Model key paths problem/ question


Hello there,

I have the raise man application up and running fine and have managed to complete challenge 1, however, while looking i noticed something odd. The the Model Key Path box for my array controller where i typed employees has a round grey icon in it with a ! in. When i hover my mouse over this icon a message pops up that reads “xcode cannot resolve the entered keypath”. It is the same for the boxes in the table columns where i types personName and expectedRaise.

This seems odd as the application works fine when in run it. Anyone have any idea what is going on here? I have had a look for something but i have not been able to work it out.
