How to put alphabetical index on right side of a UITableview
<p>I'm using Xcode 8 and Swift 3. I would like to create a dynamic <code>UITableView</code> to hold customer names with an alphabetical index letters or tabs on the right side for quick navigation. </p>

<p>I have found info on how to create the dynamic <code>UITableView</code>, so I'm good there, but haven't found any info on how to the alphabetical indexing.</p>

<p>Could someone please provide some information on how to do the indexing on a <code>UITableView</code>? </p>
