Im’ writing an phone app in Xcode 4.2. At some point in the last few days, I changed something – I don’t know what, and there’s nothing obvious in the git history – and although I can still run it on my device and in the simulator, when I archive the build it makes an archive instead of an app. I can’t share these archives as IPA files; if I try I get told “No packager exists for this type of archive”.
What did I do? How do I change it back so I can produce IPAs again?
Make sure for any intermediate targets you select “Skip Install” for its build settings.
