How to cast from UInt16 to NSNumber

问题

I have a UInt16 variable that I would like to pass to a legacy function that requires an NSNumber.

If I try:

var castAsNSNumber : NSNumber = myUInt16

I get a compiler error 'UInt16' is not convertible to 'NSNumber'

Question

How can I recast this as an NSNumber?

回答1:

var castAsNSNumber = NSNumber(unsignedShort: myUInt16)
