    }

    override func willActivate() {
        // This method is called when watch view controller is about to be visible to user
        super.willActivate()
    }

    override func didDeactivate() {
        // This method is called when watch view controller is no longer visible
        super.didDeactivate()
    }

}

Try cleaning your project. If that doesn't work, recreate any pod files that you may have created while making the project. Also, check if you have multiple outlets or actions for the same object.
