フロントカメラに問題があり、何らかの理由で画像が反転します。私はこの問題を避けるためにimageView.transform = CGAffineTransform(scaleX: -1, y: 1)を使用しようとしました。しかし、私は裏カメラも裏返していることに気付きました。どんな解決策ですか？Swift 3 un-flipフロントカメラ画像
ImagePreviewViewController：

let cameraViewController = storyboard?.instantiateViewController(withIdentifier: "CameraViewController") as! CameraViewController
navigationController?.pushViewController(cameraViewController, animated: true)

var capturedImage : UIImage?
@IBOutlet weak var imageView: UIImageView!
override func viewDidLoad() {

imageView.image = capturedImage
close.setImage(UIImage(named: "Close.png"), for: UIControlState.normal)
//imageView.transform = CGAffineTransform(scaleX: -1, y: 1)
}

どのようにあなたが 'imageView'の内容を設定していますか？ –
