Converting a NSAttributedString into a NSString using Swift

if you want to keep the atributted string simply use yourLabel.attributedText = atributedTtext

If you strictly want an NSString, not a String use the following:

let s = attributedString.string as NSString

Use the string property on NSMutableAttributedString:

var attributedString = NSMutableAttributedString(string: "hello, world!")
var s = attributedString.string
