在不真正知道您的错误是什么的情况下，通常可以通过执行以下步骤来弄清楚如何修复编译/链接器错误：

  1. 单击（或双击）错误视图中的错误（取决于 IDE），这应该会将您带到代码中错误适用的适用区域。
  2. 如果步骤 1 没有带您到任何地方（可能是链接器错误）或者您不确定该行产生错误的原因，请尝试使用谷歌搜索确切的错误消息，并查看结果以查看它们是否有帮助。
  3. 如果所有其他方法都失败了，您可以继续并发布描述您的错误所需的 MINIMUM。在这里发布您的整个构建日志并没有真正被社区接受

看起来您还没有将源文件分配给任何 Xcode 目标。

要解决：

  • 突出显示项目资源管理器中的每个源文件（左窗格）。
  • 打开右侧窗格并选择最左侧的选项卡。
  • 选择源文件所属的目标。
