It was head and shoulders above many of the alternatives for mobile app development back then like Carbide or Codewarrior, though.

For the most part it was great (IMO), and has some features I still miss in all other editors, like the automatic side-by-side toggling, using mouse gestures (on Apple's mouse) to go back / forward in history just like Safari, etc.

The most friction came from merging (e.g. when files were changed or project config was changed), due to xcode's insistence on having a project file listing all files etc. The other friction was in the annual update cycle of both xcode and the apps we built.

But the last time I tried xcode it was pretty bad; on paper the new UI coding approach is great, but in practice the live preview was so tempramental and crashed so often it was barely usable.
