Package Manager and Other Changes
Section 1
Package Manager Dependency Mirroring
Swift 4.2 added lots of improvements to how we create packages, but Swift 5 has improved it dramatically. We are now able to mirror a dependency, so that we can have it cached or replicated, just in case the original dependency is no longer available. We are also able to specify minimum platform version, and finally, we can have multiple targets with different settings.
