I've tested two of our apps that were built in Xcode 4.2 for iOS 5.0 and greater on an iPad II running iOS 6 and a gen 4 iPod Touch with iOS 6 and the apps run as expected.
Another group wasn't so lucky, but I don't know the reason behind the failure.
> What I'm wondering is going forward can I still compile my app using Xcode 4.4.1 with the iOS 5 SDK and submit it to the app store. I want one of my apps to continue to run on the iPhone 3G (armv6) so I'm trying to figure out if I can just keep Xcode 4.4.1 and use it for that while using the Xcode 4.5 for my other app that is iOS 5 and higher. Or do I have to somehow use lipo to add the armv6 binary from Xcode 4.4.1 to the .app created with Xcode 4.5 and then somehow make certain it's still signed correctly.
What I'm planning on is testing running OS 10.6.8 Server under VMware to see if I can run Mountain Lion and build and deploy and without rebooting my Mac to another partition or moving the code to another box, also build off an older version.
As we move forwards, I know it will end up biting our group if we do not plan for and test that now.
The other group that I mentioned previously still has to support iOS 2.x and they don't have the testing staff, budget and number of devices to support to properly test their product on every device and iOS version up to and including iOS 6. It's put them in a bad spot since their app crashes on launch on iOS 6. How someone will manage that, I have no idea, but I can foresee that we will have to support from iOS 5, 6 and 7 all at the same time.
Apple would be really really nice if they allowed us to deploy to that many iOS versions from one build of Xcode.
