hi Junipe.

Your demo and blogs on CaptureExtension have been super helpful for me developing my extension ❤️.
But, on this given issue, I didn't think the reason that the main App was terminated is that it doesn't start a capture session when launched. Actually it is because the AVCaptureEventInteraction was not added to the window.

With executing these
let view = await WidgetControlIntentDependency.shared.getAVCaptureEventInteractionHoldingView() if let vc = UIViewController.topMost, let view = view { vc.view.addSubview(view) view.frame = .init(origin: .zero, size: .zero) }
the main App would not be terminated by the system under any circumstances.

Best regards.

Thanks for sharing. I just tested on this PR by removing the viewModel.setupTemperaryCameraSession() line which setup a temporary camera session.

Since once the AVCaptureEventInteraction is setup, it will no longer be removed. But I find that the main app will still be terminated in the following steps:

1. Launch the main app, put it in the settings page.
2. Go to the home screen.
3. Press Camera Control to launch the app.
4. Stay in the settings page, and a few seconds later, it will be terminated.

Currently I am using iOS 18.3.1, but I think Apple still doesn't fix this issue yet.
