How to modify imagePickerController (source camera) not to dismiss after pressing "Use photo" until 4 photos are taken?

Question

I want to take 4 photos before UIImagePickerController is dismissed. How to modify it? I have following button action and delegate:

@IBAction func take4Photos(_ sender: Any) {
                if UIImagePickerController.isSourceTypeAvailable(.camera) {
                    let image = UIImagePickerController()
                    image.delegate = self
                    image.sourceType = .camera;
                    image.allowsEditing = false
                    self.present(image, animated: true, completion: nil)
                    
                }
            }


func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        if let image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage{
       
        imagePicked = image
       
        self.dismiss(animated: true, completion: nil)
        
    }

I will recommend you to use ImagePicker, which can be easily installed through cocoaPods and it can fulfill your requirement with just one line of Code.

let imagePickerController = ImagePickerController()
imagePickerController.imageLimit = 4

You can check ImagePicker library here

Here's how you can use ImagePicker library to pick multiple images.

Create a button in Storyboard and have its outlet in the ViewController.

@IBOutlet weak var chooseImage: UIButton!

If you want to see the selected images in VC after selection, make an array of UIImages like this

var imageViews:[UIImageView] = []

Then, in viewDidLoad, add target to chooseImage button

chooseImage.addTarget(self, action: #selector(buttonTouched(button:)), for: .touchUpInside)

And declare buttonTouched function outside the viewDidLoad like this

  @objc func buttonTouched(button: UIButton) {
  let config = Configuration()
  config.doneButtonTitle = "Done"
  config.noImagesTitle = "Sorry! There are no images here!"
  config.recordLocation = false 
  config.allowVideoSelection = false. //If you don't want video recording

  let imagePicker = ImagePickerController(configuration: config)
  imagePicker.delegate = self

  present(imagePicker, animated: true, completion: nil)
}

Then, in the end, inside the extension, conform to ImagePicker delegate functions like this.

extension OwnerAddListingFacilitiesViewController:ImagePickerDelegate {

 func cancelButtonDidPress(_ imagePicker: ImagePickerController) {
    
    imagePicker.dismiss(animated: true, completion: nil)
  }


 func wrapperDidPress(_ imagePicker: ImagePickerController, images: [UIImage]) { //Don't know what exactly this function does }

 func doneButtonDidPress(_ imagePicker: ImagePickerController, images: [UIImage]) {
    for Count in 0..<images.count {
        let imageView = UIImageView(image: images[Count])
        imageView.frame = CGRect(x: (0 * (110 * Count)), y: 0, width: 50, height: 50)
        imageViews.append(imageView)
    }
    
        imagePicker.dismiss(animated: true, completion: nil)
  }

 }

You'll be able to see small thumbnail like images after selecting them and pressing done.
