Malin Sundberg joins John to talk about her experiences of using SwiftUI to build and ship the time-tracking and invoicing app Orbit on most of Apple’s platforms, and what sort of things that can be good to keep in mind when using SwiftUI in a cross-platform context. Tower: Take advantage of Git’s powerful feature set […]
One really powerful aspect of SwiftUI’s overall API is that it enables us to draw things like shapes, gradients, and colors the same way that we render views and UI controls. For example, if we wanted to render a button shaped as a rounded rectangle, then we could do so by assigning a RoundedRectangle shape […]
When building iOS and Mac apps, it’s very common to want to present certain views either modally, or by pushing them onto the current navigation stack. For example, here we’re presenting a MessageDetailView as a modal, using SwiftUI’s built-in sheet modifier in combination with a local @State property that keeps track of whether the detail […]
At WWDC21, Apple introduced a new SwiftUI API that enables us to attach refresh actions to any view, which in turn now gives us native support for the very popular pull-to-refresh mechanism. Let’s take a look at how this new API works, and how it also enables us to build completely custom refreshing logic as […]
Recently, I’ve been more and more curious about web experience through mobile apps. Most of web browser apps look alike, I was wondering how could I recreate one with WebKit and SwiftUI. Let’s dive in. First Web View If you’re familiar with UIKit, since Apple deprecated UIWebView, there is only one way to support a […]
To move an existing iOS app codebase to SwiftUI can quickly become a challenge if we don’t scope the difficulties ahead. After covering the navigation and design layer last week, it’s time to dive deeper into the logic and handle the code migration for a database and the user preferences. If you’ve missed it, have […]
If SwiftUI is great for many things, migrating completely an existing app codebase to it can be really tricky. In a series of blog posts, I’ll share how to migrate an iOS app written in Swift with UIKit to SwiftUI. Today, let’s start with the navigation and the UI components with storyboards. Almost two years […]
Did you ever have to share your screen and camera together? I recently did and it was that easy. How hard could it be to create our own? Today, we’ll code our own webcam utility app for macOS in SwiftUI. I recently got chance to be part of my first online tech conference where I […]
Displaying dates or times is a very common requirement for many apps, often using a specific date formatter. Let’s see what SwiftUI brings to the table to make it easier for developers. Coming from UIKit, if I want to display a date, my code would look like something like this. import Foundation import UIKit let […]
I have put together a short video about creating particle effects with SwiftUI. It showcases the easiest/lazy way, which is great for simple eye candies and experimenting. Please note, that it is not the most performant way how to deal with particle effects in SwiftUI. If you need to go crazy about blending and high […]
