title: Storing an array in a Firebase Database
body: <p>I am trying to store an array in the Firebase Database, but I'm not sure how to do it properly.</p>
  
  <p>I am wanting to store an array such as:</p>
  
  <pre><code>var exampleArray = ["item1", "item2", "item3"]
  </code></pre>
  
  <p>The reason why is I populate a UIPicker with values from an array, and rather than having to push an update to the app each time to add a new value, it would be better if I could just update the database and instantly add the new value to each app.</p>
  
  <p>Is there any way that I could store the values in the database and pull the values from the database and store it into an array as shown above?</p>
  
  <p>Thank you.</p>
