我尝试使用AVKit打开摄像机，在创建CameraView和AVCaptureVideoPreviewLayer对象时出现以下错误：
Publishing changes from within view updates is not allowed, this will cause undefined behavior.
我知道可以通过添加DispatchQueue.main.async {}来解决这个问题，但我不知道确切地把它放在哪里。
我正在创建CameraView，如下所示：

CameraView(size: geometry.size)
                            .environmentObject(cameraViewModel)
                            .ignoresSafeArea()

在里面，它看起来像：

struct CameraView: UIViewRepresentable {
    @EnvironmentObject var cameraViewModel: CameraViewModel
    
    var size: CGSize
    
    func makeUIView(context: Context) -> UIView {
        let view = UIView()
        
        /* error occurs here */
        cameraViewModel.capturePreview = AVCaptureVideoPreviewLayer(session: cameraViewModel.captureSession)

        cameraViewModel.capturePreview.frame.size = size
        
        cameraViewModel.capturePreview.videoGravity = .resizeAspectFill
        
        view.layer.addSublayer(cameraViewModel.capturePreview)
        
        return view
    }
    
    func updateUIView(_ uiView: UIView, context: Context) {
        
    }
}

最后，CameraViewModel保存capturePreview，即：

@Published var capturePreview: AVCaptureVideoPreviewLayer!
