如何手动创建 Swift 桥接头

How to create a Swift Bridging Header Manually

• 向 Xcode 添加一个新文件(文件 > 新建 > 文件)，然后选择源"和单击头文件".

• Add a new file to Xcode (File > New > File), then select "Source" and click "Header File".

将您的文件命名为YourProjectName-Bridging-Header.h".示例:在我的app Station，文件名为Station-Bridging-Header".

Name your file "YourProjectName-Bridging-Header.h". Example: In my app Station, the file is named "Station-Bridging-Header".

创建文件.

导航到您的项目构建设置并找到Swift Compiler– 代码生成"部分.您可能会发现输入Swift编译器"进入搜索框以缩小结果范围.注意:如果你没有Swift Compiler – Code Generation"部分，这个意味着您的项目中可能没有添加任何 Swift 类然而.添加 Swift 文件，然后重试.

Navigate to your project build settings and find the "Swift Compiler – Code Generation" section. You may find it faster to type in "Swift Compiler" into the search box to narrow down the results. Note: If you don’t have a "Swift Compiler – Code Generation" section, this means you probably don’t have any Swift classes added to your project yet. Add a Swift file, then try again.

在Objective-C Bridging Header"旁边，您需要添加头文件的名称/路径.如果您的文件位于项目的根文件夹只是将头文件的名称放在那里.例子:ProjectName/ProjectName-Bridging-Header.h" 或者干脆ProjectName-Bridging-Header.h".

Next to "Objective-C Bridging Header" you will need to add the name/path of your header file. If your file resides in your project’s root folder simply put the name of the header file there. Examples: "ProjectName/ProjectName-Bridging-Header.h" or simply "ProjectName-Bridging-Header.h".

打开您新创建的桥接头并导入您的使用#import 语句的Objective-C 类.列出的任何类可以从您的 swift 类访问此文件.

Open up your newly created bridging header and import your Objective-C classes using #import statements. Any class listed in this file will be able to be accessed from your swift classes.
