GoogleSignIn.framework添加失败，究其原因

Undefined symbols for architecture arm64: "OBJC_CLASS$_LAContext", referenced from: objc-class-ref in libSignet-SDK.a(SignetFingerUtil.o)ld: symbol(s) not found for architecture arm64clang: error: linker command failed with exit code 1 (use -v to see invocation)
弄了老半天，一直编译不成功，气死了都快最后在一个帖子上找到了答案，非常感谢大佬
xcode的link中添加苹果的framework库localAuthentication. framework即可解决
你说这不是坑人吗
