Is iOS 64-bit simulator really 64-bit?

Question

According to Major 64-Bit Changes int & long sizes are 4 and 8 bytes. But when I run on iOS 64-bit simulator with following code:

NSLog(@"NSInteger size: %i", sizeof(NSInteger));
NSLog(@"int       size: %i", sizeof(int));
NSLog(@"long      size: %i", sizeof(long));

The output is

  NSInteger size: 4 int size: 4 long size: 4 

So, the sizes tell us another. What's output on real device?

Yes, the simulator is 64-bit. You get this output because probably your app is not compiled for 64-bit. In your project settings select the following (including 64-bit)
