What's the problem?

Since June, 22nd 2020, Apple released Xcode 12, that introduced an internal change to Xcode, breaking arm64e compilation for tweak developers. This is due to the update of clang/LLVM (AFAIK) in Xcode 12.

Details of the problem

More specifically:

• compiling code for arm64e with Xcode 11 Toolchain will allow this code to run only on iOS 13 and lower for all versions!.
• compiling code for arm64e with Xcode 12 Toolchain will allow this code to run only for iOS 14 (and up).

No error is produced during compilation. arm64 slices are not concerned and will always work.
