Dealing with SwiftUI recreating Views too often can be a challenge. I would have liked to have seen more details on how this guy setup his models.

In my experience, you definitely have to minimize work done in Views and maybe avoid `@Published` properties on your model in favor of more explicit calls to `objectWillChange.send()` to signal when you really are ready for the Views to be updated. SwiftUI does not seem to do a very good job of coalescing by default.
