NSCocoaErrorDomain Error Code 4

This line of code I could not get to compile in S2 (yes it worked in 1.2):let newerDate = calendar.dateByAddingUnit(NSCalendarUnit.Day, value: 1, toDate: NSDate(), options: nil)The error message:Cannot invoke 'dateByAddingUnit' with an argument list of type '(NSCalendarUnit, value: Int, toDate: NSDate, options: nil)'Must be a bug.

Have tried 5 or 6 times now it install the beta package for 1474 on two diffrent computers. Each time the install freezes after about 10% and itunes pops and error code 14. I have tried diffrent cables and ports with no luck so far. I have tried redownloading the package to insure it wasnt corrupted but still no luck. It restores to 8.3 from both computers without trouble. I am unsure what to do from here. Has anyone else come across this and resolved it? Any suggestions as to what to try next? Your help is appreciated.
