I created a XCFramework from a C Library (say a libc.a and corresponding “include” folder with header files) , lets call it C.xcframework. I want to interact with it from Swift, so I created a modulemap and corresponding header file, like this:
module.modulemap
/// Expose C for Swift usage
module C {
header "shim.h"
}
Shim.h
#ifndef shim_h
#define shim_h
// A shim header to bridge C to a Swift modulemap
#include <libc/header.h>
#endif /* shim_h */
As this is a C library, to offer a better interface to my Swift App, I wanted to wrap it in a Swift Framework, let’s call it S framework. This S framework imports C.xcframework within the “Embedded Frameworks” section. The wrapper can now do import C and have access to all the functions exported by the modulemap without any issues.
wrapper.swift
import Foundation
import C
// Wrapper code...
Now it is time for my App to make use of the S framework. To do so, I decided to create another S.xcframework. So I went ahead and archived the different architectures (iOS and iOS simulator). This time the compiler, as it is Swift code, created a Modules folder with the generated Modulemap for S and corresponding interface files. From this two archives I created a S.xcframework with the usual CLI command, referencing both architectures.
My App now imports S.xcframwork, and when I go and do the import S, I receive error:
No such module C.
ios-simulator.swiftinterface file on module S
import Foundation
import C // !Error here, No such module C
@_exported import S
import Swift
// header code...
Thanks in advance for your suggestions or help
