Sending Data between iPhone and iWatch

Question

The code below helps to get the data sent from iWatch to iPhone .But not from iPhone to iWatch if we write the code -(void)send:(NSString *)action and in Appdelegate

 (void)session:(nonnull WCSession *)session didReceiveMessage:(NSDictionary<NSString *,id> *)message replyHandler:(void(^)(NSDictionary<NSString *,id> *))replyHandler in wacth extension

In the watch extension controller

 -(void)send:(NSString *)action 
  {
    NSDictionary *request = @{@"request":action};
    [[WCSession defaultSession] sendMessage:request
      replyHandler:^(NSDictionary *replyHandler) {
     [self setTextForLabelWithData:[replyHandler valueForKey:@"response"]];
         }
     errorHandler:^(NSError *error) {
          NSLog(@"");
    }];
}

in Appdelegate

- (void)session:(nonnull WCSession *)session didReceiveMessage:(NSDictionary<NSString *,id> *)message replyHandler:(void(^)(NSDictionary<NSString *,id> *))replyHandler
  { 
    NSString *action = message[@"request"];
    NSString *actionPerformed;
    if ([action isEqual:@"foo"]) {
        // do "foo" stuff
        actionPerformed = @"foo done";
    } else if ([action isEqual:@"bar"]) {
        // do "bar" stuff
        actionPerformed = @"bar done";
    }
    replyHandler(@{@"actionPerformed":actionPerformed});
}

How can it be done ? Please help.

I guess you need to update the key from "response" at this line

 [self setTextForLabelWithData:[replyHandler valueForKey:@"response"]];

to "actionPerformed" to be like that:

 [self setTextForLabelWithData:[replyHandler valueForKey:@"actionPerformed"]];

You need to implement Watch Connectivity delegate method request to iPhone to Apple Watch and Apple Watch to iPhone.
