Xcode 5 with iOS 6 SDK: 'UIAccelerometer' is unavailable: not available on OS X

Question

I try to compile my app against the iOS 6 SDK under Xcode 5. I followed some tutorials how to use old iOS SDK's in Xcode 5: copy the SDK from an old Xcode (4.6.3) into Xcode 5.

Everything seems to be fine, I set the "Base SDK" to "iOS 6.1" and the "iOS Deployment Target" to "iOS 5.0" and download the iOS 6.1 simulator. But I get a lot of errors when I try to compile the app, like 'UIAccelerometer' is unavailable: not available on OS X

I don't want to build my app for OS X, only for iOS! I checked "Supported Platforms", but it is correcty set to "iOS".
