Specify local tracks after connect room

[hungbv]

Hi everyone, I'm new to Twilio. I'm following document: https://www.twilio.com/docs/video/ios-getting-started I see that local media track must be created before connect to room:

let connectOptions = ConnectOptions(token: accessToken) { (builder) in
    builder.roomName = "my-room"

    if let audioTrack = localAudioTrack {
        builder.audioTracks = [ audioTrack ]
    }
    if let dataTrack = localDataTrack {
        builder.dataTracks = [ dataTrack ]
    }
    if let videoTrack = localVideoTrack {
        builder.videoTracks = [ videoTrack ]
    }
}

var room = TwilioVideoSDK.connect(options: connectOptions, delegate: self)

I want to connect to room first, then I will create and assign local tracks later. I didn't find any method to do it. Can I add local tracks after room is connected? how to do it?

@hungbv Yes, you can connect to a Room with no tracks, and publish them later. Also our APIs allow you to publish/unpublishing tracks once you are connected to a Room. See this code for example.
