图像未显示在单元格上

Question

我正在尝试拾取图像并将其转换为字符串以保存到模型var picture = ""中。我可以选择图片，但它不会显示任何有关我的错误的建议。

更新：我通过这些更改找出了答案，但仍然在模型中使用了字符串。

var imagePath = ""
var profilePic: UIImage?
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

    if let referenceUrl = info[UIImagePickerControllerReferenceURL] as? URL, let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
        ALAssetsLibrary().asset(for: referenceUrl, resultBlock: { asset in
            let fileName = asset?.defaultRepresentation().filename()
            let userModel = User()
            userModel.picture = fileName!
            let filePath = "\(NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0])/\(String(describing: fileName))"
            self.imagePath = filePath
            let imageData : NSData = UIImagePNGRepresentation(pickedImage)! as NSData
            imageData.write(toFile: filePath, atomically: true)
        UserDefaults.standard.set(imageData, forKey: "profileImage")
        UserDefaults.standard.synchronize()
        self.profilePic = pickedImage
        self.tableView.reloadData()
        }, failureBlock: nil)
}
    dismiss(animated: true, completion: nil)
}
