You need to add EventKit as a framework to your project.

To do that, go to your project's settings and click on the the "Build Phases" tab. You should see something like this:

Click on the "+" button to add new frameworks.

And scroll down and you should see and add "EventKit.framework". You might also need to add "EventKitUI.framework" (it likely wouldn't hurt even if it wasn't needed).
