title: ios swift proper float to string conversion
body: <p>So in Obj-c this would be done differently, but I was wondering if anyone had any idea how to do this in swift? I feel embarrased having to ask this, but simply cannot find any documentation on it, how do I convert a float to string? </p>
  
  <pre><code>override func viewDidLoad() {
      super.viewDidLoad()
  
      var userScore = receivePlayerCard?.playerScore
  
      var convertUserScoreToString: Float
  
      scoreNameLabel.text = convertUserScoreToString //need to convert it to a string here
      scoreNameLabel.textColor = UIColor.whiteColor()
      // Do any additional setup after loading the view.
  }
  </code></pre>
