As a platform, iOS offers numerous APIs to write asynchronous code and, many a times, this choice becomes hard to manage and a single code base ends up comprising multiple Asynchronous API usages, for example, closures for small Async tasks, delegation for background tasks, notification center for event-based tasks, and such. Managing and modifying such a code base might become a headache even if it is written in the best way possible, and the problem becomes more severe if a big team is involved with a single code base. RxSwift brings in uniformity so that different types of requirements (mentioned earlier) are handled with RxSwift code and hence you, as a developer, get more control over the processes and different module interactions within the app.
The main mission of this book is to give you a platform to catapult your skills to be on par with the best RxSwift developers out there. Follow the content in the book as per the schedule, and rest assured that you will achieve the mission.
