So far I have just opened Xcode DP3, haven't had the time to play with it. But I did notice those (ugly) new flat icons. I'll definitely have to keep a copy of Xcode 5 and steal them from the package, this is not acceptable. Also in the constraints area, you get a new diagram clearly depicting what constraints you added. This is a nice touch. However, I still find myself not understanding how to remove ONE constraint at a time. It seems like all I can do is remove all of them and start from scratch. Any other changes ?
