Communicating between Apple Watch and iPhone

Question

I am making a to-do list application. I also made a watchOS extension for it. Now, the user can add/remove to-dos both on the Apple Watch and the iPhone. I need a way to communicate the to-do list array between the watch and the iPhone. I understand that I would need to use WCSession, and send messages to one-another. But I could not find any good tutorials on this.

//On the watch
- (void)toDosWereUpdated{
  //Send data to phone
}

//On the phone
- (void)toDosWereUpdated{
  //Send data to watch
}

Could someone please provide me with some explanation and/or sample code?

Thanks!

You can check how to use WCSession in this great repository: https://github.com/grachyov/Reminders-on-Apple-Watch

It's an open source Apple Watch app which is actually to-do list too.
