoint, click to see back a few frames from the current breakpoint, and it crashes. That’s exactly what happened here.

- I set a breakpoint
- Ran app in iPhone 6s 9.2 sim
- Xcode paused at the break point as expected 
- I pressed Command + 6 to see the paused stack
- I clicked 2 frames back from the one at the top of the stack
- Xcode crashed.
