Xamarin Studio - Ctrl + Drag to assign Root View Controller - ios

Question

I am going through the Xamarin Hello.iOS tutorial and there is an issue when trying to complete steps 6 and 7 from the following...
https://developer.xamarin.com/guides/ios/getting_started/hello,_iOS_multiscreen/hello,_iOS_multiscreen_quickstart/
The issue is that when I do the Ctrl + Drag from the Navigation Controller to the View Controller. The Pop over they mention doesn't stay open so I can't select Root.
I am on macOS Sierra 10.12.1 and the issue seems to occur on both Xamarin Studio and Visual Studio for Mac.

Answer 1

Unfortunately, this seems to be an issue with the Force Touch feature on the trackpad. If you disable Force Click and haptic feedback it should work as expected. That fixed it for me anyways. I'm surprised that Xamarin/Microsoft hasn't fixed this issue yet.
Go to System Preferences > Trackpad > Point & Click and uncheck Force Click and haptic feedback.
This was also asked here.

Answer 2

I came across the same issue, from MacOS Sierra and VS for Mac. The only trick that worked for me is to use a mouse instead of trackpad...
This way, the context menu stays open and I am able to set the navigation.
