Implicit bridging has been reduced

Available from Swift 1.2

Prior to Swift 1.2 bridging from Objective-C types to Swift types happened implicitly, meaning that you could use the two interchangeable. From Swift 1.2 onwards you must now use as to typecast these yourself. For example:

authenticateUser(yourNSString as String)

Note

This has changed in later versions of Swift – implicit bridging never happens now.
