According to the documentation, this api is available on iOS 8.0 to 14.0, but after specifying the version with @available attribute on xcode beta3, the following warning still appears when compiling.
This problem does not exist on beta2. It seems to be a bug introduced by beta3. You can build the attached test project with Xcode 13 beta3 to reproduce.
This was deprecated in r256715 and the macro was updated in r271813.
