Sunday Build with HWS+: Visualize sorting algorithms step by step in SwiftUI, helping learners see exactly how bubble sort, insertion sort, and others actually work. #SundayBuild www.hackingwithswift.com/plus/live-st...

AttributedString lets you attach underlines, links, and background colors to your text, all independent of the view rendering it. The real power? It works semantically with dates, names, and measurements too. www.hackingwithswift.com/quick-start/...

I help run the WWDC Community repository, which lists events taking place in and around #WWDC26. Previously we put indie app discounts there too, but the repo is so big I'm thinking to make a second repo just for that – to list app discounts available during WWDC. Useful or not?

You can control SwiftUI particle effects by tilting your head while wearing AirPods, using gyroscopic sensors most developers don't even know exist. The whole system is built purely in SwiftUI, no SpriteKit or Metal required. www.hackingwithswift.com/articles/246...

It's almost #WWDC26, which means it's time for my annual sale – you can save 50% on my books and bundles! Pro Swift, Pro SwiftUI, Everything but the Code, and even my gigantic Everything Pack! www.hackingwithswift.com/offers/wwdc2...

“Heart rate 170? I’d better ease off with this treadmill.” “Now it’s 175? Damn! I’d better slow down more.” “180?!” *hits Emergency Stop for the first time ever* The moral of this story: wear your glasses at the gym. Signed, someone who just burned 180 kcals 🫠

For HWS+ subscribers: A flock of birds looks like it's thinking as one, but each bird actually just follows three simple rules. 🐦 We can implement Craig Reynolds' boids algorithm in SwiftUI, and the results are beautiful! www.hackingwithswift.com/plus/algorit...

One of the smallest, simplest features of Kickstart is also one of my favorites – it's a menu bar extra that adds useful developer things I need every day. Another completely free feature of Kickstart!

enumerate() is SwiftData's answer to processing large datasets in batches. The concept is solid, though it's worth profiling in your own project to make sure memory behaves as expected: www.hackingwithswift.com/quick-start/...

LHR ✈️ #WWDC26 #ItBegins

✨ Make your App Store screenshots look great for free, thanks to Kickstart. It integrates my Control Room project, so you can adjust iOS Simulator settings however you want – check out how easy it is!

Swift has always let you throw, but not say what you throw. Typed throws change that - write throws(NetworkError) and callers know exactly what they're dealing with. www.hackingwithswift.com/swift/6.0/ty...

Before you start work on your next Big App Idea, take a moment to check how hard it is to rank on the App Store for your top keywords – it takes just a minute!

Sunday Build with HWS+: Build a macOS app that simulates an assembly language and virtual machine, mixing regex parsing with document-based app features. #SundayBuild www.hackingwithswift.com/plus/live-st...

✅ "Kickstart makes a developer’s life so much easier." ✅ "The app is jam-packed with features and provides incredible value - even on the free tier." ✅ "I’m in awe of the depth and breadth of tools available." Kickstart: the app that helps indie developers ship 😎

A computed property using .formatted(.currency(code:)) combined with SwiftUI's reactive body means your order total updates live as the user adjusts their tip. www.hackingwithswift.com/quick-start/...

"There is no learning without struggle" - forgetting code, hitting walls, and questioning your career are all part of the process, not signs you're doing it wrong. www.hackingwithswift.com/articles/252...

For HWS+ subscribers: Swift refuses to encode arrays of mixed protocol types by default, but a simple enum wrapper solves the problem cleanly. www.hackingwithswift.com/plus/learn-s...

If you only need a count, don't fetch all the objects just to call .count on the result. fetchCount() does the work entirely in the database and is dramatically faster: www.hackingwithswift.com/quick-start/...

Reviews for Kickstart keep coming in, and my mission today is to read and reply to every one of them – thank you to everyone who took a couple of minutes out to write something, because it really helps for new apps!

Want to count how many elements in a collection match a condition? Rather than filtering then counting, count(where:) does it in one clean step. www.hackingwithswift.com/swift/6.0/co...

Sunday Build with HWS+: Create a one-touch physics game built with SpriteKit, proving you don't need complex controls to make something fun and addictive. #SundayBuild www.hackingwithswift.com/plus/live-st...

Mesh gradients look beautiful and render fast - just specify a grid of points and colors and SwiftUI handles the rest. Animate the grid points over time for a flowing, dynamic effect 🎨 www.hackingwithswift.com/quick-start/...

Current Kickstart work: bringing back features I removed during the TestFlight because they weren't quite polished enough. Hopefully these all land in the next release: - Apple Ads support - SwiftData/Core Data explorer in Overdrive - macOS competitors apps.apple.com/app/kickstar...

The first Kickstart app update has been submitted for review – thank you to everyone who sent in suggestions! The bug fix list is long, but there are some delightful new features too. This one in particular is so much fun 😎

For HWS+ subscribers: SwiftUI's Canvas view is fast, but it's also surprisingly powerful once you start layering contexts, stacking filters, and even dropping into Core Graphics when you need to. Six techniques to take your custom rendering further: www.hackingwithswift.com/plus/advance...

Try it here – even the free features will really help! apps.apple.com/gb/app/kicks...

One-to-many is the most common SwiftData relationship type - one array on one side, an optional on the other. I'd still recommend making the inverse explicit though: www.hackingwithswift.com/quick-start/...

Did I mention I have a new app that helps indie developers make more money on the App Store? 😅 I’ve got a box full of stickers to hand out to folks who come to the Indie Fair! apps.apple.com/gb/app/kicks...

Using a protocol as a type always had hidden performance costs compared to using it as a generic constraint. The any keyword makes that distinction explicit, so you can see at a glance when you're working with an existential. www.hackingwithswift.com/swift/5.6/ex...

Thank you to everyone who emailed me with suggestions, feedback, and bug reports for the initial Kickstart release! I'm working on the first update, fixing early bugs. Feature updates will come shortly after! If you hit problems, let me know at [email protected] 🙌

In the Developer category, only one top 5 app doesn't belong to Apple, and it's Kickstart. If you want to make more money on the App Store, you should download it 🙂 (PS: You get a *ton* of functionality for free!)

There’s a Hacking with Swift+ live stream today, starting in four hours! We’re making another complete app you can ship to the App Store in no time at all – there really is no excuse for not shipping 🙂 www.hackingwithswift.com/plus

Can I make one YouTube video showing all the features in Kickstart? No! But I can certainly try to show off my favorites 😎 youtu.be/nJmzliRXg2M

My new Mac app is out today, and I wrote a blog post about it: what it does, who it's for, and what you get for free. (Spoiler: it's a lot! 😅) www.hackingwithswift.com/articles/285...

My new Mac app is out today! It's called Kickstart, and it has just one job: helping indie app developers make more money on the App Store. It is *packed* with features, many of which are completely free. Get it here: apps.apple.com/app/kickstar...

accessibilityInputLabels() lets Voice Control users activate UI controls with custom spoken commands. Without it, they'd have to recite the entire text of a view just to tap a button - imagine doing that when a stock price changes every second. www.hackingwithswift.com/articles/261...

Use @Attribute(.externalStorage) to hint to SwiftData that large data like images should live outside the main store. It handles everything transparently, just don't try using those properties in predicates. www.hackingwithswift.com/quick-start/...

Pro tip: Some APIs are fundamentally unsafe to call from async contexts. The @available(*, noasync) attribute lets you mark them as such, so the compiler will warn callers rather than letting subtle bugs slip through at runtime. www.hackingwithswift.com/swift/5.7/no...

Sunday Build with HWS+: Flashcard apps are great for studying, but making the cards is tedious. This one uses Apple's Foundation Models framework to generate study cards automatically from any text you paste in. #SundayBuild www.hackingwithswift.com/plus/live-st...

Chapter 3 of the Swift AI Playbook is out now, showing how to use text to speech to create beautiful, natural voices locally ✨ www.hackingwithswift.com/store/swift-...

Floof patrol reporting for duty!

📚 SwiftUI colors aren't resolved to specific RGB values until they're drawn, so you need the environment to extract actual components. Use resolve(in:) to get a Color.Resolved you can inspect or encode as JSON. www.hackingwithswift.com/quick-start/...

A handful of lines of Metal shading language can produce remarkable visual effects in SwiftUI ✨ Inferno is an open-source library of ready-to-use shaders that makes GPU-accelerated graphics accessible to every developer. www.hackingwithswift.com/articles/262...

For HWS+ subscribers: A few lines of Core Motion code and suddenly your SwiftUI views respond to how the device is held - screen-blended circles, spinning masks, and even 3D rotations. www.hackingwithswift.com/plus/swiftui...

Mark a SwiftData property with @Transient and it stays in memory only, never written to disk. Two rules: it needs a default value, and you can't use it in predicates. 💾 www.hackingwithswift.com/quick-start/...

Repeating the same test setup across multiple suites? Swift Testing's TestScoping protocol lets you wrap environment config into a reusable trait and apply it with a single annotation. www.hackingwithswift.com/swift/6.1/sw...

Sunday Build with HWS+: Calendar notifications are easy to miss, but alarms aren't. This app combines EventKit with AlarmKit to turn your events into unmissable alerts that sync to Apple Watch. #SundayBuild www.hackingwithswift.com/plus/live-st...

With scrollTransition(), you can control opacity, scale, blur, and hue as views enter and leave the visible area of a scroll view. www.hackingwithswift.com/quick-start/...

SwiftData handles database creation, relationship management, view updates, and CloudKit sync - all without writing a single line of database code. Build a real app with it from scratch in this tutorial. www.hackingwithswift.com/articles/263...
