ios - 错误 : "Expected selector for Objective-C method" and "Expected method body" on #import <Foundation/Foundation. h>

Question

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

预期方法体

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

我尝试清理项目，关闭并打开 Xcode，重新启动 PC，试图找到一个 type-o，但我找不到，我必须补充一点，我没有对应用程序委托(delegate)文件进行任何更改，一切都发生了当我从在我的设备上进行测试更改为在模拟器上进行测试时。

这是我没有修改的确切代码:

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额外字符。
