title: Appending strings into an array in Parse
body: <p>I just learned how to store an array into a Parse Cloud using the example provided by the Parse Documentation:</p>
  
  <pre><code>gameScore.addUniqueObjectsFromArray(["flying", "kungfu"], forKey:"skills")
  gameScore.saveInBackground()
  </code></pre>
  
  <p>Now, utilizing this logic, I want to append strings into the array. So this is what I wrote:</p>
  
  <pre><code>@IBAction func requestButtonPressed(sender: AnyObject) {
      var prayerRequests = PFObject(className: "PrayerRequests")
      prayerRequests.addObject(["YOIDJFO"], forKey:"skills")
      prayerRequests.saveInBackground()
  }
  </code></pre>
  
  <p>Now, after having executed the function <code>requestButtonPressed</code> three times, in parse this is happening: </p>

  <p>However. I don't want that to happen when I execute the function <code>requestButtonPressed</code> three times. I want it to be something like this:</p>
  
  <p><a href="https://i.stack.imgur.com/QFsJP.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/QFsJP.png" alt="enter image description here"></a></p>
  
  <p>Anybody have a solution to this problem?</p>
