Difference between += and append for adding single item to an Array?
<p>Going through the basics of Swift, I noticed that there are two ways of adding items to an array. </p>

<p>One way is using the <code>.append</code> method, another is using the <code>+=</code> operator (which allows for the adding of > 2 item arrays). </p>

<p>Is there any difference between using <code>+=</code> and <code>.append</code> when you only want to add a single item to the array? </p>

<pre><code>fooArray.append("Bar")
</code></pre>

<p>versus</p>

<pre><code>fooArray += ["Bar"]
</code></pre>
