After testing my Xamarin.Forms app in IOS simulator for a while, I started to do so on a physical device. On simulator it works without any problem, but on my IPhone 6 a very strange exception crashes my app. It happens in a really simple view, that contains only a listview and a search view as a stack. ListView has a pull to refresh feature (I use the built in one of Xamarin), and after pull to refresh this exception crashes my app:
Message:
NaN is not a valid value for height
Stack Trace:
Xamarin.Forms.Size..ctor(Double width, Double height)
Xamarin.Forms.Grid.OnSizeRequest(Double widthConstraint, Double heightConstraint)
Xamarin.Forms.VisualElement.GetSizeRequest(Double widthConstraint, Double heightConstraint)
Xamarin.Forms.Layout.GetSizeRequest(Double widthConstraint, Double heightConstraint)
Xamarin.Forms.StackLayout.CompressVerticalLayout(Xamarin.Forms.LayoutInformation layout, Double widthConstraint, Double heightConstraint)
What can be the problem? Note again: it does not happen in simulator, just on my iPhone 6.
