Xcode 12.5 Beta 2 fails to compile MMEEventsManager.m, 'TARGET_OS_MACOS' is not defined

[roblabs]

While testing the Examples app in this repo with Xcode 12.5 Beta 2 there is a blocking compiler error related to MMEEventsManager.m.

• Compiler error occurs with Xcode Version 12.5 beta 2 (12E5234g), released Feb 16, 2021 using Examples.xcworkspace
  • Issue occurs in Version 12.5 beta 3 (12E5244e) released on Mar 2, 2021.
• The demo app in Examples.xcworkspace works as expected with Xcode Version 12.4 (12D4e)
• The Podfile.lock shows that the MME version is MapboxMobileEvents (0.10.5), so this may be fixed in MapboxMobileEvents after this version.

The fix may be as simple as upgrading the mapbox/mapbox-events-ios in the Podfile. Change would have to occur in mapbox/mapbox-gl-native-ios as the Podfile only points to the 6.3 release for iOS, and the MME is not configurable via the Podfile.
