Question

我在不带cocoapods的情况下将Google Firebase MLKit包含到了我的项目中。尝试构建时，出现Undefined symbol错误：Xcode error image

Undefined symbols for architecture armv7:

      l45918 in TextDetector

ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

到目前为止，我已经尝试过：

退出Xcode，然后清理构建
手动以及框架的拖放
链接了所有必需的资源文件夹
删除Xcode临时文件
将symbols hidden by default下的Build Settings设置为No 尽管框架TextDetector已链接到正确的目标。

所有这些似乎都不起作用。我遵循Integrate without CocoaPods进行框架设置。

Project Structure Image和Architecture in Build Settings

此问题已解决。我在上述Firebase链接中添加了.zip文件随附的所有其他框架。 List of Frameworks。这不是简单的设置，在readme和网站中都没有提及。可能不需要所有这些框架，但是许多框架是相互依赖的，因为它们在每个框架的module.modulemap中已指定。
