MT4109: Failed to compile the generated registrar code

[bonbon2106]

I'm using VS 2019 (version 16.2.5, .Net Framework 4.7.03190) on Window and pare with MAC to compile my project. After updating Xcode on MAC to version 11.0 (11A420a), I get an error while building my project with the following message:

C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Xamarin\iOS\Xamarin.iOS.Common.targets(804,3): error GEA45E82A: expected identifier or '{'
2>C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Xamarin\iOS\Xamarin.iOS.Common.targets(804,3): error MT4109: Failed to compile the generated registrar code. Please file a bug report at https://github.com/xamarin/xamarin-macios/issues/new
========== Build: 1 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

Please help me to check this issue.

Thanks so much!

The problem is that your Mac auto-upgraded Xcode to the new Xcode 11, and our current version of Xamarin.iOS is not compatible with Xcode 11.

We'll release a version of Xamarin.iOS that is compatible with Xcode 11 later today. A more immediate solution is to install our preview version of Xamarin.iOS with support for Xcode 11.
