Crash iOS app in start


I have a problem with testing app on IOS device :frowning:
Some times when I run my ionic app on IOS device,everything works well, even if I run it again without Xcode.
But some times when I try to run my app on iOS device it doesn’t run (it try to run but crash immediately).Then I try to run app on device from Xcode,but Xcode show me error (in Attachment)

Please,help me!
How I can fix it problem ?
