ld:警告:找不到自动链接库“swiftObjectiveC”

Question

我正在从事一个用obj-c编写的遗留项目(iOS应用程序)。该项目与用obj-c编写的遗留静态库链接。

使用Swift编写的代码对库进行了扩展，生成时没有错误。

问题是在项目级别上，它生成了以下错误：

ld: warning: Could not find auto-linked library 'swiftObjectiveC'

• 如何解决这个问题？

更新：

我不使用Cocoapods

Answer 1

这里有一个对我有用的解决方案：

显然，对于纯objective项目，您需要将这个$(TOOLCHAIN_DIR)/usr/lib/swift/$(PLATFORM_NAME)添加到目标的库搜索路径中。当我把一个库写成目标-c中的一个项目时，这个方法对我起了作用。
