Migrating xcode project 4.2 to xcode 7.0

Question

I am migrating project from xcode 4.2 to xcode 7.0 and facing exception like this...

This application is modifying the autolayout engine from a background thread, which can lead to engine corruption and weird crashes. This will cause an exception in a future release.

and app will be crashed after few seconds.

I have removed all reference from storyboard scenes and compile source. But problem remain same.

put the break point and check once you were called any thing in background thread, if yes change your thread to main

dispatch_async(dispatch_get_main_queue(), ^{
    // add your code here
});

check this also may be it helps
