# Project-Swift进口”。h "文件不刷新

I have a project with Swift and Objective-C code. In my current project I have the problem that the #import "Project-Swift.h" file does not refresh if I add new Swift modules.

我有一个关于Swift和Objective-C代码的项目。在我目前的项目中，我遇到了#import项目- swift的问题。如果我添加新的Swift模块，文件不会刷新。

#import "Project-Swift.h" // does not refresh if I add .swift files

So in the Objective-C universe, the swift code is not available. the files exists, but does only contains default #defines etc. No project related stuff.

因此在Objective-C中，swift代码不可用。文件存在，但只包含默认的#define等。没有项目相关的东西。

Clear Cache, rebuild, delete Derived Data does not help.

清除缓存、重新构建、删除派生数据都没有帮助。

Solved it. Forgot @objc(<class>). It is mandatory.

解决它。忘了@objc( <课程> )。它是强制性的。

Just use @objc before Swift Class that you want to use in Object-C code then Build the project. For example:

在Swift类之前使用@objc，您希望在Object-C代码中使用，然后构建项目。例如:

 @objc class Person : NSObject
 {
  // Swfit code goes here.
 }

Now #import "Project-Swift.h" will be available in you project to use.

现在# Project-Swift进口”。h"将在你的项目中使用。

In my case it worked by building for the other target I had on my project:

在我的案例中，它通过为我的项目的另一个目标而建立:

Check you have prefixed your class with @objc
检查你的类以@objc为前缀
Choose the other scheme (target)
选择其他方案(目标)
Build || Run
构建| |运行
The bridging file updates
桥接文件更新
Change the scheme back to the target I was working on
把计划改回到我正在做的目标
