This is basically libogg, wrapped for Swift Package Manager, for your convenience.

The libogg C source code is referenced as a submodule of this repository, so that it will be somewhat easier to check out another version tag, branch or commit, which may be more relevant to use in the future.

Add this repository as a dependency in your Xcode project. import COgg whenever you need to reference libogg's functionality.

All platforms that support usage of Swift and it's package manager should be supported. File an issue, if that isn't the case for you.
