iOs Designer is not working

I am struggling with iOs designer in my Xamarin Studio.

Xamarin Studio Community Version: 6.1.3 (Build 19)
Linked Xcode Version: 8.2.1

I am not sure why it is keep on happening because it first happened and at that time I opened the storyboard in xcode 8 and the issue went away but since I started using Xcode 8.2.1 I am getting this errors and I am not able to use iOs designer of Xamarin Studio.

Can anyone suggest solution?

I have attached a file(Logfile2.txt) which has detailed information of the errors.
