Use locally defined Package.swift

[markst]

This change makes it possible to work in a swift package independently which makes development much easier with Swift native code.

Rather than copying contents and generating Package.swift we can open our package in Xcode.app and manage dependencies.

Will supply more info.

Thanks for the heads-up! I'm really curious for the additional info teased. It sounds really promising!

I think that getting rid of Package.swift generation completely is not the right choice.
It would be better to give user ability to override Package.swift.
Also, this change alone brings new possible corner cases.
What if user will use external dependencies inside his Package.swift?
We then should be able to link them accordingly during the cinterop phase.
@ttypic what do you think?

@IlyaGulya thought I'd share this which defines a Package.swift at the root of a repo in order to allow development: https://github.com/markst/radioplayer-kt
