Question

I currently have Xcode 4.1 installed. I attempted to update using the App Store so that I can test my app in iOS 5. The update program downloaded properly, and it took quite a while to perform the update, whereupon Xcode relaunched.

I couldn’t find iOS 5 in the deployment target list, and I checked the “About” section, and found that I was still using Xcode 4.1, build 4B110, not Xcode 4.2, build 4D199, as described on the download Xcode 4.2 page.

I ran the update again, without any luck. I attempted to download the update again from the app store, but it just has a blue button saying “installed”, and no obvious way to force a reinstall. The page on the app store clearly says Xcode 4.2, so that is what I would expect to have by now.

Has anyone run into the same issue? After quite a bit of googling, it would appear that this is not the case. I would be interested to hear any hypotheses, or solutions.

Move your /Developer directory to something like /Developer-4.1, then install Xcode 4.2 again using /Developer as the install path. After the install, inside /Developer/Applications/ should be the new Xcode 4.2 that you want to use.

[ 16:44 Jonathan@MacBookPro / ]$ sudo mv /Developer /Developer-4.1

This is how my / looks like from all the different versions:
