This:
UIDevice *theDevice = [UIDevice currentDevice];
NSLog(@“%s NSUInteger %lu bytes on %@“,__FUNCTION__,
sizeof(NSUInteger), theDevice.localizedModel);
prints:
-[AppDelegate application:didFinishLaunchingWithOptions:] NSUInteger 4
bytes on iPhone (iPone 4s in Simulator)
-[AppDelegate application:didFinishLaunchingWithOptions:] NSUInteger 8
bytes on iPad (iPad Air in Simulator)

With DNS_BUILD_32_LIKE_64 NSUInteger is long on all platforms, so %lu works in
all cases.
Kind regards,
