Introducing Swift Atomics Atomic operations are operations that run completely independently of other processes and will be fully executed without interruption. In this post on the official Swift blog, Karoy Lorentey from the Swift team announces Swift Atomics, a new open-source Swift package that enables low-level atomic Swift operations. #atomic #concurrency
Swift globals and static members are atomic and lazily computed A lazy stored property in Swift is a property whose initial value is not calculated until the first time it used. This is useful as it allows us to delay the initialization of a property that requires a computationally expensive setup until that property is actually needed. In this post, Jesse Squires reminds us that Swift globals and static members are also lazily initialized, and he explains how the concept of atomicity is distinct from the concept of thread-safety. #concurrency
Static Thread Safety This is an interesting Swift evolution draft proposal. In it, Guy Brooker proposes some small language changes which would allow the Swift compiler to spot basic concurrent programming errors. I like the syntax Guy proposes for specifying execution context. #evolution #concurrency
Atomic Properties in Swift Vadim Bulavin demonstrates how we can use locking APIs available in Apple frameworks to implement atomic properties in Swift. Vadim first describes the core concepts relating to concurrency and atomic properties, before providing code examples of Swift atomic properties. #concurrency #locking #atomic
Basics of parallel programming with Swift This is a great post from Jan Olbrich in which he covers the basics of concurrency and parallel programming in Swift. Jan starts by describing the difference between concurrency and parallelism, and then walks us through the various mechanisms available to us in Swift. #concurrency #parallelism
Concurrency in Swift: One approach This is a great detailed post by Chris Lattner in which he describes one approach to concurrency in Swift. Chris looks at the current state of concurrency in Swift, outlines his vision of where we want to get to, and then presents how we can get there using an async/await model. #concurrency
Understanding Operation and OperationQueue in Swift Dejan Agostini explains what Operations and OperationQueues are, and provides Swift examples of how we can use them. This is a good introductory article on implementing concurrency on iOS. #Concurrency #operationqueue #iOS
All about Concurrency in Swift - Part 1: The Present Umberto Raimondi with the first in a series of articles on concurrency in Swift. This is an excellently detailed look at what we have at our disposal, covering everything from locks and threads, to Grand Central Dispatch. #concurrency
