21. Conclusion

You’re finally here! Congratulations on completing this book, and we hope you enjoyed learning about Combine from the book as much as we’ve enjoyed making it.

In this book, you’ve learned about how Combine enables you to write apps in a declarative and expressive way while also making your app reactive to changes as they occur. This makes your app code much more versatile and easier to reason about, along with powerful compositional abilities between different pieces of logic and data.

You started off as a complete Combine beginner, and look at you now; oh, the things you’ve been through—operators, networking, debugging, error handling, schedulers, custom publishers, testing, and you’ve even worked with SwiftUI.

This is where we part ways, but we have full confidence in you! We hope you’ll continue experimenting with Combine and constantly enhancing your “Combine muscles.” As the saying goes—“practice makes perfect.”

And like anything new you learn—don’t forget to enjoy the ride.
