Xamarin iOS 模拟器黑屏 Xcode 11更新

Question

I am using windows PC and Xamarin.I have recently updated Xcode to 11 on Mac. I am running VS 15.9.16. After the Xcode update, my Xamarin Forms app never loads. The iOS Simulator simply shows a black screen after launching. I have tried multiple other form factor simulators. All show the same symptoms.

Answer 1

In my case, it goes black in iOS13 after launching. After some googling, I found the solution for my problem which was unchecking/set to false "Supports multiple windows". Hope it helps.

Answer 2

You may be using a deprecated class like UISearchDisplayController that stopped working in iOS13. That caused the black screen for me.

Answer 3

In my case, simply switching from iPhone 11 to iPhone SE simulator did the trick. I am assuming if this works, switching from the current selected device to a different device could be all you need.
