I have a camera app that records videos. My issue is that the preview layer is not in the correct position of its parent uiview, which has autolayout constraints.

After reading existing solutions, I’ve set . videoGravity to .resizeAspectFill and the preview layer’s frame to the uiview .bounds from the uiviewcontroller viewDidLayoutSubviews function. Still running into the same issue and am unsure what to try at this point. Any guidance would be appreciated.

Here is my custom class for the preview view with autolayout constraints set via storyboard:

class CameraPreviewView: UIView {

override static var layerClass: AnyClass {
    return AVCaptureVideoPreviewLayer.self
}
    
var cameraPreviewLayer: AVCaptureVideoPreviewLayer {
    return layer as! AVCaptureVideoPreviewLayer
}
        
var session: AVCaptureSession? {
    get { return cameraPreviewLayer.session }
    set { cameraPreviewLayer.session = newValue }
}

override func layoutSubviews() {
    super.layoutSubviews()
    self.cameraPreviewLayer.frame = self.bounds
    self.cameraPreviewLayer.videoGravity = .resizeAspectFill
}    

func refreshLayout() {
      self.setNeedsLayout()
      self.layoutIfNeeded()
  }
}

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()
    
    DispatchQueue.main.async {
        self.cameraPreviewView.cameraPreviewLayer.frame = self.cameraPreviewView.bounds
        self.cameraPreviewView.layoutSubviews()
    }
    
    DispatchQueue.main.asyncAfter(deadline: .now() + 3.0) {
       self.runCameraSession()            
    }
}
