Xcode 4.2 project ported to Xcode 4.2.1

Sorry if this is not considered a sufficient programming issue for SO (this is due to the development around the round).

I have an iMac on 10.6.8 (Snow Leopard). I was working on an iOS 5 project using storyboards that would not work on our test iPhone (this was in version 4.3.5). I upgraded the iPhone to iOS 5.0.1 in the hope that this will fix the problem.

Connect the phone, you can’t select it from Xcode 4.2, because it only supports iOS 5.0 and below. So now I have to upgrade to Xcode 4.2.1, which requires upgrading iMac to 10.7 (Lion). After I shook my fist and cursed Apple, I talked with my manager to let me make all the necessary updates. However, I would like to make sure that I have a few things before I move on to this:

  • Will my Xcode 4.2 project still be open in Xcode 4.2.1 (or is there a safe way to convert it). I would prefer not to rewrite the application.
  • I saved the Xcode project folder to a USB key to ensure that I won’t lose the application. It also saves the git repository (where is the git repository stored by default? Would I like to keep a history if possible)?
  • What do I need to do with respect to the developer and distribution keys and certificates? Do I need to export them and reimport after upgrading to 10.7?
  • Is there anything else I need to back up before performing this update (related to my iPhone app and everything else related to development / distribution)?

TIA

  • Yes. No need to convert.
  • Git Reproduction is saved in the top-level catalog of the project. You can safely transport it through a USB drive and not lose the repo.
  • Some time has passed since I upgraded to 10.7, but I don’t remember that I had to regenerate my certificates.
