We'd also like to thank the RxSwift: Reactive Programming with Swift authors, whose work served as the basis for parts of this book:

• Scott Gardner has been developing iOS apps since 2010, Swift since the day it was announced, and RxSwift since before version 1. He's authored several video courses, tutorials, and articles on iOS app development, presented at numerous conferences, meetups, and online events, and this is his second book. Say hello to Scott on Twitter at @scotteg.

• Junior Bontognali has been developing on iOS since the first iPhone and joined the RxSwift team in the early development stage. Based in Switzerland, when he's not eating cheese or chocolate, he's doing some cool stuff in the mobile space, without denying to work on other technologies. Other than that he organizes tech events, speaks and blogs. Say hello to Junior on Twitter at @bontoJR.

• Florent Pillet has been developing for mobile platforms since the last century and moved to iOS on day 1. He adopted reactive programming before Swift was announced and has been using RxSwift in production since 2015. A freelance developer, Florent also uses Rx on Android and likes working on tools for developers like the popular NSLogger when he's not contracting for clients worldwide. Say hello to Florent on Twitter at @fpillet.
