ios - IOS：：0：错误：未知参数：'-enable-batch-mode' 命令 CompileSwiftSources 失败，退出代码为非零

问题描述

我有一条我不明白的错误消息。我在www.swift.org上下载了 swift 工具链 4.0.3，因为我收到一条错误消息“Swift 4.2 编译器无法导入使用 Swift 4.0.3 编译的模块：”

现在，它给了我一个不同的信息：

可能是我必须删除那些论点，但我不知道在哪里搜索......

你有什么想法？

解决方案

TLDR

您无法解决此问题。使用 Xcode 9 或将您的代码库更新到 Swift 5。

完整答案：

在使用带有 Swift 4.0.3 工具链的 Xcode 10 来构建带有静态库的项目时，我遇到了同样的错误。

这里的问题如下：因为 Xcode 10 在 Swift 4.2 上运行，它为这个特定的 Swift 版本编写了一个编译命令。具体来说，它添加了-enable-batch-mode优化构建过程的标志。如果您手动删除标志（例如将整个命令粘贴到终端应用程序），它应该会成功。

当您更改工具链时，Xcode 本身还不够聪明，无法理解，4.0.3 中没有这样的东西-enable-batch-mode。

现在，您可以禁用批处理模式，它应该可以解决问题，对吧？您可以在Build Settings中添加新的 User-Defined SettingSWIFT_ENABLE_BATCH_MODE和 value NO。

但是猜猜，会发生什么？另一个未知的旗帜。
