?? Async/Await in Swift: The Game Changer for iOS Developers!

?? Still stuck in callback hell? There’s a better way!

Remember the old days of completion handlers? Nesting callbacks inside callbacks made code messy and unreadable. ????

?? Swift Concurrency changes everything! With async/await, your code is cleaner, more readable, and easier to maintain. Let’s see the difference.

? The Old Way: Completion Handlers (?? Callback Hell)

Imagine you’re fetching user data, profile picture, and recent posts. Using completion handlers, the code looks like this:

? Problems with this approach:

• Hard to read when multiple async calls are nested
• Difficult to handle errors
• Not scalable

?? The Swift Concurrency Way: Async/Await

Now, let’s do the same thing using async/await:

? Much cleaner & easier to understand

? No need for completion handlers

? Works naturally like synchronous code!

?? Example: Fetching User Profile in a SwiftUI App

Most iOS apps load data from APIs. Let’s say we need to:

? Fetch user profile

? Fetch profile image

? Fetch recent posts

Instead of sequential execution, we can run all tasks concurrently:

?? Boom! Now, all three API calls run in parallel, cutting down the total load time!
