Hello.

I am working on adding support for iOS 13. Previously the app has been able to record audio for transmition while in the background when the user presses an external button, such as one from a wired headset. This is important as many users such as first responders are currently able to talk by pressing a button, rather than pulling the phone out of a pocket, unlocking it, launching the app etc.

I can't find any sort of recording in the background permission to put in the info plist. Are there any special categories or options needed in the Audio Session to permit this on iOS 13? Failing that, is there a way to launch the app when the user presses the button ( wired or bluetooth le) so the recording can start?

How does the Messages App allow recording on the notification? Inter-App Audio?

Thanks.

Thanks I will update our feedback with a reference to this id @k.alonso: what response did you get? Can you share it and what id? I read that there is a security issue in 12.4 and that 12.4.1 is expected. I hope this issue will get some focus also. Kind regards Jens

Did anyone test with 13.1 developer beta 1? I'm waiting for the public beta to get released.

It works with 13.1 beta 1. I can start recording in the background. I hope that Apple will fix also iOS 12.4.x.
