Xcode10.3, Swift5.1ならば下記のように書けるはずです。

swift
1        if let pickedImage = info[.editedImage] as? UIImage{
2            let imagedata = UIImage.jpegData(pickedImage)
3            UserDefaults.standard.set(imagedata, forKey: "pickedImage")
4            //UserDefaults.standard.synchronize() // 必要ありません
5            
6            icon2.image = pickedImage
7            picker.dismiss(animated: true, completion: nil)
8        }
