This question is out-dated. Mavericks is released and everything works fine with Xcode 5 and iOS 6 on an iPod 4th gen.
I'm thinking about upgrading my OS X to Mavericks, but I still want to keep developing my iOS app. I read on the internet that Xcode 4.6.3 is not compatible with Mavericks (OS X 10.9). So, this would force me to use the new Xcode 5. However, Xcode 5 comes along with the new iOS 7 SDK. The problem is that I own an iPod 4th gen, which isn't compatible with iOS 7.
So, has anyone tried this already? I think this should be possible, because at the WWDC 2013, Apple was so proud to tell that more than 90% of the costumers work with the latest iOS, which is currently still iOS 6. But with the release of iOS 7, they will be ruining that fact, because iOS 7 doesn't seem to be compatible with iPod 4th Gen. And a lot of people own such a device.
Did I miss something, or is Apple going to wrong way?
