How can I run iOS 4.3.3 developed apps on iOS5?

Question

I upgraded to iOS5.

I am building an app using XCode4 targeting iOS 4.3.3.

Will I need to download XCode 4.2 to run my iOS 4.3.3 target?

Answer 1

You cannot debug on your device without a version of XCode that expects iOS 5, but you can still install software using iTunes.

Build your app as if you were to distribute it for beta testing:

• Create a Distribution Certificate with your device UDID

• Build and Archive

• Share -> iOS App Store Package (.ipa)

Drop the resulting .ipa file into iTunes, then sync your iOS 5.0 device with iTunes.
