Any properties and methods that belong to an actor are isolated to that actor, but you can make external functions isolated to an actor if you want. This allows the funct...

Although Swift functions are synchronous by default, we can make them asynchronous by adding one keyword: async. Inside asynchronous functions, we can call other asy...

Creating and using an actor in Swift takes two steps: create the type using actor rather than class or struct, then use await when accessing its ...

Fetching JSON from the network and using Codable to convert it into native Swift objects is probably the most common task for any Swift developer, usually followed by dis...

Swift’s tasks use cooperative cancellation, which means that although we can tell a task to stop work, the task itself is free to completely ignore that instruction and carry...

Every task can be created with a specific priority level, or it can inherit a priority from somewhere else. But in two specific circumstances, Swift will raise the priori...

@MainActor is a global actor that uses the main queue for executing its work. In practice, this means methods or types marked with @MainActor can (for the most part)...

Both Swift Testing and XCTest allow us to test asynchronous code built with Swift concurrency by marking tests as async. This means we can wait for concurrent code to complete...

If you want to read the return value from a Task directly, you should read its value using await, or use try await if it has a throwing operation...

Swift’s actors are conceptually like classes that are safe to use in concurrent environments. This safety is made possible because Swift automatically ensures no two pieces of cod...
