This just started happening that my iOS project is only showing "My Mac 64-bit" rather than the Simulator or my iPhone to build to. I have no idea why this is happening. I do not think that I have changed anything. I have my project set to iOS 5 as the base SDK, but no matter what I do it seems to never show my any other options to build for. I have restarted Xcode a few times, and still no luck. Why is the happening? XCode 4.2, Build 4D199

Often times this can happen when some files change without xcode's blessing. As in when switching between version control branches.Usually restarting Xcode fixes that problem.
