On macOS, is there any way to programmatically get (from C or Swift) the same architecture info that file produces when run on an executable? E.g.:
$ file /Library/Audio/Plug-Ins/HAL/ACE.driver/Contents/MacOS/ACE
/Library/Audio/Plug-Ins/HAL/ACE.driver/Contents/MacOS/ACE: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit bundle x86_64] [arm64:Mach-O 64-bit bundle arm64]
/Library/Audio/Plug-Ins/HAL/ACE.driver/Contents/MacOS/ACE (for architecture x86_64): Mach-O 64-bit bundle x86_64
/Library/Audio/Plug-Ins/HAL/ACE.driver/Contents/MacOS/ACE (for architecture arm64): Mach-O 64-bit bundle arm64
$ file `which plutil`
/usr/bin/plutil: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit executable x86_64] [arm64e:Mach-O 64-bit executable arm64e]
/usr/bin/plutil (for architecture x86_64): Mach-O 64-bit executable x86_64
/usr/bin/plutil (for architecture arm64e): Mach-O 64-bit executable arm64e
I know I can invoke file from my code, but I’m looking for a library call I can make.
