Swift 2 - Merge two arrays
<p>I am trying to merge two array:</p>

<p>array 1
<code>[["aaa","111"],["bbb","222"],["ccc","333"]]</code></p>

<p>array 2
<code>[["ddd","444"],["eee","555"],["fff","666"]]</code></p>

<p>What I want to achieve is to have a single array with the values respecting the array positions such as:</p>

<p>merged array
<code>[["aaa","111"],["ddd","444"],["bbb","222"],["eee","555"],["ccc","333"],["fff","666"]]</code></p>
