ios - Using a Swift String with NSData without NSString -

-

is possible init swift string (not nsstring) contents of nsdata object without creating nsstring first?

i know can use nsstring:

var datastring = nsstring(data data: nsdata!, encoding encoding: uint)

but how can use basic swift string type? thought swift strings , nsstrings interchangeable, have data out of nsdata using nsstring , assign value swift string?

as of swift 1.2 aren't quite interchangeable, convertible, there's no reason not use nsstring , constructors when need to. work fine:

var datastring = nsstring(data:data, encoding:nsutf8stringencoding) as! string

the as! needed because nsstring(...) can return nil invalid input - if aren't sure data represents valid utf8 string, may wish use following instead return string? (aka optional<string>).

var datastring = nsstring(data:data, encoding:nsutf8stringencoding) string?

once constructed, can use datastring other swift string, e.g.

var foo = datastring + "some other string"
