If I recall correctly you have to make a separate module with the bridging headers, but the first problem is that I can't remember exactly of the syntax of that file.

The second is that it's a lot of code and files to make when we only have one import to hack something quickly. For a full library it's probably a very cool feature though.

The third one is more related to my use case. I made a binding with a non-C codebase, and Swift cannot directly import C functions AFAIK, so I had to write C code in addition to the Swift one to make headers. It's not impossible, but it does take time to write all of that in a third programming language.

The fourth problem is related to library imports. In SPM, you either import a system library, or an xcframework. If your app targets any non-Apple platform, xcframeworks are not an option, so if you made a binding to your own lib that's annoying as it is probably not installed while you're building. And even if you're targeting Apple platforms, making an xcframework without Xcode is not well documented.

I probably missed a few problems as my experience is not very extensive, and there are probably better ways to achieve some of the things I wanted to do, but there isn't much documentation about all of that online anyway as far as I saw.

Alright yeah, I can concur with the packaging of the library so that it would eventually link and be accepted by the App Store which is surprisingly not the same set of requirements. It's just that I didn't completely chalked this up to Swift interop with C specifically but more the fact that multiple things Apple side need some jumping-through-hoops and that's just one of them.

I solved that through importing the dependency with Conan, and having extra steps running afterwards that would perform some quick and dirty lipo, xcodebuild and PlistBuddy stuff. It just wasn't that complicated, and only a few headscratches, but then it'd work and there was no need to touch that again, but situations may vary and I get that it could be painful in some cases.
