iOS WatchKit App won't avtivate "[WC] WCSession has not been activated"

[DennisBlah]

Hi all,

I've been busy with an iOS app with an watchkit app on it's side.
Basically it just pulls the UDID from the watch, and sends it over to the iPhone by a press on the button.

It did work, but since I changed to a new watch and phone and iOS updates it keeps giving me "[WC] WCSession has not been activated"
I've read somewhere to retry the activation after several seconds so I use an timer to do it for me after a second.

The Watch doesn't give any error, just no response on sendMessage. The message comes from the phone.
The watch is paired etc, I also receive my notifications and apps etc on my watch.

Anyone know whats going on here?

iPhone:

...
viewDidApear
checkWatch()
...

func checkWatch() {
        if (WCSession.isSupported()) {
            session = WCSession.default
            session.delegate = self;
            if(session.isReachable) {
                if(session.isComplicationEnabled) {
                    if(session.isPaired != true) {
                        NSLog("not paired")
                    } else if(session.isWatchAppInstalled != true) {
                        NSLog("Not installed on watch!")
                    } else {
                        session.activate()
                    }
                } else {
                    NSLog("Is not complication enabled!")
                }
            } else {
                NSLog("Session not reachable!?")
              
                let timer = Timer.scheduledTimer(withTimeInterval: 1.0, repeats: false, block: { timer in
                    print("CHECK WATCH AGAIN")
                    self.checkWatch()
                })
              
            }
        } else {
            NSLog("WatchConnectivty Not supported")
        }
      
    }

Apple Watch:

...
willActivate
if (WCSession.isSupported()) {
    NSLog("session supported..")
    session = WCSession.default
    session.delegate = self
    session.activate()
}
