Andy Lee’s AppKiDo is free, source is available, and it’s drastically better than XCode’s doc viewer. And this is the third or fourth time I’ve discovered it only to later forget all about it. Maybe writing this note about it will help me remember. It’s worth the download just for its consolidated method lists (one of my biggest gripes with Apple’s AppKit documentation). Get it here. I wish Apple would adopt this and ship it with XCode.
