Answer 1

您可以执行@Ramy 的建议，也可以简单地从目标构建设置中删除Prefix Header。只需删除该字段的内容，您无法删除实际字段。

Answer 2

您的目标似乎是空的，并且您错误地删除了前缀文件。

选择您的项目目标（左侧组层次结构顶部的天蓝色图标），选择“目标”下的目标（等于项目名称），然后选择构建阶段标签并将文件添加到编译源码。

至于前缀文件，您可能需要重新创建它，它的名称为“YourProjectName-Prefix.pch”。这是我的前缀文件的内容：

#ifdef __OBJC__
    #import <Cocoa/Cocoa.h>
#endif

尝试一下，并考虑到如果出现问题并且您没有时间修复它，您可能总是想从头开始构建一个项目。

Answer 3

我收到这个错误是因为我不小心给了一个源文件一个 -m 标志而不是一个 -w 标志。这是胖手指。
