So on WatchOS 2 that is possible !

You have to do on iPhone side :

First : 

import WatchConnectivity

Then :

   if WCSession.isSupported() { // check if the device support to handle an Apple Watch
        let session = WCSession.defaultSession()
        session.delegate = self
        session.activateSession() // activate the session

        if session.paired { // Check if the iPhone is paired with the Apple Watch
                // Do stuff
        }
    }

I hope It would help you :)

There is no built-in method (at least in the WatchKit SDK) to determine if a Watch has been paired with an iPhone. A common strategy is to write a BOOL to a shared NSUserDefaults (using app groups) so that the iPhone knows that the Watch app has been run at least once. That's the technique I've used in my own app.

If your code in your extension runs willActivate: on you controller then the Apple Watch is paired with the phone. Since you can't run any code on the actual Apple Watch there is no to know if the watch isn't paired with an iPhone.
