Error: Prototype Cells Must Have Reuse Identifiers

I am running the latest version of Xcode5 and the iOS7 simulator. At the end of this lesson when I go to run my app I get the error (yellow triangle) "Prototype Cells Must Have Reuse Identifiers" and in the simulator I get a black screen.

Adding the term "Cell" in the Table View Cell Identifier field for the three cells removed the yellow warning, but when I run in the simulator the screen is still black.

What steps should I take at this point?

I downloaded the iOS6 simulator and ran the app in that, but the screen is still black in the simulator.

I figured out the solution to my issue in the Instructors notes:

"Teacher's Notes Updates

In Xcode 5 we set the storyboard for an app using the "Main Interface" field. The "Main Storyboard" field in the video is no longer available."
