Swift SDK Lightweight

Hi guys, I just started integrate the SDK in a new swift project but I'm confused cause i literally have to copy almost everything from the repository to make my project works.
I cloned the sample repo, but I don't understand why do I have to take all the enums, extensions, typealias, etc... while they should be embedded in the SDK?

Don't you have a lightweight version of the sample? Or another version of the SDK that prevent us to do all the copy/past stuff?

Thanks
