if the Model wants to communicate with the controller, is KVO the only way?
And have we used this in the Checklist project?

Hi @feanor, KVO is one way approach to communicating when the state of another object changes but you can also use notifications and delegates. I don’t believe KVO is used in the checklist project but rather the delegate pattern.

Best,

Do you know any good place where I can learn how to use KVO?
All the best
