Xcode 体系结构 x86_64 的未定义符号：

Question

我从另一个开发人员那里接管了一个 Xcode 项目，并试图让代码在我的本地计算机上运行。

我收到此错误：

Undefined symbols for architecture x86_64:

这是我来自 Xcode 的日志文件：

这是我在 Architecture 下的内容： Architectur

这是我按照 facebook SDK 入门指南导入的框架文件：框架

Answer 1

似乎您的项目在链接时缺少依赖性，因为在链接阶段缺少FBSDKLoginKit.framework 。

尝试通过Facebook指南（ iOS版Facebook SDK入门）重新检查您的配置。

Answer 2

你可以试试rm -rf ~/Library/Developer/Xcode/DerivedData/*
