ld：未找到架构 x86_64 的符号 clang：错误：链接器命令失败，退出代码为 1（使用 -v 查看调用）

我已经尝试了一切以使其再次工作，并且我从面临类似问题的其他帖子中读取的堆栈溢出的所有内容

-重新安装 pod -更新吊舱 -新的podifile - 移除目标 - 删除派生数据 -清洁项目 - 重启模拟器 -重启Xcode

我什至不知道我做了什么改变才能出现这个问题，以前从来没有遇到过这个问题

感谢任何帮助！

【解决方案1】：

没有示例项目，我们只能猜测您做错了什么。

所以我猜... 如果您更新到 Xcode 12 - 转到项目设置，滚动到底部的 User-Defined 部分并删除 VALID_ARCHS 设置。如果你没有它 - 那么我的猜测是错误的，我祝你好运：D。

统一更新： 我找到了same answer

【讨论】：

我在我的项目中找不到 VALID_ARCHS

【解决方案2】：

这个错误是我不小心删除了我不知道的 pod 文件中的代码造成的。

删除 pod 并将其移回没有帮助

停止帮助是

pod deintegrate
pod install
