I want to add a little feature to VLC only on Mac.
How can I build and debug it? May I use Xcode? Or I should use something different? I download sources from github, I can see Mac OS gui module. But how can I debug it?
It seems that @feepk's answer is outdated. You can use Xcode to debug VLC on macOS.
VLC.app
.vlc/extras/package/macosx/VLC.xcodeproj
