I am trying to make a simple camera app. But when I execute the code with iOS simulator, the iphoe show only black image and appear anything. I made it with the code below and two permissions which are Privacy - Camera Usage Description and Privacy - Photo Library Additions Usage Description. I need some help for solving this. import UIKit class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {   @IBOutlet weak var imageView: UIImageView!   @IBAction func launchCamera(_ sender: UIBarButtonItem) {     let camera = UIImagePickerController.SourceType.camera     if UIImagePickerController.isSourceTypeAvailable(camera){       let picker = UIImagePickerController()       picker.sourceType = camera       picker.delegate = self       self.present(picker, animated: true)     }   }       func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {           let image = info[UIImagePickerController.InfoKey.originalImage] as! UIImage     self.imageView.image = image     UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil)     self.dismiss(animated: true)   }       override func viewDidLoad() {     super.viewDidLoad()     // Do any additional setup after loading the view.   }
