title: Can't add dictionaries with nil values to array in swift
body: <p>I am trying to create dictionary like here:</p>
  
  <pre><code>var dicItem = ["dataOfChange": 21-01-2012, "item": nil, "orderer": nil, "song": 1, "itemId": 3447, "petro": nil]
  </code></pre>
  
  <p>I create <code>dicItem</code> in a <code>loop</code> and in loop when create <code>dicItem</code> I want to add it to the array:
  <code>array.append(serStatdicItemusJSON)</code> <br/>
  This is my array:</p>
  
  <pre><code>var data = [[String:AnyObject]]()
  </code></pre>
  
  <p>But I am getting following error when try to add to array:</p>
  
  <pre><code>fatal error: attempt to bridge an implicitly unwrapped optional containing nil
  </code></pre>
  
  <p>I think that this is becouse of nil's but can't figure how to solve it.</p>
