Learn Modern Swift Concurrency! For years, writing powerful and safe concurrent apps with Swift could easily turn into a daunting task, full of race conditions and unexplained crashes hidden in a massive nesting of callback closures. In Swift 5.5, Apple introduced a new concurrency model featuring the async/await syntax, which lets you write asynchronous code that reads like synchronous code. But like any new feature, here be dragons! So how will you achieve the much-desired mastery of modern Swift concurrency? Modern Concurrency in Swift comes to the rescue, showcasing what you need to know about async/await, tasks, actors and everything in between! Who This Book Is For This book is for intermediate Swift developers who are familiar with writing asynchronous applications and who want to leverage the concurrency features Apple introduced in Swift 5.5 and its evolution throughout the years, to write safer and more predictable asynchronous apps. Topics Covered in Modern Concurrency in Swift Using async/await: Learn how to use the new async/await keywords to define and run asynchronous work. Actors: Find out how to use the actor model to easily protect shared mutable state in a synchronized container. Tasks: You'll dive deeper into the Task type, which powers all asynchronous tasks in Swift's modern concurrency model. Task Groups: Use a Task Group to group multiple tasks together and run them concurrently, while using a familiar Array-like syntax to iterate over the results. Custom Asynchronous Sequences: Leverage the power of async/await in your own asynchronous work, by learning how to create custom AsyncStreams. Testing Asynchronous Code: Asynchronous code can be a challenging beast to test. You'll learn everything you need to tackle this challenge. One thing you can count on: After reading this book, you'll be prepared to leverage Swift's new concurrency features in your app to write safe, performant and predictable asynchronous code.

Dive into Concurrency in iOS!Concurrency is the concept of multiple things, or pieces of work, running at the same time. With the addition of CPU cores in our devices, knowing how to properly utilize your customer's hardware to the maximum is absolutely a must. Unfortunately, proper concurrency in iOS apps is one of the lesser-known, lower-level topics, that every developer wants to (and should) understand properly, but is usually intimidated by.This is where Concurrency by Tutorials comes to the rescue! In this book, you'll learn everything there is to know about how to write performant and concurrent code for your iOS apps. Who This Book Is ForThis book is for intermediate iOS developers who already know the basics of iOS and Swift development but want to enrich their knowledge, learning more about how to efficiently perform tasks without affecting the performance of their app, and how to properly divide work to utilize hardware to the fullest extent.Topics Covered in Concurrency by TutorialsWhat & Why: Learn what is Concurrency and why would you even want to utilize it in your apps?Grand Central Dispatch: Learn about Apple's implementation of C's libdispatch, also known as GCD, it's one of the simplest ways to queue up tasks to be run in parallel.Operations & Operation Queues: When GCD doesn't quite cut it, you'll learn how to further customize and reuse your concurrent work using Operations and Operation Queues.Common Concurrency Problems: Learn about some of the problems you could face while developing concurrent applications, such as Race Conditions, Deadlocks, and more.Threads & Thread Sanitizer: Understand various threading-related concepts and how these connect to the knowledge you've accumulated throughout this book.

Over the past two decades, there has been a huge amount of innovation in both the principles and practice of operating systems Over the same period, the core ideas in a modern operating system - protection, concurrency, virtualization, resource allocation, and reliable storage - have become widely applied throughout computer science. Whether you get a job at Facebook, Google, Microsoft, or any other leading-edge technology company, it is impossible to build resilient, secure, and flexible computer systems without the ability to apply operating systems concepts in a variety of settings. This book examines the both the principles and practice of modern operating systems, taking important, high-level concepts all the way down to the level of working code. Because operating systems concepts are among the most difficult in computer science, this top to bottom approach is the only way to really understand and master this important material.
