GoogleCast iOS sender, v4, not sending messages

Question

On version 2, the sender app was able to send messages.

func deviceManager(_ deviceManager: GCKDeviceManager!,
didConnectToCastApplication
applicationMetadata: GCKApplicationMetadata!,
sessionID: String!,
launchedApplication: Bool) {
  deviceManager.add(self.textChannel)
}

However, the API says that we are now using GCKSessionManager instead of GCKDeviceManager.

The API says I must have a GCKSession add the textChannel, which I did here: Once the session starts, I add the textChannel (because sessionManager.currentCastSession was nil before the session started).

func sessionManager(_ sessionManager: GCKSessionManager, didStart session: GCKSession) {
    if session.device == connectionQueue {
        connectionQueue = nil
    }
    self.sessionManager!.currentCastSession!.add(textChannel)
    print("")
}

Meanwhile, I send the text message in another function:

let result = self.textChannel.sendTextMessage("\(self.textField.text)", error: &error)

But the result is always false, and the error is always "Channel is not connected or is not registered with a session". In addition, when I do:

print("isConnected1 \(self.textChannel.isConnected)")

the result is false. Do you know what other steps I am missing for it to be connected?

Just learned that it was an issue of my namespace. It connects now. Problem was the namespace wasn't matching the namespace from my receiver code.

fileprivate lazy var textChannel:TextChannel = {
return TextChannel(namespace: NAMESPACE)
}()

Hi, I encounter the same issue, how do you get the namespace of currentCastSession so that it will match? – Luthfi Rahman Feb 06 '19 at 02:22
Looks like in my index.html for my receiver app, I had this line: window.messageBus = window.castReceiverManager.getCastMessageBus( NAMESPACE); – PhoenixB Feb 06 '19 at 05:27
Also, the generic namespace name is 'urn:x-cast:com.google.cast.sample.helloworld' – PhoenixB Feb 06 '19 at 05:33
is the generic namespace always like that? – Luthfi Rahman Feb 06 '19 at 06:48
Not sure but I guess it is that way, and that default receivers have that set as their namespace – PhoenixB Feb 07 '19 at 23:47
