Apple Watch Connectivity framework

Previously, before WatchOS 2 it was very hard for your apple watch and iPhone to communicate but with WatchOS 2 and the new Watch Connectivityframework it seems to have improved a lot.

What I am wondering is that with this new framework, is there an easy way for me to run a function on the parent app on the iPhone by clicking a button on the apple watch. Before you would have to use wormhole and it was very confusing.

Basically all I want is to press a button on my watch, and it'll run a line of code on my iPhone!

Any help would be greatly appreciated!

You can use sendMessage API

1) Call sendMessage method by clicking a button on the apple watch.

WCSession.defaultSession().sendMessage(applicationDict,
   replyHandler: { ([String : AnyObject]) → Void in
      // Handle reply
   })
   errorHandler: { (NSError) → Void in
      // Handle error
});

2) didReceiveMessage method is called in your iPhone

func session(session: WCSession, didReceiveMessage message: [String : AnyObject], replyHandler: ([String : AnyObject]) -> Void) {
    // send data to Apple Watch
    replyHandler(["retrievedData" : data])
}

Good luck!

For this you would want to use the WCSession's sendMessage API which will wake the iOS app up if necessary to deliver the message

If you look in the Apple WCSession you can find all the necessary to create a direct message from a device to the other.
