Swift Programming Tutorial: Quick Introduction to Concurrency
Quickly Grasp The Concept of Concurrency
Let’s quickly grasp Swift concurrency, but in a way that feels like we’re two geeks chatting over coffee — or maybe energy drinks, because coders. Ready?
This article is part of my Swift Programming Tutorial series.
Imagine your computer is a super-powerful wizard. Swift concurrency is like instructing this wizard how to juggle multiple spells (tasks) at the same time without causing a fiery explosion.
The Problem: The Overwhelmed Wizard
Back in the old days (and still sometimes today), when you told your wizard to do a spell (like downloading a file), they’d be like:
“Cool, I’ll stand here and chant until this file is done. Don’t ask me to do anything else, though. I’m busy.”
This is called blocking. And it’s the reason your program or app sometimes feels like it’s frozen — your wizard gets too focused on one task and ignores the rest of the world. Annoying, right?
Concurrency to the Rescue: Multitasking Wizardry
Concurrency teaches your wizard how to juggle tasks like a pro. Instead of staring at one spell, it can:
