SwiftUI: Double-Edged Sword I really like this short post from Mohsen Alijanpour. One of the many benefits of migrating to SwiftUI from the world of UIKit, which assumes we will build using the MVC pattern, is that SwiftUI is architecure-less. That is, SwiftUI doesn't assume what architectural pattern we will use when building. Here, Mohsen highlights this freedom, while also reminding us that such freedom comes at the cost of more responsibility. Posted on July 1, 2020 #swiftui #uikit #architecture
Using SceneStorage for State Restoration in SwiftUI Apps iOS 14 introduces a new SwiftUI property wrapper, SceneStorage. In this short post, Natalia Panferova shows us how we can use it to persist tab selection in a tab-based app. Posted on June 30, 2020 #ios14 #swiftui
The magic of Animatable values in SwiftUI SwiftUI provides view modifiers which allow us to animate changes to a view's state. In this post, Majid demonstrates how we can build complex animations using Swift's VectorArithmetic protocol. Posted on June 29, 2020 #swiftui #animation
Integrating SwiftUI & UI Kit In this talk from dotSwift 2020, Ishmael Shabazz discusses integrating SwiftUI and UIKit. Ishmael first looks at how we can use UIKit views in a SwiftUI hierarchy, and then switches sides to show us how to add SwiftUI views to a UIKit hierarchy. Posted on June 28, 2020 #swiftui #uikit
SwiftUI, UIViewRepresentable, and attributed text This is an interesting post from Benedikt Terhechte on the difficulty of handling rich text with SwiftUI 1.0. To support Markdown in his Hyperdeck app, Benedikt needed a SwiftUI type which supported rich text via attributed text. However, as there is no native SwiftUI 1.0 type which supports attributed text, Benedikt needed to look for other solutions. Posted on June 26, 2020 #swiftui #uikit
What's new in SwiftUI It's WWDC20, and all new SwiftUI features are here! In this post, Majid takes a peek at some of these new features. There are some really cool additions in this iteration of SwiftUI, and I particularly like the new way of defining an app's entry point using the new App and Scene protocols.

Building a silly WatchKit App Erica Sadun with a short post describing her efforts to build a simple WatchKit app using SwiftUI. The amount of code required to implement her app was small, about 40 lines, but Erica encountered some problems when trying to deploy her app to hardware for testing.

TikTok logo-ish effect in SwiftUI Taking a break from WWDC, this post from Pavel Zak shows us how to create an image with a blurred and blended effect, similar to the TikTok logo. Pavel uses a custom ViewModifier, creating an effect which can be reused on any SwiftUI view. Posted on June 24, 2020 #swiftui
What’s new in SwiftUI for iOS 14 It's a big week, with lots of awesome new things to learn and try out. SwiftUI was always going to see big improvements this year, and luckily we have people like Paul Hudson to help us keep up with all the changes. This evolving post from Paul summarises the SwiftUI changes as Paul works through them, and he includes code samples for all. Bookmark and check back in daily.

The power of @ViewBuilder in SwiftUI Swift function builders allow us to create APIs which provide a DSL-like syntax. ViewBuilder is one such function builder, and is used by SwiftUI to create views. In this post, Majid shows us how we can build our own reusable SwiftUI views, using ViewBuilder to separate our presentation logic and content. Posted on June 22, 2020 #swiftui
