ios - 在我的 iOS 应用程序中，架构 x86_64 的 undefined symbol

Question

尝试让我的应用程序为 arm64 做好准备并更新我的所有 pod。我更新了所有 pod，但收到此错误，因此应用程序无法编译。

    Undefined symbols for architecture x86_64:

Answer 1

有几件事可以解决这个问题:

1. 检查 Your-Workspace/Build Settings 和 Pod/Build Settings 的以下项目:Architectures、Build Active Architecture Only、Valid Architectures。这三个都应该在两个工作区之间匹配。

2. 尝试清理 (CMD-Shift-K) 并清理构建文件夹 (CMD-Option-Shift-K)。
