I'm trying to create an "Extensible Enterprise SSO" extension as described in the Introducing Extensible Enterprise SSO tech talk.
My SSO extension works fine, but I want to be able to access the camera (via AVFoundation) from within the SSO extension.
According to this thread (which I can't seem to be able to reply to) - it should be possible to access the camera from within an SSO extension, however this doesn't work for me.
When I try to access the camera, I get the permission dialog, but after accepting, the camera preview is empty and no camera frames are produced.
I don't get any errors/warnings in the logs, but it immediately fires AVCaptureSession.wasInterruptedNotification notification with AVCaptureSessionInterruptionReasonKey = 1 which corresponds to videoDeviceNotAvailableInBackground.
However, the SSO extension view controller is clearly not in the background, so is this a bug - or are there special rules for requesting camera permission in an SSO extension? The same camera access works fine in the host app, just not inside the extension.
Interestingly, accessing the camera in a WKWebView using various webcam test pages, doesn't work either.
All of these tests have been on iPadOS 18.
