About iOS Screen Share didn't work.

[107360111]

Hello everyone, here is a question about broadcast.

According to the description of iOS Screen Sharing on Wiki, I have followed the instructions to set up the broadcast. Here are the App Groups and SampleHandler after setup:

App Groups:

Sample Handler:

Additionally, I have enabled the broadcast permission in the Room settings. I am using the following code to receive the localParticipant and remoteParticipant:

Room Initialization:

Control Screen Share Function:

Get Local Participant: [room(_ room: Room, participant: LocalParticipant, didPublishTrack publication: LocalTrackPublication)]

Get Remote Participant: [room(_ room: Room, participant: RemoteParticipant, didSubscribeTrack publication: RemoteTrackPublication)]

When I first press the screen sharing button, a prompt window like the one in the picture appears. After I press "Start Recording", the screen recording starts. However, in the function room(_ room: Room, participant: LocalParticipant, didPublishTrack publication: LocalTrackPublication), I did not receive the video track that I sent out. Also, in the function room(_ room: Room, participant: RemoteParticipant, didSubscribeTrack publication: RemoteTrackPublication), I did not receive the event of subscribing to my own video track.

Local Participant Start Recording:

Remote Participant Didn't Get Local Participant's screen share video track:

Local Participant Stop Recording:

Please help me to solve this question, thank you very much.

I needed to add RTCAppGroupIdentifier to both app and broadcast extension info.plist

This example didn't work on my side too even it set the RTCAppGroupIdentifier correctly. https://github.com/livekit-examples/swift-example/blob/main/iOS/Info.plist#L47 https://github.com/livekit-examples/swift-example/blob/main/iOS/BroadcastExt/Info.plist#L32

@mokuzuu does it works after you added the RTCAppGroupIdentifier to your project? would you mind confirm this LiveKitExample.xcodeproj is working or not on your side?

turns out the example was using this plist https://github.com/livekit-examples/swift-example/blob/main/Multiplatform-Info.plist and it didn't have the RTCAppGroupIdentifier

Hello, may I ask why my application encounters an error timeout when using screen sharing for re signing and distributing enterprise certificates after using a paid developer account to create a test package? However, during normal local testing, screen sharing works normally.

Same situation. Is there some solution?

The issue with the example plist missing RTCAppGroupIdentifier was resolved in https://github.com/livekit-examples/swift-example/pull/51, which I think was the main issue here with the original report

@WangDaShuai1020 @BasinPhoto please open new issues with more details about what you're seeing if they are still unresolved (but check latest SDK releases, a few fixes have gone in)
