UIImagePickerControllerでカメラをキャプチャする方法

Question

###前提・実現したいこと
カメラを起動し、撮影した写真を画面に表示させるアプリを作っています。
delegateで画像の取得する機能のところでエラーメッセージが発生し、ボルドできません。

###発生している問題・エラーメッセージ

Computed property must have an explicit type.
'let' declarations cannot be computed properties.
Variable with getter/setter cannot have an initial value

###該当のソースコード

import UIKit
class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    @IBOutlet var myImage: UIImageView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    @IBAction func takePhoto(_ sender: AnyObject) {
     
        if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.camera) {
            
            let imagePicker = UIImagePickerController()
       
            imagePicker.delegate = self
           
            imagePicker.sourceType = UIImagePickerControllerSourceType.camera
           
            imagePicker.allowsEditing = false
         
            self.present(imagePicker, animated:  true, completion:  nil)
            
        }
    }
    
    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String: Any]) {
        
        let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage { // ここでエラー発生
            myImage.contentMode = .scaleToFill
            myImage.image = pickedImage
        }

        
        picker.dismiss(animated: true, completion: nil)
    }
}

よろしくお願いします。

Optional Bindingをしようとしているのにifの記述が抜けていますよ。

if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage { // ここでエラー発生
    myImage.contentMode = .scaleToFill
    myImage.image = pickedImage
}
