I don’t care for the design of iOS 7 on the iPad, but Xcode 5.0 is something I’ve been looking forward to for a long time. (Mavericks is another one.) I’m currently downloading it myself, so I am not sure if anything has changed from the GM, but I will be updating this post with anything and everything I can find. If you’re as excited as I am, and you want to download it, keep in mind that Apple’s servers are really bogged down right now. It is a 1.9 GigaByte file, so you are going to want to go get some lunch (if you haven’t already) and let this thing download and install.
Hope you have fun with it!
