GameKit / GameCenter - I386

I am having difficulty with iOS GameCenter. I am following some youtube tutorials, but as soon as I finish the code I get this error:

It looks like you have not added a GameKit framework to your project.

If you are using Xcode 3.2.x:

  • Right-click a group Frameworksin the file tree (to the left of the xcode window)
  • Press Addand then selectExisting Frameworks...
  • Scroll to GameKit.frameworkand double-click on it.

If you are using Xcode 4:

  • In the file tree, click on the project (item at the top)
  • Choose a target
  • Go to the tab Build Phasesin the main panel
  • Expand Link Binary with Libraries
  • Press button +
  • GameKit.framework .
