代码在 armv7 上运行良好，但针对 arm64 进行编译时会抛出此必须在需要之前从模块‘Darwin.POSIX.sys.xattr’导入‘setxattr’声明"错误.

code is working fine on armv7 but compile for arm64 throws this "Declaration of ‘setxattr’ must be imported from module ‘Darwin.POSIX.sys.xattr’ before it is required" error.

u_int8_t b = 1;
    setxattr([path fileSystemRepresentation],
             "com.apple.MobileBackup", &b, 1, 0, 0);
