Apparently it's quite easy.

显然很容易。

1. You have to first make sure you're prepending your class declaration with @objc so that it's available to your Objective-C ones.
2. 您必须首先确保您使用@objc预挂类声明，以便您的Objective-C可以使用它。

For example:

例如:

import Foundation

// Belongs to target 'TestProject'
@objc class SwiftController: UIViewController {

    //... truncated

}

2. Now you simply have to import the name of your target (that the swift controller belongs to), appended with '-Swift.h'—exposing its interface—like so:

   现在，您只需导入目标的名称(swift控制器所属的名称)，并添加“-Swift”。h的暴露其类似于接口:

   #import "TestProject-Swift.h"

   #进口“TestProject-Swift.h”

#2

Create a new file "YourAppName-Bridging-Header.h" and in this file you have to import "Your objective-C view controller.h"

创建一个新的文件“YourAppName-Bridging-Header”。在这个文件中，你必须导入"你的objective-C视图控制器。h"

Go to Build setting and search for bridging header and link with your birdging-header path.

转到构建设置和搜索桥接头和链接您的birdgheader路径。

Now you are able to write code in swift as usual.

现在您可以像往常一样用swift编写代码了。
