title: What exactly are those data types int 16, int 32 and int 64 on the iPhone, in Core Data?
body: <p>The Xcode data modeler shows me those three different int data types. When I would write code, which data types do these really correspond to on the iPhone? Are they all simply NSInteger, wrapped in an NSNumber?</p>
  
  <p>As far as I see it, NSNumber only differentiates between int an NSInteger... so I guess those three end up beeing pretty much the same?</p>
