ios - My app crashes XCode on device, no crash on simulator -

after big changes made in ios app, (mainly removing parts objective c framework , use in swift app)   running app on device without breakpoints crashes xcode ( not app ) error message of xcode below. running same app on simulator not crash xcode. running app on device not crash xcode.

does not matter whether have breakpoint or not.
