Published on: September 24, 2025Starting with Xcode 26, there’s a new way to observe properties of your @Observable models. In the past, we had to use the withObservationTracking function to access properties and receive changes with willSet semantics. In Xcode 26 and Swift 6.2, we have access to an entirely new approach that will make observing our models outside of SwiftUI much simpler.In this post, we’ll take a look at how we can use Observations to observe model properties. We’ll also go over some of the possible pitfalls and caveats associated with Observations that you should be aware of.Setting up…

If you are designing your iOS app with SwiftUI, it’s essential to understand the basic concepts of Stacks, particularly HStack, VStack, and ZStack, and how to use them. In this tutorial, we will explore these three types of stacks. HStack HStack – H in HStack stands for Horizontal. This stack view arranges all the elements/views inside it horizontally. Below image has a HStack and inside the HStack we have 2 Text labels. HStack { Text (“Hello” ) .font(.title) .background (.yellow) Text (“World!”) . font(.title) .background (.green) } . padding() .background (.red) VStack VStack – V in VStack stands for Vertical.…

Learn how to set a custom working directory in Xcode to solve one of the most common beginner issue when using Vapor. What is a custom working directory?When you try to build and run your Vapor application using Xcode you might face the issue that there are some missing files, resources or Leaf templates. Don’t worry this is a very common rookie mistake, but what causes this problem exactly? 🤔Vapor is using a place called working directory to set the current environment, locate common resources and publicly available files. This working directory usually contains a Resources folder where you can…

Today we’re very happy to announce that our book Thinking in SwiftUI is updated for iOS 17, and available in both PDF as well as print. After releasing the previous edition we have held a large number of workshops and gained a lot more experience with both SwiftUI itself as well as teaching the material. Because of this, we decided to rewrite the book from scratch. The new book contains better explanations, and a lot more visuals, diagrams, and examples. During the writing of this new edition iOS 17 came out, which brought a lot of updates to SwiftUI. We…

I have one more thing to say on the relative sizing view modifier from my previous post, Working with percentages in SwiftUI layout. I’m assuming you’ve read that article. The following is good to know if you want to use the modifier in your own code, but I hope you’ll also learn some general tidbits about SwiftUI’s layout algorithm for HStacks and VStacks. Using relative sizing inside a stack view Let’s apply the relativeProposed modifier to one of the subviews of an HStack: HStack(spacing: 10) { Color.blue .relativeProposed(width: 0.5) Color.green Color.yellow } .border(.primary) .frame(height: 80) What do you expect to…

The era of having to copy-paste code from an AI chat tab into your code editor has come to an end a while ago. AI-powered coding assistants have become increasingly sophisticated, with tools like Aider showing how powerful command-line AI integration can be for development workflows. As a downside, these tools often require you to learn specific commands and syntax to communicate effectively with the AI. Claude Code builds on this foundation with a more intuitive approach. Instead of memorizing commands, you can describe what you want to do using natural language. Getting Started Download the project materials via the…

Live Activities, first introduced in iOS 16, are one of Apple’s most exciting updates for creating apps that feel more connected to users in real time. Instead of requiring users to constantly reopen an app, Live Activities let information remain visible right on the Lock Screen and Dynamic Island. Whether it’s tracking a food delivery, checking sports scores, or monitoring progress toward a goal, this feature keeps important updates just a glance away.Later in iOS 17, Apple expanded Live Activities even further by supporting push updates from the server side, which makes them even more powerful for apps that rely on real-time…

The recent “HITS in the cloud” webinar, hosted by Altron Digital Business and Microsoft South Africa, had a single message: SQL Server remains at the centre of enterprise operations.SQL is ubiquitous, recording every transaction and underpinning compliance, but it must now serve a hybrid and multi-cloud world. Azure Arc extends its abilities to wherever data lives, linking on-premises systems, other cloud providers, and edge environments.For technology leaders managing IoT and distributed data, this evolution my change how estates are monitored and secured. It could also change how legacy systems fit into digital transformation projects.Extending Azure beyond the cloudPieter le Roux,…

Call me obsessive but I notice small (sometimes exceedingly small) changes in people, places, and things. Those observations get me to thinking about why these changes were made, and especially in the case of “things” there’s usually a financial reason behind the change. Take changes in packaging, for example. I have seen firsthand the process that goes into packaging decisions. One of the most enduring “holy grails” of CPG (consumer package goods) manufacturing and marketing is finding the most economical tradeoff between the minimal amount of packaging material needed to protect a product and the most attractive packaging possible to…
