Xamarin-macios: mtouch errors after updating Visual Studio 2019 through "Xcode 11 Previews" channel

Created on 23 Aug 2019 · 7Comments · Source: xamarin/xamarin-macios

I updated the VS in the channel "Xcode 11 Previews" some days ago. I could deploy my app on iPhone(ios 13) without any problem. Today (23 Aug), I downloaded the latest updates of Visual studio. Consequently, I can not build the code anymore. Visual Studio shows me two errors although I did not touch the code from yesterday.

Steps to Reproduce

Update the Visual Studio through "Xcode 11 Previews" channel

Expected Behavior

The app was deployed on iPhone 7( ios 13) without any problem.

Actual Behavior

The errors:

myApp/myApp.iOS/obj/iPhone/Debug/device-builds/iphone9.3-13.0/mtouch-cache/registrar.m(4,4): Error GBDAA8BF8: cannot find protocol declaration for 'UIContextMenuInteractionAnimating' (GBDAA8BF8)
myApp/myApp.iOS/MTOUCH: Error MT4109: Failed to compile the generated registrar code. Please file a bug report at https://github.com/xamarin/xamarin-macios/issues/new (MT4109)

If you look in ~\Library\Caches\VisualStudio\8.0\TempDownload\ you may still have the old Xamarin.iOS-12.99.2.40.pkg installer.

Re-installing that old version helped fix the issues I saw in #6838, #6839. Hope this maybe helps you :)

Thank you, Ewan. I downgraded the Xamarin.iOS to the version "12.99.2.40"
as you suggested. It works correctly.
