Retina support for the newer iPads requires the app be built using at least iOS 5.1 SDK.

I have Xcode 5? Where are the other SDKs?
Xcode's iOS SDK is downwards compatible with a range of previous versions of iOS, but only one SDK is supplied with a particular Xcode version. To support a range of iOSs, set 'Build Settings/iOS Deployment Target' to your choice from the list provided.
What about older* versions?
- The last OS X that supported Xcode 3.x was Snow Leopard.
- OS X Snow Leopard/10.6.8 is required for iOS support.
- There is no OS X that supports both Xcode 3.x and Xcode 4.3.x.
- There is no OS X that supports both Xcode 4.0.x and 4.3.x.
- The latest Xcode for Snow Leopard is 4.2.
- Xcode 4.3.x is only supported on Lion or higher.
- Some older Xcode versions are available to registered developers with an active paid Developer Account via *developer.com.
Can I develop applications for Mac OS X with ARC using Snow Leopard?
No. The Snow Leopard version of Xcode 4.2 doesn’t support ARC at all on Mac OS X, because it doesn’t include the 10.7 SDK. Xcode 4.2 for Snow Leoparddoes support ARC for iOS though, and Xcode 4.2 for Lion supports both Mac OS X and iOS. This means you need at least an OS X Lion system to build an ARC application that runs on Snow Leopard.
