I create an app with PHImagePicker support. It works and I could select multiple photos from photo library and import them into this app. But when I reopen this pickerController, the previous selected images are there with blue marks. I must to unselect them first to select some new images.

My question is how could I clear the previous selected images state each time I open the imagePickerController?

PHImagePicker

import UIKit
import PhotosUI

public protocol PHImagePickerDelegate: AnyObject {
    func didSelect(images: [UIImage]?)
}

class PHImagePicker: NSObject {
    
    private let pickerController: PHPickerViewController
    private weak var presentationController: UIViewController?
    private weak var delegate: PHImagePickerDelegate?
    private var images = [UIImage]()
    
    public init(presentationController: UIViewController, delegate: PHImagePickerDelegate) {
        var config = PHPickerConfiguration()
        config.selectionLimit = 3
        // only show images
        config.filter = PHPickerFilter.images
        
        self.pickerController = PHPickerViewController(configuration: config)
        
        super.init()
        
        self.presentationController = presentationController
        self.delegate = delegate
        self.pickerController.delegate = self
    }
    
    private func pickerController(_ controller: PHPickerViewController, didSelect images: [UIImage]?) {
        controller.dismiss(animated: true, completion: nil)
        
        self.delegate?.didSelect(images: images)
    }
    
    public func present(from sourceView: UIView) {
        self.presentationController?.present(pickerController, animated: true)
    }
}

extension PHImagePicker: PHPickerViewControllerDelegate {
    func picker(_ picker: PHPickerViewController, didFinishPicking results: [PHPickerResult]) {
        // clear images array
        self.images = []
        
        // dismiss the picker
        picker.dismiss(animated: true, completion: nil)
        print(picker)
        print(results)
        
        for result in results {
            print("
