我只是试图让我的第一个XCTestCase实现，一切都很好，但是当我执行测试用例时，我面临“构建失败”：
Undefined symbols for architecture x86_64:
"_OBJC_CLASS_$_Node", referenced from:
objc-class-ref in Test01.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
它当然是一个愚蠢的配置（编译/链接）错误，但我没有找到自己或现有帖子的解决方案： - （
提前感谢任何帮助。
祝你有个美好的一天。
