title: Swift Haneke: Json Data in TextView
body: <p>I used the Haneke Framework to get Data from a Site.
  With the Haneke Framework i also can get  Images from a site, and these Images i can present on a UIImageView.
  Now i wanted to get some text from a site.</p>
  
  <p>I did it like this: </p>
  
  <pre><code> cache.fetch(URL: URL).onSuccess { JSON in
              println(JSON.dictionary?["index"])
  </code></pre>
  
  <p>It printed me all the data from "Index".</p>
  
  <p>Now i want, that all the data from "Index" should be presented on a UITextView.</p>
  
  <pre><code>  self.textView.text = JSON.dictionary["index"]
  </code></pre>
  
  <p>But it doesn't work. I get the error: </p>
  
  <blockquote>
    <p>Cannot assign a value of type 'AnyObject' to a value of type 'String!'</p>
  </blockquote>
  
  <p>I have to unwrap it or? </p>
