Xcode 9 - PTPusherErrorDomain error while subscribing to private channel

[kumarabhishek9]

I am using version ' 1.6.3' in Xcode 9 .
Whenever i try to connect to private channel in simulator for iOS 10/11 I am getting The operation couldn’t be completed. (PTPusherErrorDomain error 1.) in didFailToSubscribeToChannel

My code is as follows

self.client = [PTPusher pusherWithKey:someKey delegate:self encrypted:YES];
self.client.authorizationURL = [NSURL URLWithString:endpoint];
PTPusherChannel * channel = [self.client subscribeToPrivateChannelNamed:self.channelName];
    [channel bindToEventNamed:self.event handleWithBlock:^(PTPusherEvent *channelEvent) {
        NSLog(@"i am receiving");
    }];
    [self.client connect];

-(void)pusher:(PTPusher *)pusher willAuthorizeChannel:(PTPusherChannel *)channel withAuthOperation:(PTPusherChannelAuthorizationOperation *)operation {
     //code to generate token
    [operation.mutableURLRequest setValue:token forHTTPHeaderField:@"someField"];

- (void)pusher:(PTPusher *)pusher didFailToSubscribeToChannel:(PTPusherChannel *)channel withError:(NSError *)error {
    NSLog(@"didFailToSubscribeToChannel ----------------%@", error.localizedDescription);
}

Any idea why it's failing or did I miss anything ?

Is the endpoint that you're using accessible to your simulator device? Could it be that you're not using an HTTPS endpoint and haven't added an exception for it?

Perhaps you're not returning a valid auth body from your auth endpoint? What is your auth endpoint returning to the client?

I was finally able to solve the issue but i had to make a few changes .
1)

self.client = [PTPusher pusherWithKey:someKey delegate:self encrypted:YES];
 [self.client connect];

2. In connectionDidConnect function of the delegate

PTPusherChannel * channel = [self.client subscribeToPrivateChannelNamed:self.channelName];
self.client.authorizationURL = [NSURL URLWithString:endpoint];

When i tried to set authorizationURL before subscribing to channel I got error Existing subscription to channel
3) In willAuthorizeChannel function

NSMutableDictionary *mutableDict = [[NSMutableDictionary alloc] init];
   //set custom
    operation.customRequestParameters = [mutableDict copy];
