![]() ![]() We can combine all the conditionals and attempt to build the pairs all inlined into a single cascading ternary operator tree and simply return that as the Group content. See Understanding_SwiftUI_DSL/ConditionalContent.swift at GitHub SwiftUI DSL if statements struct ContentView: View ) The complementary repository contains every code that this article discusses, may just skip to it right away. palette variant to get complete control over the colors in the image. ultraLight)) Image(systemName: 'checkmark.circle'). 00:22 As part of a new Mac app were developing, were going to create a permissions view. You can set weights and sizes: Image(systemName: 'checkmark.circle'). If the dissected code seems foreign to you, I highly recommend read through the previous article Understanding SwiftUI DSL (1/2) TupleView to familiarize yourself with the process. font(.system(size: 144)) Download this as an Xcode project. 00:06 In this episode, well see how SwiftUI previews help us design and implement our UI while using real model data. In SwiftUI Image view provides a way to initialize it using UIKit’s UIImage. Ultimately in just a few days I was able to create a new onboarding app called hello based on Kandji’s Liftoff. This past week was WWDC ‘21 and I came away pretty inspired with Apple’s new features in Swift 5.5 and SwiftUI 3. The code examples below are intentionally opted-out from using Function builders, Opaque return types, and Implicit returns to give an opportunity to see the underlying types and structures. Categories: Open Source Swift SwiftUI Xcode SF Symbols. This article uses the same method to dissect/introspect SwiftUI DSL statements using reflection. ![]() Design your layout using the inspector, insert menu and modifiers. ![]() In the current reading, we take a look on how SwiftUI DSL encodes view type information when dealing with if, if/else, and switch conditional branching statements. Download the videos and assets to refer and learn offline without interuption. let image // your image let targetSize CGSize(width: 100, height: 100) let scaledImage image. In the previous article Understanding SwiftUI DSL (1/2) TupleView we dissected SwiftUI DSL to see how view builders compose view tuples from view hierarchies, how the view hierarchy information (including modifiers) gets engraved into the type annotation of the body. That’s it You now have an extension that will resize any UIImage to a target size without stretching or distorting the original image. This article series aims to give you a perspective through code examples by recreating SwiftUI hierarchy with “vanilla” Swift. SwiftUI DSL backgrounds were discussed in great lengths when the feature landed. ![]()
