Answer 1

如果不确切地知道错误是什么，通常可以通过执行以下步骤找出修复编译/链接器错误的方法：

在错误视图中单击（或双击）错误（取决于IDE），这会将您带到错误适用的代码中的适用区域。
如果步骤1没有带您到任何地方（可能是链接器错误）或者您不确定该行为何产生错误，请尝试使用Google搜索确切的错误消息，并查看结果以查看它们是否有帮助。
如果所有其他方法都失败了，您可以来SO并发布描述错误所需的MINIMUM。发布您的整个构建日志并不是社区真正接受的

Answer 2

看起来您尚未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）。
打开右窗格并选择最左侧的标签。
选择源文件所属的目标。
