If you're using Swift, you can just overload the + operator so that you can concatenate them in the same way you concatenate normal strings:

// concatenate attributed strings
func + (left: NSAttributedString, right: NSAttributedString) -> NSAttributedString
{
    let result = NSMutableAttributedString()
    result.append(left)
    result.append(right)
    return result
}

Now you can concatenate them just by adding them:

let helloworld = NSAttributedString(string: "Hello ") + NSAttributedString(string: "World")
