Comment 4 Rajneesh Kumar 2015-02-06 07:01:34 UTC
I am able to reproduce this issue with the Xamarin.iOS 8.6.1.10 and Xamarin.iOS 8.6.0.51. Here is the screencast for the same:

Screencast(X.iOS : 8.6.1.10): http://www.screencast.com/t/fdF8wc5sGPOI
Screencast(X.iOS : 8.6.0.51): http://www.screencast.com/t/jRYqZFCQvSo

I have checked this issue with Xamarin.iOS 8.6.1.20 (Beta)  and observed that this issue has been fixed. I am able to deploy the application successfully without any crash.

Hence closing this issue with respect to X.iOS 8.6.1.20
