Create a professional looking app from start to finish that takes advantage of iCloud technology. Rather than working with Storyboarding for building your UI, you'll use code to build professional looking screens. Using code is standard for professional developers to fit form factor alignment across multiple screen sizes and other design constraints.First, you'll build a basic, functional UX screen. Then you'll incorporate iCloud with CloudKit for data persistence and private, public, and shared databases. Here your code-drive UI design will expand out to developing professional looking screens with animation. You'll also learn to work with reminder and notification boxes, sharing data between your users, and adding functionally for interaction with other Apps. Finally, you'll tackle testing and using Test Flight before publishing your app to the App Store. This book offers a practical guide for coders at any level who want to learn and create professional looking iOS apps leveraging the database features of iCloud and the numerous extensions that Apple provides in the Xcode environment. Create professional looking apps that are secure and your users will love! What You'll LearnLeverage CloudKit for Backend as a ServiceHandle Asynchronous processesShare data among users of your app with simultaneous modificationsWho This Book Is ForiOS developers familiar with the basics of Swift coding who want to work with iCloud databases or move into more advanced fields, such as using extensions or designing UX in code.

Build solid software with modern and safe concurrency features. Concurrency is one of the hardest problems in computer science. For years, computer scientists and engineers have developed different strategies for dealing with concurrency. However, the original concurrency primitives are complicated and difficult to understand, and even harder to implement.Using the new async/await APIs in Swift, this book will explain how your code can abstract a lot of the complexity with a simpler interface so you never have to deal with concurrency primitives such as semaphores, locks, and threads yourself. This will allow you to write concurrent code that is easier to read, easier to write, and easier to maintain.  These new APIs are deeply ingrained into Swift, offering compile-level features that will keep you from writing dangerous concurrent code.You'll start by exploring why concurrency is hard to implement in a traditional system. Explaining the definition of concurrency and what its primitives are will help you understand why they are hard to use correctly. These concepts will become clearer as you work through the sample projects. The book's focus then shifts exclusively to the new APIs, helping you understand how the integration of the system with the language itself makes it easier for you to write concurrent code without overstepping the bounds of the concurrency safe zone.By the end of the book, you'll have a solid foundation for working safely with concurrent code using the new async/await APIs.What You'll LearnUnderstand concurrency and its traditional problems Work with the new async/await API and all its features, from the basic usage and await keywords, to task groups and async sequences.Implement modern and safe concurrent code that you can start using right awayWho This Book Is For  Experienced iOS developers at a semi-senior or senior level. Knowledge on the Grand Central Dispatch is a bonus, but not required.
