Odd issue: one of my apps crashes at launch on iOS 11 devices when run from Xcode (8 or 9beta4, both the same). If I open the app afterwards from springboard, it opens and works fine.
The backtrace isn't too revealing. It looks like it's calling [CALayer display] on a GLKView (there are a few of those in the app, but at this point none have drawn anything). It's then calling out to SceneKit's SCNGetPerformanceStatistics, followed by something for OpenSubdivision, and crashing on a memmove. SceneKit isn't used at all in the app, neither is subdivision of any kind.
Anyone seen anything like this, or have any ideas on how to debug? Or is it likely to be fixed in a future beta?
