The camera for the first user is not appearing, only after another user joins

[ArthurHenriqueVieira]

Hello!

I've been having this problem where when I start a channel, my camera icon is not appearing, only when another user joins in the channel, for some reason my user camera appears:

my code:

ScrollView(.vertical, showsIndicators: false) {
                VStack(spacing: .zero) {
                    ForEach(Array(users), id: \.self) { uid in
                        AgoraVideoCanvasView(manager: dependencies.watchPartyScene.getManager(), uid: uid)
                            .aspectRatio(contentMode: .fit)
                            .cornerRadius(2.ds.quants)
                            .clipShape(Circle())
                            .allowsHitTesting(false)
                    }
                }
                .padding(4.ds.quants)
            }

and I add users and remove them using the delegates:

public override func rtcEngine(_ engine: AgoraRtcEngineKit, didJoinedOfUid uid: UInt, elapsed: Int) {
        var users = allUsers
        users.insert(uid)
        userUpdate.send(users)
    }

    public override func rtcEngine(_ engine: AgoraRtcEngineKit, didOfflineOfUid uid: UInt, reason: AgoraUserOfflineReason) {
        userUpdate.send(allUsers)
    }

try making sure that the local user is added to the set on the main thread, sounds like that kind of issue.

[ArthurHenriqueVieira]

I've made sure it's running on the main thread, no use.

Also, if I add this code:

public override func rtcEngine(_ engine: AgoraRtcEngineKit, didJoinChannel channel: String, withUid uid: UInt, elapsed: Int) {
            var users = allUsers
            users.insert(uid)
            userUpdate.send(users)
        }

Not only it doesn't appear when joining the channel created, when another user joins he doesn't appear also.

the bizarre thing is, even if I hardcode the uid, it doesn't appear:

ScrollView(.vertical, showsIndicators: false) {
                VStack(spacing: .zero) {
                    ForEach(Array([UInt(9)]), id: \.self) { uid in
                        AgoraVideoCanvasView(manager: dependencies.watchPartyScene.getManager(), uid: uid)
                            .aspectRatio(contentMode: .fit)
                            .cornerRadius(2.ds.quants)
                            .clipShape(Circle())
                            .allowsHitTesting(false)
                    }
                }
                .padding(4.ds.quants)
            }

There's a bit too much unknown here, here's some debugging pointers though

• have you managed to follow the SwiftUIRtc guide and get it working?
• here's a basic example using it: https://github.com/AgoraIO-Community/Agora-ActiveFence-iOS/blob/main/Agora-ActiveFence-iOS-Demo/ContentView.swift
• Are you using ObservedObject for the manager or is that dependencies.watchPartyScene.getManager() function returning the same manager?
• Check how many times is the AgoraVideoCanvasView created in your scenario? It might be making it too many times there

If you're still having trouble, dial the implementation back to the examples in SwiftUIRtc, then add pieces from your code back in.

Here's further docs on SwiftUIRtc: https://agoraio-community.github.io/SwiftUIRtc/documentation/swiftuirtc/

Also try using the debug view hierarchy tool in Xcode.

We have many comprehensive examples using SwiftUI here: https://github.com/AgoraIO/video-sdk-samples-ios
