I am trying to add objective-c libraries to my Swift 3 project (Xcode 8 IDE). But objective c interface header is not getting generated automatically. I tried to add bridging header manually but showing linking error saying bridging header .h is not found. Any help would be appreciated :)

推荐答案

这里是问题的解决方案.

Here the solution for the issue.

• 创建一个新的头文件并将其命名为您的项目名称-Bridging-Header.h".文件必须保存到您的项目文件夹中
• 选择您的 xcode 项目 -> 选择您的构建目标 -> 选择构建设置 -> 单击顶部的全部"选项 -> 搜索 Swift Compiler - General
• 选择Objective-C Bridging Header 项目并双击其值字段(同一行的右侧).将出现一个弹出窗口，您可以在那里输入您的桥接头文件路径(按照以下步骤提供头文件路径).

• 打开 finder 并将您的桥接头文件拖放到弹出窗口中.现在它将为桥接头创建一个绝对路径.要制作相关路径，您可以将路径指定为 $(PROJECT_DIR)/$(PROJECT_NAME)/$(PROJECT_NAME)-Bridging-Header.h

• Create a new header file and name it like "your project name-Bridging-Header.h". The file must be saved to your project folder
• Select your xcode project -> select your build target -> select build settings -> click the "all" option at the top -> search for Swift Compiler - General
• Select Objective-C Bridging Header item and double click on its value field (right side of the same row). One popup would appear and there you can enter your bridging header file path (Follow the below steps to provide header file path).

• Open finder and drag and drop your bridging header file to the popup. Now it will create an absolute path for bridging header. To make relating path, you can give the path as $(PROJECT_DIR)/$(PROJECT_NAME)/$(PROJECT_NAME)-Bridging-Header.h

单击外部以保存该值.完毕！！现在您可以将您的 Objective-C 库(例如#import "SVProgressHUD.h")导入桥接文件并开始在您的 swift 项目中使用它.

Click outside for the value get saved. Done!! Now you can import your Objective-C libraries (eg. #import "SVProgressHUD.h") to bridging file and start using it in your swift project.
