Is it possible to init a Swift string (not
var datastring = NSString(data data: NSData!, encoding encoding: UInt)
As of Swift 1.2 they aren't quite interchangeable, but they are convertible, so there's really no reason not to use
NSString and its constructors when you need to. This will work fine:
var datastring = NSString(data:data, encoding:NSUTF8StringEncoding) as! String
as! is needed because
NSString(...) can return
nil for invalid input - if you aren't sure that the data represents a valid UTF8 string, you may wish to use the following instead to return a
var datastring = NSString(data:data, encoding:NSUTF8StringEncoding) as String?
Once constructed, you can then use
datastring just like any other Swift string, e.g.
var foo = datastring + "some other string"
