Hello Has anyone tried to send unreliable messages in first beta? I have a bad access crash every time I try: (lldb) thread backtrace * thread #28, queue = 'com.apple.root.user-initiated-qos.cooperative', stop reason = EXC_BAD_ACCESS (code=1, address=0x22)   * frame #0: 0x00000001033aa3b4 libdispatch.dylib`_dispatch_root_queue_drain + 208     frame #1: 0x00000001033aae6c libdispatch.dylib`_dispatch_worker_thread2 + 196     frame #2: 0x00000001f9b8d06c libsystem_pthread.dylib`_pthread_wqthread + 228 I don't know if I do something wrong or if someone else experiences the same issue. Thanks, Gil

This app was written using SwiftUI and I also consulted Apple's official documentation and some third-party websites. So I wrote something like the following code This is the Swift code where the player is called and the SharePlay-related logic import SwiftUI import AVFoundation import AVKit import GroupActivities import Combine struct EpisodeDetail: View { @State var episode: CommonResponse<Episode> @State var videoPlayer: CustomVideoPlayer @State private var groupSession: GroupSession<EpisodeActivity>? @State private var subscriptions = Set<AnyCancellable>() var body: some View { VStack { videoPlayer .transition(.move(edge: .bottom)) .edgesIgnoringSafeArea(.all) ScrollView { VStack(alignment: .center) { Button { prepareToPlay(episode.attributes) } label: { Label("SharePlay", systemImage: "shareplay") } .buttonStyle(.bordered) .cornerRadius(20) } VStack(alignment: .leading, spacing: 20) { Text(episode.attributes.title) .font(.title2) .fontWeight(.bold) Text(episode.attributes.description) .font(.body) .foregroundColor(.gray) } } .padding(12) } .task { for await session in EpisodeActivity.sessions() { configureGroupSession(session) } } } private func configureGroupSession(_ session: GroupSession<EpisodeActivity>) { groupSession = session videoPlayer.player.playbackCoordinator.coordinateWithSession(session) session.$state .sink { state in if case .invalidated = state { groupSession = nil subscriptions.removeAll() } } .store(in: &subscriptions) session.$activity .sink { activity in print("Activity Changed: \(activity.metadata.title ?? "No title for this ****** video LOL")") } .store(in: &subscriptions) session.join() } private func prepareToPlay(_ playerEpisodeData: Episode) { let activity = EpisodeActivity(episode: playerEpisodeData) Task { switch await activity.prepareForActivation() { case .activationDisabled: videoPlayer.player.replaceCurrentItem(with: AVPlayerItem(url: playerEpisodeData.videoUrl)) break case .activationPreferred: videoPlayer.player.replaceCurrentItem(with: AVPlayerItem(url: playerEpisodeData.videoUrl)) _ = try await activity.activate() case .cancelled: break @unknown default: break } } } } Then the following code is a custom AVPlayer import SwiftUI import AVFoundation import AVKit struct CustomVideoPlayer: UIViewControllerRepresentable { @State var videoUrl: URL var player: AVPlayer { return AVPlayer(url: videoUrl) } func updateUIViewController(_ playerController: AVPlayerViewController, context: Context) { playerController.modalPresentationStyle = .fullScreen playerController.allowsPictureInPicturePlayback = true playerController.canStartPictureInPictureAutomaticallyFromInline = true playerController.player = player } func makeUIViewController(context: Context) -> AVPlayerViewController { return AVPlayerViewController() } } The SharePlay prompt pops up properly and shows the current activity correctly This is a screenshot of the SharePlay pop-up box, I couldn't insert an image, so I had to insert a link https://i.stack.imgur.com/QNqBE.jpg But when I do something with the player, like pause, or adjust the playback progress, the other iPhone doesn't sync So what should I do? Can't thank you enough :-)

The GroupSession API doesn't seem to expose any method for determining whether there is active FaceTime call. Any suggestions on how one might check this? (I can't use groupSession.activeParticipants, as this data is only available once a SharePlay session has started. I need to know the existence of a FaceTime call prior to the user starting a SharePlay session).

I'm trying to make an app for iMessages and Facetime that allows users to upload custom Animojis based on 3d Files. Is this possible? I'm running into troubles and could really use some help from my fellow devs. Thanks, Ryan

Since iOS 15, the UI for FaceTime has been moved to the upper half of the screen. I find this choice strange considering they did the exact opposite for Safari in this exact update. (Moved it from the top to the bottom.) Are there any options or is there any way to revert the changes made to that specific thing within FaceTime?

In the same way you can make "GamePidgeon" for iMessages, is a programmer able to integrate custom applications and games into FaceTime? Thanks, and all the best, Wuz

Hi everyone, I am not able to get Group Activities (SharePlay/mediaSession.coordinator) to work on Safari. Here's my setup: macOS Monterey 12.3 Beta, Safari 15.4, Intel. https://github.com/tokorom/SharePlaySample as the iOS project. (I also experimented with setting metadata.type = .watchTogether.) I set https://theoplayershareplay.thijslowette.repl.co as the fallbackURL. (Code available at https://replit.com/@THIJSLOWETTE/THEOplayerSharePlay.) What am I doing & seeing? I Facetime myself from an iOS 15.2.1 as the "initializer" to my macOS through the Desktop Facetime app. I open the app on my iOS device. I start the SharePlay activity. I can see the "popup" on my macOS device. I click open, and it opens up my fallback URL in Safari. (I had to set Safari as my default browser.) I can see (in the Safari dev tools) that my Safari has joined the session. In Safari, I click the custom play button at the top which should call coordinator.play(). Nothing happens on my iOS app. I pause the video again in Safari. I hit play in my iOS app. Nothing happens in Safari. You can verify these observations in the screen recording at https://www.loom.com/share/809062d87af244b1bda96d30bd08518e. Notes Also tried different SharePlay projects. Also tried Facetiming other people's macOS to ensure that the session is between two unique Facetime IDs. Also tried the macOS 12.2 Stable. Although I'm running out of ideas, I am not yet ready to give up. Can someone assist? I promise I'll write a kick-*** how-to guide & demo for the community if we figure it out! 😅🙌 Kind regards, -thijsl

I know that Apple is very aware of privacy concerns. Do Share Play and Group Activities comply with GDPR's legal rules? What kind of servers (e.g. geography) are involved to manage the connection? Thanks Lars

I'm working on Group Activities for our video app. When I start a video from Apple TV, it's fine to sync it with other user's iPhone device. but inverse case, it's not working. And in some cases, I saw "Unsupported Activity : The active SharePlay activity is not supported on this Apple TV" What did I miss or wrong something?

Details I'm working on a video streaming app, and we've implemented GroupActivity for SharePlay. The app doesn't support PiP. Based on the documentation we found, we can use the function requestForegroundPresentation described here. I was trying to call this function when the GroupSession is in waiting and joined states, but nothing happens on the user's device. There is no banner to explain anything The WWDC videos doesn't show an example, they just mention this feature, and it's unclear how it should work. Tried the api in the sample project supporting_coordinated_media_playback, and same result

I was hoping to add support for SharePlay, but my app is not Universal, because it is around 5 years old. The macOS and iOS versions have different bundle ids, and making a universal app would be a bag of hurt (loss of reviews, migrating data in sandboxed environments and lots more). Am I correct that SharePlay will only work with a single bundle id? I was hoping by simply choosing the same activity type in each app they could connect, but I don't really see how it can given the activity type is hard coded, rather than configured in the Info.plist. If this is the case, it seems like a lost opportunity, not only for "legacy" apps like ours, but also for anyone who might want to work between apps in an app group. Presumably rather than hard coding the activity type, it could have been registered as an Info.plist configuration or entitlement, allowing apps to partake with different bundle ids, the same way it works for iCloud for example.

Hi there, when awaiting a message through an GroupSessionMessenger, I can get the Participant who sent the message through the context.source. But is there any way to get the actual name of that Participant? I haven't seen any way - but I guess it would have to go through the Contacts API? The reason I need this is because of the VoiceOver support in my app. If a Participant triggers an interaction, I would like to announce who triggered the interaction instead of just announcing "Someone did XY". Best, Klemens

I am using SharePlay and the Group Activities framework in my app and my usecase requires the number of participants, so I am trying to get it like this: _ = SharePlayManager.sharedInstance.groupSession?.$activeParticipants.sink(receiveValue: { participants in             print(participants.count)         }) But this always prints 0, am I doing something wrong? (groupSession is 100% not nil)

I'd like to know if there is a way to limit the number of participants in a group activity (SharePlay). Looking through the API, I could not find anything regarding limiting or requiring the number of participants.

Is a fix in the works to give us access to Full Screen on Mac OS Monterey during a FaceTime call?

I want to make a custom UI that integrates each video feed from my FaceTime group activity participants. I found the app Share+ in the App Store integrates the video from each FaceTime participant into it's own UI, so I know it's possible. Can anyone point me to the relevant documentation that shows me how I can get to the video of each FaceTime group member to put in my own AVSampleBufferDisplayLayer or otherwise?

I have the SharePlay button on my FaceTime but it is grey and does nothing when I click on it.

I was wondering if one can create an interface that allows a user to enter a youtube video and have it sync across different users using shareplay?
