Hosts can activate or deactivate WXA before or during a meeting. With RTT SDK methods, users can control WXA to view live transcriptions.

To enable RTT:

1. Check to see if the Webex Assistant is enabled:

   var isEnabled = call.wxa.isEnabled
   

2. Verify that the user can control the Webex Assistant:

   var canControl = call.wxa.canControlWXA 
   

   

3. If the Webex Assistant is disabled, enable it:

   call.wxa.enableWXA(isEnabled: isWXAEnabled, callback: { success in
       print("setting WXA to: \(isWXAEnabled) operation returned: \(success)")
   })
   

   

4. Register for transcription updates:

   call.wxa.onTranscriptionArrived = { transcription in
       // ....
   }
