Hey @splons,

I hope to address this next week, as I am still working on patch 3.0.0 for PopupView.

Have a nice day, Tomasz

Thank you. This new API became available in iOS 17.2

Turns out there is a SwiftUI modifier called .onCameraCaptureEvent that can easily be added to capture the physical volume button presses and then trigger photo capture. I added this to my custom camera screen implementation.

So maybe this feature request is not necessary -- particularly if you are using SwiftUI.

.onCameraCaptureEvent { event in
	if event.phase == .ended {
		captureOutput()
	}
}

Here is an example of how to integrate the .onCameraCaptureEvent modifier into your MCamera set

struct CustomCameraScreen: MCameraScreen {
    @ObservedObject var cameraManager: CameraManager
    let namespace: Namespace.ID
    let closeMCameraAction: () -> ()
    
    var body: some View {
        if #available(iOS 18.0, *) {
            DefaultCameraScreen(
                cameraManager: cameraManager,
                namespace: namespace,
                closeMCameraAction: closeMCameraAction
            )
            // add camera screen modifiers here
            .onCameraCaptureEvent { event in
                if event.phase == .ended {
                    captureOutput()
                }
            }
        } else {
            DefaultCameraScreen(
                cameraManager: cameraManager,
                namespace: namespace,
                closeMCameraAction: closeMCameraAction
            )
            // add camera screen modifiers here
        }
    }
}

Using AVCaptureEventInteraction would still be helpful as it would allow MijickCamera to be used in Control Center, Action button, or Lock screen extensions as outlined in Creating a camera experience for the Lock Screen
