How do I use C APIs and import headers with module maps?

Using C APIs in Swift can enhance the functionality of your Swift projects by allowing access to lower-level system features or third-party libraries. To use C APIs, you typically need to create module maps to import your C headers correctly. Here's how to do it:

Creating a Module Map

Module maps are files that describe how headers are organized and the relationships between them. To create a module map for your C APIs, follow these steps:

1. Create a folder called `Modules` in your project directory.
2. Inside this folder, create a file called `module.modulemap`.
3. Define your C headers in the module map file. For example:


    module MyCLibrary {
        umbrella header "MyCLibrary.h"
        export *
        module * { export * }
    }

Importing the Module in Swift

After defining your module map, you can import your C APIs into your Swift files as follows:


    import MyCLibrary

    func useCLibraryFunction() {
        myCFunction() // Call a C function declared in MyCLibrary.h
    }

Make sure to configure your project settings to recognize the module map location under 'Swift Compiler - Search Paths' and add the path to the 'Import Paths'.
