What is wrong with Xcode? Why are people complaining about it?
I haven't encountered any major issues in recent versions.
I mean, for one, it's absolutely massive. Not great when the associated CDN with delivering it is excruciatingly slow too... I don't really use it though, I do sysops stuff and have no use for it. I guess that's another mark against it though; as an IDE it's fairly useless for anything you don't intend to exclusively deploy to Apple platforms.
