NSInvalidArgumentException is a very generic failure. AFAICT there’s no indication that your crash is related to the other crashes on this thread. Specifically, in the other cases the crashes were coming out of CFNetwork but in your case it’s coming out of UIKit.

I recommend that you start a new thread for your crash. Tag it with UIKit and Debugging. It’d be best if you included an Apple crash report; I can’t do much with third-party crash reports [1].
