Adding First and Last Name to an Alert?

As it stands right now, I am able to add a Name to Core Data and I am able to retrieve the Name.
What I am trying to do, is add a First and Last name in the Alert Window.

And second I am having difficulty in configuring the Cell for SubTitle

Can someone please help me

To add any text to an alert window you must include it in the alert’s title or message, depending on where you want it to appear.

As for the cell subtitle, you need to choose a right detail type cell as defined by UITableViewCellStyleSubtitle as you can see here:
