.. How to solve that?

Solution:

Because you tried in main queue.You must  try async then it will be solved.

My function to be as like below.

    func openCamera() {

        let authStatus = AVCaptureDevice.authorizationStatus(for: AVMediaType.video)

        switch (authStatus){

        case .notDetermined:

            showAlert(msg:"Camera access denied", controller: self)

        case .restricted:

            showAlert(msg: "Camera access denied", controller: self)

        case .denied:

            showAlert(msg: "Camera access denied", controller: self)

        case .authorized:

            if getCameraAccess() == true{

                DispatchQueue.main.async() {

                    

                    if(UIImagePickerController .isSourceTypeAvailable(UIImagePickerController.SourceType.camera)) {

                        self.imagePickerController.sourceType = .camera

                        self.imagePickerController.delegate = self

                        self.imagePickerController.mediaTypes = [kUTTypeMovie as String, kUTTypeImage as String]

                        self.present(self.imagePickerController, animated: true, completion: nil)

                        

                    }

                }

            }

            else{

                showAlert(msg: "Camera access denied", controller: self)
