Cannot compile any projects with macos 11, not matter it is new or exists

It seems that /System/Library/PrivateFrameworks/MultitouchSupport.framework/Versions/current/MultitouchSupport is no longer exists in macOS11 beta.
Does it can be solved now? or it can be only solved by the following version of UE4?
version:
macOS 11 beta
Xcode 12 beta
UE 4.25

Released version of Big Sur and xcode still have the same issue. I see where it is in the build files( https://github.com/EpicGames/UnrealEngine/search?q=MultitouchSupport ), but not sure what this was being used for and if it’s been moved or deprecated… anyone have more knowledge on this?

I have the same issue trying to build UE 4.25.4 fresh from source on a newly updated Big Sur with XCode 12.2.

The output shows several sporadic entries of clang: error: no such file or directory: '/System/Library/PrivateFrameworks/MultitouchSupport.framework/Versions/Current/MultitouchSupport

Ultimately my builds all fail with “XcodeBuild.sh failed with exit code 6”, for which I can’t find any references. Do you get something similar?

The problem is most likely caused by XCode 12. Since UE 4.25.x supports only XCode 11 you will run into issues.
You may want to wait for release of UE 4.26 which is really near.
The only workaround is to download the old version of XCode, eg XCode 11. Then you will be able to pack your project and upload it to AppStore and It should work just fine (except for iPhone SE and iPhone 12), however you will most likely run into issues when launching your project on Devices with iOS 14 directly from the editor.

If you are comfortable modifying your local copy of the engine you can implement this change yourself, and I have confirmed it works! Have a different issue with packaging now, but can at least work on it!
