Thanks @haozes. I had added that to my extension target by mistake instead of the app target.

The PTT functionality is designed to work like it does with the Apple Watch. If two users want to participate via PTT, they will both turn on the PTT functionality by joining the same channel in the app. Then that will give both phone A and phone B push tokens. Then either phone can send messages to the other. If phone A tries to send a message to phone B when it hasn't joined the channel, then your application server can send a push notification telling them that they missed a message.

When I run otool against the static library that we have created, it doesn't list any load commands. Therefore, I don't see LC_BUILD_VERSION or LC_VERSION_MIN_***. Why would there not be any "Load command" entries? I'm trying to build the Opus library from source so that it works with the simulator on Apple Silicon. When I use lipo I see that the two architectures are contained within the library. Lipo info: Architectures in the fat file: dependencies/lib/libopus.a are: x86_64 arm64

Do you know how the new "input-push-token": 1, option for iOS 18 changes the way that update tokens are handled?
