What is the expected behavior when a user restarts their device without leaving a channel? I am testing this use case with my application and the system UI seems to be in a strange state. After the restart, the system PTT UI uses the name of my application for the channel title and instead of an icon, it uses the initials from my application name as the icon. It does not request a PTChannelDescriptor from my application. It appears that my application is not being called at all if I open the system PTT UI and try to send audio. Is this a known issue that I'm not handling properly or is this a bug with PTT?

I'm struggling with compiling lib opus so that it works in the simulator on Apple silicon. I found a thread on the forums that seems to address part of the issue, but I am unable to build the static lib so that it shows the platform it is targeting. The thread mentions that I should be able to run otool and see a "load commands" that indicate the platform. When I run otool against the static library that we have created, it doesn't list any load commands. I don't see LC_BUILD_VERSION or LC_VERSION_MIN_***. Why would there not be any "Load command" entries? % otool -l -arch arm64 dependencies/lib/libopus.a Archive : dependencies/lib/libopus.a dependencies/lib/libopus.a(bands.o): is an LLVM bit-code file dependencies/lib/libopus.a(celt.o): is an LLVM bit-code file dependencies/lib/libopus.a(celt_encoder.o): is an LLVM bit-code file dependencies/lib/libopus.a(celt_decoder.o): is an LLVM bit-code file ... dependencies/lib/libopus.a(mlp.o): is an LLVM bit-code file dependencies/lib/libopus.a(mlp_data.o): is an LLVM bit-code file The static library has the two architectures embedded in it, but when compiling the framework for the simulator platform the linking phase complains that we are building for the simulator, but linking object code built for ios. % lipo -info dependencies/lib/libopus.a Architectures in the fat file: dependencies/lib/libopus.a are: x86_64 arm64 In case you are curious, I'm just piggybacking on this project that has a build-libopus.sh script in the root directory that builds the official open source Opus library files. My hope is to build this static library for ios, ios-simulator, and mac-catalyst platforms and then include them in a xcframework.

I would like to know more about how I can use a bluetooth PTT device with the "Push to Talk" framework on iOS. I've enabled the setAccessoryButtonEventsEnabled on the PTChannelManager, but I am unable to get it to transmit when I press the PTT button on the device. Is there documentation that explains any additional steps I need to do in order to use a bluetooth PTT device with an iPhone using the Push to Talk framework? Our application works fine when interacting through the software UI. I'm testing with a PrymeMax PTT device. This is the user guide: https://www.pryme.com/files/manuals/MANUAL-BTH-550-MAX.pdf There are a lot of generic devices like this one that I would like to support. Can somebody provide more information on how this is accomplished? I would also like to support it with iOS versions older than iOS 17 if possible.

The documentation doesn't state how to get the new APNs push token that is associated with a Live Activity that is started via an APNs push notification. I have been able to get the new token by listening to all instances of the Live Activities for my attribute type, but it makes me wonder how the "input-push-token" option for iOS 18 is supposed to work. Is there another way to retrieve the newly created Live Activity push token when using "input-push-token"?

I'm unable to find sample code that demonstrates how to support a custom Live Activity layout for Apple Watch. I have read the documentation and have added the supplementalActivityFamilies with small and medium. However, I am not able to detect when the activityFamily is set to small. This is what I'm trying to use without success: struct MyWidgetLiveActivity: Widget { @Environment(\.activityFamily) var activityFamily: ActivityFamily var body: some WidgetConfiguration { ActivityConfiguration(for: MyWidgetAttributes.self) { context in if activityFamily == .small { Text("Apple Watch! \(activityFamily.description)") } else { Text("Not small family: \(activityFamily.description)") } } dynamicIsland: { context in return DynamicIsland { DynamicIslandExpandedRegion(.leading) { Text("Leading") } DynamicIslandExpandedRegion(.trailing) { Text("Trailing") } DynamicIslandExpandedRegion(.bottom) { Text("Bottom") } } compactLeading: { Text("CL") } compactTrailing: { Text("CT") } minimal: { Text("M") } } .supplementalActivityFamilies([.small, .medium]) } } This code shows "Not small family: medium" on my Apple Watch. Could somebody provide some insight into why this doesn't work for me?
