错误：#import <Foundation/Foundation.h> 上的“Objective-C 方法的预期选择器”和“预期方法主体”答案

【问题标题】：Errors: "Expected selector for Objective-C method" and "Expected method body" on #import <Foundation/Foundation.h>错误：#import <Foundation/Foundation.h> 上的“Objective-C 方法的预期选择器”和“预期方法主体”

【问题描述】：

尝试在模拟器上运行项目时出现以下两个错误：

Objective-C 方法的预期选择器
预期的方法体

在 AppDelegate.h 文件中的 #import <Foundation/Foundation.h> 上

我尝试清理项目，关闭并打开 Xcode，重新启动 PC，尝试找到 type-o，但我找不到，我必须补充一点，我没有对应用程序委托文件进行任何更改，当我从在我的设备上测试更改为在模拟器上测试时，一切都发生了。

这是我没有修改的确切代码：

【问题讨论】：

编译时可能会出现此错误。在哪一行？
@AminNegm-Awad 正如我在标题中提到的那样，我在#import <Foundation/Foundation.h> 行上收到错误
在导入文件本身？
上面的代码是我的 AppDelegate.h 中包含的代码，我在#import <Foundation/Foundation.h> 行上得到了双重错误
能否请您提供您的前缀文件的内容？

【解决方案1】：

我在我的代码中发现了同样的错误。检查每个文件。其他文件顶部有额外的 + 号。删除它，它工作正常。检查任何文件上是否有任何多余的字符。
