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

Question

尝试在模拟器上运行项目时出现以下两个错误：

1. Objective-C方法的预期选择器
2. 预期方法主体

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，但找不到任何东西，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，一切都发生了当我从在设备上进行测试变为在模拟器上进行测试时。

这是我没有修改的确切代码：

我在代码中发现了相同的错误。 检查每个文件。 在其他文件的顶部有多余的+号。 删除它，它工作正常。 检查任何文件上是否有多余的字符。
