Swift 项目:“缺少必需的模块"；导入模块化框架时

问题描述

设置

1. 我创建了一个包含 C 库 (CommonCrypto) 和一个 Objective C 文件的 swift 框架.

2. swift 项目中没有桥头.所以我创建了一个 module.modulemap 来将 CommonCrypto 和 Objective-C 文件导入到我的 swift 框架中.

   module.modulemap 内容:

这是 module.modulemap 示例链接:

所以，在我的 swift 框架中，一切正常.我可以像这样使用模数

问题展示

1. 归档模块化框架并作为构建产品导出.

2. 在我的 swift 示例项目中，将模块化框架添加到 Embedded Binaries

3. 当我在框架内使用某些东西时，此行出现错误

我已经尝试了很多解决方案，但仍然无法正常工作.

类似的问题:

1. 备注

   如果框架存档在同一个开发环境中，则无需将 module.modulemap 添加到示例项目中.

   Setup

   1. I create a swift framework which include C library (CommonCrypto) and a Objective C file.

   2. There is no bridge-header in swift project. So I create a module.modulemap to import CommonCrypto and Objective-C file into my swift framework.

      module.modulemap content:

   Here is the module.modulemap sample link:Importing CommonCrypto in a swift framework

   3. In project settings, adding modulus.modulusmap path to swift compile

      So, in my swift framework, everything works fine. I can use modulus like this

   Problem shows

   1. Archive the modular framework and export as a built products.

   2. In my swift sample project, add modular framework to Embedded Binaries

   3. Error occurs on this line when I use something inside the framework

   I have try so many solutions, but still not work.

   Similar problems:

   1. Swift app: "Missing required module" when importing framework that imports static library

   2. Adding RealmSwift as a subproject: Missing required modules: 'Realm.Private', 'Realm'

   Is anyone have a good solution for this? Thx!!

   解决方案

   Solution

   iOS framework exists as a folder, create a module.modulemap to find out library or header file.

   1. Setup module.modulemap path

      In project/target/Build Settings/Swift Compile - Search Path/Import Path = "${SRCROOT}"

   2. Add below to module.modulemap

   Remarks

   You don't have to add module.modulemap to the sample project if the framework is archived on the same development environment.
