Apple just announced some upcoming changes to its Observation framework that might look familiar to users of our SwiftNavigation library! We obviously think it’s a great addition, and are happy to see Apple provide the same solution as ours directly in the framework.

But that doesn't mean you can't get a little help writing your migrations!
