Hero animations in SwiftUI

Animation is one of the powerful features of SwiftUI. I was shocked when I saw how easy we could animate changes in view hierarchy by simply mutating @State properties and attaching animation modifiers. This week we will talk about another animation type called hero animation. We will learn how we can implement hero animations using the new matchedGeometryEffect view modifier.

Styling custom SwiftUI views using environment

One of my favorite features of SwiftUI is styling. I love the idea of style protocols provided by every view and sharing them using the environment. I have already covered most of the style protocols for SwiftUI provided views in my previous posts. But what about custom views? This week we will learn how to share styling using environment for our custom views.

Focus management in SwiftUI

WWDC 20 brings us tons of new SwiftUI APIs, which we can use to improve our apps user experience without using UIKit. One of these new APIs was the focus management API that we can use on iOS, macOS, tvOS, and watchOS. This week we will talk about SwiftUI functionality that allows us to manage the focus in our apps.

Commands in SwiftUI

This week we will talk about another new API that Apple released this year during WWDC 20. Replacing AppDelegate with the new SwiftUI App Lifecycle brings us tons of new APIs that we can use to replace old functionality with a brand new declarative API. One of those APIs is commands, which we will cover today.

Keyboard shortcuts in SwiftUI

This year Apple released the new App Lifecycle API for SwiftUI, which brings tons of new modifiers to replace AppDelegate callbacks. I have already covered most of them in previous posts. This week, we will discuss the new keyboardShortcut modifier, which allows us to assign a shortcut to any interacting view.

How to use GeometryReader without breaking SwiftUI layout

Usually, I try to avoid GeometryReader as much as I can. But sometimes, we need it to build our custom view. This week we will talk about GeometryReader. The view that allows us to read its geometry and layout child views manually.

The magic of redacted modifier in SwiftUI

Redacted modifier is the thing that will have a great impact on how iOS apps handle loading states. During WWDC20, Apple showed us the easy way of hiding the data from home-screen widgets using the redacted modifier. Today we will talk about using the redacted modifier to hide sensitive data and handle loading states.

Mastering GroupBox in SwiftUI

Styleable views is the thing I love in SwiftUI. You can separate your view logic and its style. You can easily apply different styles in different conditions whenever you need to change appearance depending on the platform or other environmental requirements. This week we will talk about GroupBox, another view container that SwiftUI provides, and allows us easily change its look and feel using a style protocol.

Transactions in SwiftUI

Animations play a vital role in SwiftUI. We saw a lot of examples of complex animations that we can easily implement in SwiftUI. The guidance for building fluid animations in SwiftUI has the only one step: mutate your state, and SwiftUI will automatically animate changes in your views. Today we will talk about transactions, which is a hidden gem of SwiftUI.

Mastering ScrollView in SwiftUI

We had the scroll view from the very first version of SwiftUI. It was quite limited. But this year changed everything when Apple released ScrollViewReader during WWDC 20. This week we will learn all about scroll views in SwiftUI. We will learn how to scroll to the particular position and read the current offset of scroll view content.
