EXC_BAD_ACCESS

[itsoulos]

I have bridged my app with the library but it gives me the following error constantly

Thread 1: EXC_BAD_ACCESS (code=1, address=0xfffffff9fffbd2ce)
at this line

                 .withLogging(minLogLevel: .debug)

on this code
self.chatHubConnection = HubConnectionBuilder(url: URL(string: self.url)!)
.withLogging(minLogLevel: .debug)
.withAutoReconnect()
.withHttpConnectionOptions(configureHttpOptions: { (httpConnectionOptions) in
if let header = self.headers {
for (key, value) in header {
httpConnectionOptions.headers[key] = value
}
}
})
.withHubConnectionDelegate(delegate: self.chatHubConnectionDelegate!)
.build()

There must be more to the story that is not included here. I don't think the information provided allows to tell what's going on. The client is not allocating memory by itself or dealing with pointers. Here are some details on how to debug EXC_BAD_ACCESS:

• https://loufranco.com/blog/understanding-exc_bad_access,
• https://stackoverflow.com/questions/19183555/thread-1-exc-bad-access-code-1-address-0xf00000c.

I am not sure if I can do more - the line you pointed to is being used in many tests and I have never seen EXC_BAD_ACCESS on this line.

The client is starting through Objective C using the following code

signalrswift= [[SignalRSwift alloc ] initWithUrl:signalRString port:self.signalrPort hub:self.signalrHub functionName:self.signalrMessageFunction headers:params];
               
        [signalrswift signalROpenWithBlockfunc: ^(
                                                  NSString * _Nonnull sender,
                                                  NSString * _Nonnull message) {
            NSLog(@"Sender %@ Message %@",sender,message);
            if(self.delegate!=nil)
                [self.delegate onSignalrMessageWithUser:sender andMessage:message];
                 }];

and the client has the following function:

    @objc public func signalROpen(blockfunc:funcBlock!){
      
        self.chatHubConnectionDelegate = ChatHubConnectionDelegate(signalrswift: self)
       
        self.chatHubConnection = HubConnectionBuilder(url: URL(string: self.url)!)
                     .withLogging(minLogLevel: .debug)
                     .withAutoReconnect()
                   .withHttpConnectionOptions(configureHttpOptions: { (httpConnectionOptions) in
                                  if let header = self.headers {
                                      for (key, value) in header {
                                          httpConnectionOptions.headers[key] = value
                                      }
                                  }
                              })
                     .withHubConnectionDelegate(delegate: self.chatHubConnectionDelegate!)
                     .build()
        
        
  self.chatHubConnection!.start()
        self.chatHubConnection!.on(method: self.functionName, callback: {(sender: String, message: String) in
            print("Receive: \(message)")

                blockfunc(sender,message)
           })
        
    
        
        self.chatHubConnection!.on(method: "BroadcastMessage", callback: {(sender: String, message: String) in
            print("Broadcast: \(message)")
               })
 }

Unfortunately, I have never tried using the client from Objective-C. There are a couple issues on Objective-C integration (#37, #13) which contains some advice from people who were able to make it work. Hopefully, they will help you get unblocked.

There is no pending action item for this scenario so I am closing this issue.
