Why doesn't mono support arm64?

In Unity Editor, iOS Player Settings, Architecture can’t be changed to Universal if Scripting Backend is Mono2x.

I already tried searching google but got nothing.

Any page discussing this question would be nice :slight_smile:

In the past, the Mono arm64 AOT engine and runtime were not open source, and Unity did not have the proper license to use them.

For 64-bit support on arm64, you will need to use the IL2CPP scripting backend.
