Created attachment 24335 [details]

When I change a Width constraint of a button from = with constant = 0 to <= in the pop-up box which opens after a DoubleClick on the constraint in the designer window the designer crashes with the attached Exception. The 'Reload Document' button does not reload the document. Have to close and reopen.

This looks to be an issue with the iOS Designer, as opposed to the Xamarin.iOS product itself, so I'm moving it to that product.
