You are attempting to use the newer iOS 12 API which requires Xcode 10. If you are using Xcode 9.4 then you are using iOS 11 and you need to use the soon to be older API.
您正在尝试使用需要 Xcode 10 的较新的 iOS 12 API。如果您使用的是 Xcode 9.4，那么您使用的是 iOS 11，您需要使用即将到来的旧 API。
private func imagePickerController(_ picker: UIImagePickerController,
didFinishPickingMediaWithInfo info: [String : Any]) {
picker.dismiss(animated: true, completion: nil)
guard let image = info[UIImagePickerControllerOriginalImage] as? UIImage else {
return
}
}

首先，您需要删除private关键字。可能会添加它以消除警告。
