Dive into Combine! Writing asynchronous code can be challenging, with a variety of possible interfaces to represent, perform, and consume asynchronous work - delegates, notification center, KVO, closures, etc. Juggling all of these different mechanisms can be somewhat overwhelming. Does it have to be this hard? Not anymore! In this book, you'll learn about Combine - Apple's framework to work with asynchronous events in a unified and reactive way that ensures your app is always up to date based on the latest state of its data. Who This Book Is For This book is for intermediate iOS developers who already know the basics of iOS and Swift development but are interested in learning declarative/reactive programming and take their app and state management to the next level. You'll also find this book interesting if you're interested in SwiftUI - as many of the reactive capabilities keeping your SwiftUI views up-to-date are built on top of Combine. Topics Covered in Combine: Asynchronous Programming with Swift What & Why: Learn what is Combine and reactive programming and the problems they solve, and how you can unify all of your asynchronous piece of work. Operators: Learn how to compose, transform, filter and otherwise manipulate different pieces of asynchronous work using operators. In Practice: You'll gain knowledge on various topics and techniques you'll leverage when writing your own real-life apps, as well as practice these techniques with actual hands-on apps and projects. SwiftUI: You'll learn about how Combine is deeply rooted within SwiftUI and provides it with the ability to reactively update its views based on the state of your app. Advanced Combine: Once you've got a handle on the basics, you'll dive into advanced Combine topics such as Error Handling, Schedulers, and Custom Publishers. By the end of this book, you'll be a pro in building full-fledged applications using Combine's various abilities.

Learn Reactive Programming in Swift with RxSwift!The popularity of reactive programming continues to grow on an every-increasing number of platforms and languages. Rx lets developers easily and quickly build apps with code that can be understood by other Rx developers - even over different platforms.Not only will you learn how to use the RxSwift port to create complex reactive applications on iOS, you'll also see how to easily solve common application design issues by using RxSwift. Finally you'll discover how to exercise full control over the library and leverage the full power of reactive programming in your apps.This books is for iOS developers who already feel comfortable with iOS and Swift, and want to dive deep into development with RxSwift.Topics Covered in RxSwift:- Getting Started: Get an introduction to the reactive programming paradigm, learn the terminology involved and see how to begin using RxSwift in your projects.- Event Management: Learn how to handle asynchronous event sequences via two key concepts in Rx - Observables and Observers.- Being Selective: See how to work with various events using concepts such as filtering, transforming, combining, and time operators.- UI Development: RxSwift makes it easy to work with UI of your apps using RXCocoa, which provides integration of both UIKit and Cocoa.- Intermediate Topics: Level up your RxSwift knowledge with chapters on reactive networking, multi-threading, and error handling.And much, much more!By the end of this book, you'll have hands-on experience solving common issues in a reactive paradigm - and you'l be well on your way to coming up with your own Rx patterns and solutions!

★★If you want to know more about Wicca than keep reading★★ Witchcraft, Wicca, Magick and Green Witches sound like a combination of everything dark and mysterious at least that is often the way witchcraft and Wiccans viewed. This book will change the way you think about these taboo topics. The many misconceptions that revolve around witchcraft can be dated back hundreds of years. It was considered a practice that lured those down a path of evil and sin. These misconceptions are laughable once you begin to research into the practice or religion that incorporates witchcraft into their belief systems. Green witches and Wiccans are not anything like the images that often flood your mind when you think of spellwork and magic. While some may say witchcraft is only for those wishing to cast ill-intent on to those who have worn them. This book will show you that witchcraft isn't about just about spells to get what you want. While the Wiccans and witches alike can manifest significant changes in their life, there is more to the belief system than that. Wicca is a spiritual path that can help you to understand and ignite the passion you have hidden inside. Wicca for Beginners will reveal to you how you can tap into the energy sources that surround you. You will also learn the various elements that make up the core Wicca philosophies, such as: What witchcraft is (it's nothing like they depict in movies) What the Wicca religion is all about. The steps to becoming Wiccan The major holidays of the Wiccan religion How magic and spell work play a role in Wicca practices. If you have been searching for a spiritual path, you might find it through gaining a better understanding of what Wicca is. This religion is one that focuses on the energies of the earth and natural elements. It is one that promotes making a connection to the spiritual world as you learn to make a deeper connection with yourself. If you have ever been curious about witchcraft, green witches, or Wicca, then Wicca for Beginners will provide you with the truth of what each of these entails. You might realize that deep down that this is the path for you, and you will learn the steps you can take to continue on this path once you have finished reading this book.

Developing apps for Apple’s broadening platform of devices is an exciting topic these days. Apple created the Swift programming language to build state-of-the-art apps using the latest Apple technologies. In this 200-page book, author Scott Gardner articulates the similarities and differences between traditional Objective-C based programming and Swift, revealing what you need to know from syntax changes to emerging best practices and paradigm shifts, to write powerful, expressive, and flexible code in Swift. Written at a brisk pace and in a methodical style, you'll learn how to apply your Objective-C skills to successfully transition to programming in Swift. In this book, you'll learn: • What is Swift and how does it compare to Objective-C • How to become proficient in Swift by leveraging your existing Objective-C skills • How to take advantage of new capabilities in Swift • What are the emerging best practices in Swift programming Transitioning to Swift reaches out to all developers who are interested in creating state-of-the-art apps for Apple’s broadening platform of devices for both consumers and enterprise. Apple's introduction of the new Swift programming language raises many questions. This book addresses those questions directly, and prepares developers for building the next generation of apps in Swift to surprise and delight users the world over.
