Hi, Sometimes app getting failed to identify the edge and its getting crash. In Log is displays Missing 1, Missing 2 ( NSLog(@"MISSING %i", i);), then its crash. Below I have included Log.

The app was working fine before updating to swift2.3 to swift 3 (i have created bridge header) and Xcode to 8.3.2.

Do you found any solution?

Not yet, only alternative way to make it work is by disabling auto edge detection and only allowing manual crop.
