I have Xcode 4.2.1 which came with an installer and put itself and numerous associated files into ~/Developer I downloaded Xcode 4.3 which does not include an installer, just the app. Should I simply replace 4.2.1 which is in ~/Developer/Applications or should I do something else?
Open Xcode.app in
/Applicationdirectly.The first time you run Xcode 4.3, you are prompted to remove older Xcode in
/Developer, you can cancel it and remove/Developerin later.https://developer.apple.com/library/ios/#documentation/DeveloperTools/Conceptual/WhatsNewXcode/Articles/xcode_4_3.html
