Downloaded the SDK and installed Xcode. Created new project (ReturnToMe from iPhone for Dummies) and left the windows open. Next day I wanted to start anew so I closed all windows, and when I launched Xcode it said 'Xcode quit unexpectedly'. Reopen would not do anything, restart would not do anything. I clicked on the SDK and XCode for Mac packages and apparently reinstalled, but XCode will not launch. Now it keeps coming up with a technical report of how many times it has crashed.
First experience with Apple, and very frustrating .. what can I do?
