Hi,

Thank you for your example project.
I compiled and run in iOS simulator and no problem. And after a few hours of trying I found that if I changed Transition property to Value "SlideOnTop", then the error appear on iOS platform.

I modified my project.

Thank You for your help.

Regards.

In my case; I also get a crash only on the iOS (and not on the UWP) but I do get the crash if I do set it to Transition.Push; in Transition.SlideOnTop it works.

Appreciate a quick "hotfix" or turnaround for this one.
