ios - 在 swift 项目中找不到架构 x86_64 的符号

Question

我将java转换为objective-c，并通过bridging-header文件将其导入到swift项目中。当我构建 swift 项目时，出现以下错误：

Undefined symbols for architecture x86_64:
 "_OBJC_CLASS_$_DTPeople", referenced from:
  type metadata accessor for __ObjC.DTPeople in ViewController.o
ld: symbol(s) not found for architecture x86_64
  clang: error: linker command failed with exit code 1 (use -v to see     invocation)

我为 libjre_emul.a 设置了正确的目录
