此过程似乎有效（对于单个应用程序目标）：

This procedure seems to work (for single app target):

1. 不要添加 import TestLibrary ，因为Swift和Objective-C代码都将驻留在同一个应用程序目标中


2. 创建Test-Bridging-Header.h进行测试并添加＃ importTestLibrary / TestLibrary.h


3. 设置构建设置 Objective-C Bridging Header：Test / Test-Bridging-Header.h for Test


4. 从TestLibrary拖动libTestLibrary.a（在P下）使用二进制文件（在构建阶段）进入测试的链接库


5. 添加 let test = TestLibrary（）例如在ViewController.swift里面 viewDidLoad

1. Do not add import TestLibrary, since both the Swift and Objective-C code will reside in the same app target
2. Create Test-Bridging-Header.h to Test and add #import "TestLibrary/TestLibrary.h"
3. Set build setting Objective-C Bridging Header: Test/Test-Bridging-Header.h for Test
4. Drag libTestLibrary.a from TestLibrary (under Products) into Test's Link Library With Binaries (under Build Phases)
5. Add let test = TestLibrary() e.g. inside viewDidLoadin ViewController.swift

Voila ......

Voila ...
