[swift-evolution] [Draft] SwiftPM: Adding development package as a dependency

[Max Howell]

I’m wondering if the dev package should be inside Packages in some manner, perhaps as a symlink.

Otherwise when you looks inside Packages you don't see all your dependencies.

Also since this is related to the lockfile work, I’d like to wait until that is done, probably we could use very similar command line UX.

If you don’t mind?

I’ll revise the lockfile proposal today and get it moving.

Thanks for all your great work 👍🏻
