我是xcode的新手，我正在尝试使用xcode学习C语言。当我尝试运行它时，我得到了一个错误applemach-o链接器和链接命令失败，退出代码为1。我不明白关于栈溢出的其他关于移除pod或库路径的答案。请帮助并告诉我修复此错误的每一步。｛编辑｝很抱歉提供的信息很少。这是代码和错误

C语言命令行项目的XCode标准模板包含main.c，其中包含示例实现：
#include <stdio.h>
int main(int argc, const char * argv[]) {
// insert code here...
printf("Hello, World!n");
return 0;
}
您还没有向我们展示您的项目文件结构，但我认为您没有从项目中删除main.c。您的屏幕截图显示您创建的Example.c也包含main()函数定义。在C语言中，所有函数都在同一个平面全局级别上(没有命名空间和类(，因此linker(制作可执行文件的最后阶段(抱怨重复的_main符号。要解决这个问题，您应该：
- 将主函数中的测试代码从
Example.c移动到main.c。无论如何都要去掉Example.c - 将
Example.c中的函数重命名为main()之外的其他东西，并在main.c中的int main(int argc, const char * argv[])内部调用它
