Swift: Get the count of an array that includes subscripts : <p>I have an array of strings that have superscripts attached to each element. See the example below.</p>

<pre><code>var myArray = ["first": ["1", "2", "3"], 
               "second": ["4", "5", "6"], 
               "third": ["7", "8", "9"]]
</code></pre>

<p>Now all I want to do is get the count of elements, like <code>myArray.count</code> but this is throwing the error <code>Dictionary&lt;String, [String]&gt;.Index' does not conform to protocol 'Sequence'</code>. I'm guessing it's the superscripts causing the problem but I'm new to Swift so I don't know how to get around this and just count the top elements.</p>
