Agreed. There were the usual problems with getting used to a new interface layout, but IMO Xcode 5 is a major improvement. It seems faster (I haven't done any metrics though; possibly it's just the more streamlined workflow) and is definitely less crashy.
I'm doing PhoneGap stuff, so the platform restrictions aren't really an issue for me.
I have to agree with you. 6 is MUCH, MUCH better! As far as platform restrictions, I just meant with iOS in general. Its a lot more restricted than other platforms. Ive been doing a lot with PhoneGap on Android, but haven't had any luck on iOS. The problem I run in to the most has to do with archiving and validating.
