ios - 从 xcode 9.2 升级到 xcode 9.4.1 后链接器命令失败

Question

我将 XCode 从 9.2 升级到 9.4.1，现在收到此错误:

ld: Assertion failed: (target->definition() != ld::Atom::definitionProxy), function addDyldInfo, file /Library/Caches/com.apple.xbs/Sources/ld64/ld64-351.8/src/ld/OutputFile.cpp, line 4213.

编辑:这是详细的错误消息。

这可能是由于命令行工具而发生的。尝试 Xcode -> 首选项 -> 位置并将命令行工具设置为 Xcode 9.3。
