Not able to login via SwiftUI app

[riverbaymark]

I have been trying to implement RTM in a SwiftUI app but it keeps giving me an error code 3. Below is the code I am currently using (I instantiate the class as a @StateObject and pass the instance back to represent the rtm and channel delegates)..

`class AgoraChatOO: NSObject, ObservableObject {

@Published var chatMessages: [ChatMessage] = []
@Published var kit: AgoraRtmKit?
@Published var rtmChannel: AgoraRtmChannel?

func updateKit(appId: String, delegate: AgoraRtmDelegate, channelDelegate: AgoraRtmChannelDelegate) {
    
        kit = AgoraRtmKit(appId: appId, delegate: delegate)
    
        
        guard let kit = kit else { return }
     
    kit.login(byToken: "my_tokeni", user: UIDevice.current.name) { [unowned self] (error) in
        
            if error != .ok {
                print("Error logging in: ", error.rawValue)
            } else {
                self.rtmChannel = kit.createChannel(withId: "testChannel", delegate: channelDelegate)
                
                self.rtmChannel?.join(completion: { (error) in
                    if error != .channelErrorOk {
                        print("Error joining channel: ", error.rawValue)
                    }
                })
            }
        }
    }

}`

Login error code 3 means that there's an invalid parameter. It's likely either the appId or UIDevice.current.name.

Could you print out what that UIDevice name is? Not all characters are allowed there, and there's a limit of 64 bytes:

Hi @maxxfrazer you were absolutely correct..I changed it to a different string and it worked. Did have a couple of other issues pop up though. I could not get it to logon using a token, but was able to with a nil token using a different AppId. The other issue now is the delegate methods are not being called after sending a message to the channel. Would it be possible for you to create a simple SwiftUI demo for RTM (sorry I know it's a big ask). Also wanted to say I'm a big fan of your Agora and RealityKit tutorials and articles.
