I've upgraded the Xamarin Studio and Xamarin.iOS because I've not used them for months.
After that I have these version:
Xamarin Studio Version 5.9.5 (build 10)
Xamarin.iOS Version: 126.96.36.199
Now I'm trying to debug an application through an iPhone but the "Start debugging" button is disabled.
It is possible to run the app in the iPhone but without debugging.
How is it possible to enable this button to debug the app through an iPhone?
