(Very) limited otool like tool written in Swift.
For educational purposes only. Obviously don't use this and prefer the more reliable otool
I wanted to play around with the Mach-O format and try to parse it to retrieve various infos like otool does.
Only supports printing the Mach header and load commands.
USAGE: slotool [-h] [-l] <input-file>
ARGUMENTS:
<input-file>
OPTIONS:
-h print the mach header
-l print the load commands
-?, --help Show help information.> slotool -l /bin/ls
