Answer 1

For Xcode 6.1:

• Select your project
• In general tab, look for Linked Frameworks and Libraries (last one)
• Press + button
• Search MapKit.framework
• Finally add

Answer 2

For xCode 4.2:

Click on your project name ->targets ->building Phase ->link binary with library 
  -> click on + sign ->select mapKit.framework ->click add

Answer 3

I ran into this too, but I was able to get past it by following the instructions of step 2 in your link (thanks, by the way):

2. Add the MapKit framework to the project. (Control + Click Frameworks folder -> Add -> Existing Frameworks)

I just searched for MapKit.framework, added it to the project, and the error went away.

I haven't added any map code yet (although I do have a MapViewDelegate connected in IB), but it's working fine so far!
