Когда я представляю modalViewController, и выбор всплывает справа, но я не могу выбрать картинку! Когда я касаюсь списка изображений, список может прокручиваться только вверх и вниз, но не может выбрать!

И вот мой код ViewController

Я понятия не имею, почему это может происходить.
Вот экран, на котором меня останавливают

Пожалуйста, ознакомьтесь с комментариями в следующей реализации.

 func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey: Any]) {

    // Do not dismiss this immediately, defer the dismissal
    // Dismiss this when execution returns from current function scope
    // This can be one of the following two 
    // a) early return from one of the `guard else` blocks OR 
    // b) after completing successfully in the end
    defer { picker.dismiss(animated: true) }
    
    guard let image = info[.editedImage] as? UIImage else {
        // Check if this is being printed
        print("Could not find edited image")
        return
    }
        
    guard let imageData = image.pngData() else {
        // Check if this is being printed
        print("Could not create pngData for image")
        return
    }
        
    // Rest of the implementation remains unchanged
}
