Based on the behaviour I am seeing, I assume the PTT framework rejoins an existing channel between app launches unless leave is explicitly called? And to update on the foreground transmitting, I am still getting the channelNotFound error even though I am requesting transmission in the didJoinChannel delegate function.

Yep spotted my mistake with the foreground transmitting, but background transmitting doesn't seem to be working in iOS beta 1. To replicate: Join a channel Background the app Press the blue pill in the top left to bring up the PTT system UI Pressing the transmit or leave channel button does not fire any of the delegate callbacks When you foreground the app, the delgate callbacks fire

Adding requestBeginTransmitting inside a delay seems to get rid of the error. This seems odd?

Just got out of a WWDC lab with some of the siri/intents engineers. Seems like I needed to use the EntityStringQuery protocol over the EntityQuery which allows me to implement entities(matching string: String). This gives me the string that Siri hears and allows me to return an entity of my choosing.

Just out of a WWDC lab with some folks on the team. Seems to just be a UX thing in the Shortcuts app. When using EntityQuery in the shortcuts app you are presented with a context menu to use a variable, when using EntityStringQuery you need to press and hold the parameter to open the context menu. Also in iOS 26, the system seems to be able to use suggestedEntities to match a string from siri FYI
