Possible bug in Visual Studio for Mac 7.7.4

Hi All,

I am new to Xamarin, but I have 18 years development experience in .Net.

I upgraded to VS2017 Community Edition for mac to version 7.7.4 today.

I then started getting the following event error code. The attached error code was generated when I tried to enter values into Single Line enty in the FormsGallery project using the iOS simulator.

I am getting the same error in my main App project, interestingly the App has not crashed, so I am trying to determine whether the issue is in the application, the sumulator, or the Application output log.

I hope someone can help.

Regards

Ross

Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.
(Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)

Will attempt to recover by breaking constraint

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.
