You can use this method to send notification to ios App to make request
[[WCSession defaultSession] sendMessage:dictSendMessage replyHandler:^(NSDictionary<NSString *,id> * _Nonnull replyMessage) {
} errorHandler:^(NSError * _Nonnull error) {
}];
And you can receive that notification with this delegate method in ios app
-(void)session:(WCSession *)session didReceiveMessage:(NSDictionary<NSString *,id> *)message replyHandler:(void (^)(NSDictionary<NSString *,id> * _Nonnull))replyHandler
{
}
Note : You can also request to server from watch app it self with the help of
NSURLSessionDataTask *taskDownload = [[NSURLSession sharedSession] dataTaskWithURL:url completionHandler:^(NSData *data, NSURLResponse *response, NSError *error)
{
}];
// Start the task.
[taskDownload resume];
