Xamarin iOS app displaying white blank screen on iPad after update to Xcode 11

Question

I have a Xamarin.iOS app developed on Visual Studio 2019 and paired to a Mac. The app was displaying correctly on both iPhones and iPads until I updated Xcode on the Mac to version 11. Since then Apple is rejecting my app because is displaying a white blank screen on iPads (see image below!).

I have validated the issue on Xcode Simulator and on a physical iPad. Does anyone have an idea of why this is happening?

Answer 1

Assuming you have your iPad Pro connected to the same local network as your Mac, and you have enabled Xcode wireless debugging for the device, then you can target your iPad as a device to Build & Run on. Making it a seamless experience to test on the same device you're using to do the development.
