WatchOS 2.0: WCSessionDelegate not get called (in Simulator)

I am running WatchOS 2.0 on Version 7.0 beta 5. I am running an iOS with iWatch App.

I setup the Targets as shown.

I had my iOS's ViewController and WatchKitExtension's Interface Controller both activated WCSession and set as delegate.

if ([WCSession isSupported]) {
    WCSession *session = [WCSession defaultSession];
    session.delegate = self;
    [session activateSession];
    NSLog(@"iOS App WCSession is supported");
}

Then I tried to send userInfo from Watch to iOS :

NSDictionary *userInfo = [[NSDictionary alloc]initWithObjectsAndKeys:@"testingURL", @"outputURL", nil];
        [[WCSession defaultSession] transferUserInfo:userInfo];

But my ViewController's delegate method never get called:

- (void)session:(WCSession *)session didReceiveUserInfo:(NSDictionary<NSString *,id> *)userInfo{

dispatch_async(dispatch_get_main_queue(), ^{
    NSLog(@"Received userInfo Transferr");
    NSLog(@"%@", userInfo);
    [self.label setText:@"Received"];
});
}

I was running the Watch App and iOS together from Simulator by pressing Run here from this scheme:

Could anyone please tell me what did I do wrong?
