Using async/await in Swift allows us to write asynchronous code that is easy to read and understand, but by itself it doesn’t enable us to run anything concurrently – even w...

Previously I talked about the concept of thread explosion, which is when you create many more threads than CPU cores and the system struggles to manage them effectively. Howev...

Swift’s Task struct has a static sleep() method that will cause the current task to be suspended for a set period of time. You need to call Task.sleep()&n...

Each task in a Swift task group must return the same type of data as all the other tasks in the group, which is often problematic – what if you need one task group to handle ...

Swift has a special task group type called a discarding task group, which has a very specialized function: tasks that complete are automatically discarded and destroyed, ...

If you’re writing a command-line tool with Swift, you can use async code in two ways: if you're using main.swift you can immediately make and use async functions as norm...

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...

Swift’s async let, Task, and task groups all solve a similar problem: they allow us to create concurrency in our code so the system is able to run them efficiently. Beyo...
