MultiCam does not work in SwiftUI

[Lyashenko-Alex]

Describe the bug

I have tested SwiftUI example. It works fine with single camera. When I try to use multicam for PIP mode, it shows black screen. If I add the below code, canvas is black. I cannot see nothing.

if #available(iOS 13.0, *) { let front = AVCaptureDevice.default(.builtInWideAngleCamera, for: .video, position: .front) rtmpStream.attachMultiCamera(front) }

Will you please help me to work multicam in SwiftUI?

To Reproduce

In the viewModel, in the registerForPublishEvent() function, add the below code.

if #available(iOS 13.0, *) { let front = AVCaptureDevice.default(.builtInWideAngleCamera, for: .video, position: .front) rtmpStream.attachMultiCamera(front) }

The view is black.

Expected behavior

It should show PIP view like iOS example with Storyboard.

It seems that being called in the following order is not working:

MTHKSwiftUIView#updateUIView() ViewModel#registerForPublishEvent()

It worked well when attaching 'attachMultiCam' or 'attachCamera' in ViewModel's #config().
