What are some new things you learn about #SwiftUI lately?

Over the course of making several SwiftUI apps, I've discovered quite a few hidden magic of SwiftUI that are quite fun.

Here are 6 interesting SwiftUI features in View Builder many don't know are even possible 🤯

🤯 View protocol with enum

Struct is not the only way to describe #SwiftUI views. Learn how you can achieve the same thing with just enum

🤯 Conform primitive type to View protocol

You can also conform any value type or primitive type to View protocol

The only requirement View needs is to yield a reasonable body.

Have you recently discovered some nifty UIKit APIs that you wish you had known earlier?

Apple introduces new changes every WWDC but it may take a while until they can be adopted in production, hence developers forgot.

Here are 9 useful APIs from iOS 7 - 15 many fail to notice

keyboardDismissMode, iOS 7

Have you tried making the keyboard dismissal follow along drag gesture? It's not an easy feast but I still see manual implementation in some codebases.

They didn't know that in iOS 7, you can specify keyboardDismissMode to be .interactive.

NSLayoutConstraint.active, iOS 8

I know everyone should be using NSLayoutAnchor and not the tedious NSLayoutConstraint.

Before iOS 8, we needed to find the view that is the closest common ancestor of the items managed by the constraint, and it is a very tricky task.

Swift is a very typesafe and expressive language.

With newer features mean we can find new ways to write even more concise Swift code.

Below are 5 sweet techniques that you can use to supercharge your codebase #iosdev 💪🤩

💪 allSatisfy

Instead of using filter and count, you can use allSatisfy to check whether all element satisfies a given condition

💪 keyPath

Available since Swift 5.2, keyPath is a type that references a property, allowing us to write much cleaner code.

Given that it is a type, we can store keyPath, pass it around, and combine them.
