Why swift app IPA crashes when I open the app ?

I have created app in Swift language and install that IPA (Distribution profile) on the my iPad, the app getting crash. But I run through debug mode its running correctly on the same device. Can you give the solutions for this crashing ? and How do I fix this issue ?

Xcode version : 6.3.1 iOS version : 8.3
