I don't think I ever swear on social media, but this one is worth it: holy shit! A JSON-based project format for Xcode! 🤯

If you pressed "Upgrade to iOS 27" and are instead getting 26.7, congratulations: you are *not* alone 🙃 #iOS27
I know I live in a bubble, but hot damn demand for the iPhone Duo seems off the charts. (I think you’re all wrong, and should not buy one.) (Mostly so that I can buy one.)
The symbolEffect() modifier adds bounce, pulse, variable color, and rotation animations to SF Symbols with almost no effort. Multi-layer symbols can even animate each layer individually ✨ https://www.hackingwithswift.com/quick-start/swiftui/how-to-animate-sf-symbols
Replacing Bool parameters with two-case enums turns cryptic calls like stopAnimation(false) into self-documenting code like stopAnimation(.performingFinalActions). It's a small change that makes a surprising difference to readability. https://www.hackingwithswift.com/articles/172/using-two-cased-enums-in-place-of-a-boolean
I picked up a lovely piece of 3D printing for Apple fans! 🤩
There's an open-source SwiftUI agent skill that catches the mistakes AI tools keep making: deprecated modifiers, accessibility gaps, performance pitfalls. One command to install, and your AI-generated SwiftUI gets a serious quality boost. https://www.hackingwithswift.com/articles/282/swiftui-agent-skill-claude-codex-ai

First ice cream of the year - living the good life!
New on the Kickstart blog: How to make an app press kit journalists actually open. The exact anatomy of a press kit that gets your app covered – the fact sheet, the images journalists use, and a complete template to copy! https://www.kickstart.tools/blog/how-to-make-an-app-press-kit-journalists-actually-open
Kickstart had almost 3,000 downloads in week one, reached #2 in the Mac App Store Developer chart, and I’ve shipped three updates since. The mistake? I still haven’t contacted the press about it 🫠 Here’s my launch retrospective – learn from my mistakes! https://www.kickstart.tools/blog/kickstart-launch-retrospective
New on the Kickstart blog: When to call requestReview() – Apple’s rules and the timing that works. Apple limits how often review prompts appear and now gives clear guidance for using them, so here’s how to ask respectfully after a meaningful success. https://www.kickstart.tools/blog/when-to-call-requestreview-apples-rules-and-the-timing-that-works
Did you know you can build static websites using Swift code and SwiftUI-like syntax, with no HTML or CSS required? Ignite comes with built-in components like accordions, carousels, and syntax highlighting, plus a local preview server for testing. https://github.com/twostraws/Ignite
New on the Kickstart blog: What kills apps, and why it *isn’t* being Sherlocked. Apple added Dark Noise’s core job to iOS, and the app still earns over $4,700 a month. Sherlocking is a real risk, but it isn’t an automatic death sentence! https://www.kickstart.tools/blog/what-kills-apps-and-why-it-isnt-being-sherlocked
ViewThatFits tries each layout you provide and picks the first one that fits the available space 🎯 It's the easiest way to make your app look great on every screen size. https://www.hackingwithswift.com/quick-start/swiftui/how-to-create-an-adaptive-layout-with-viewthatfits

@torsteinv Although I'm a big fan (and subscriber!) of ATP, the actual inspiration is a childhood computer. (But just to be safe, I did talk to @siracusa beforehand – I don't want to tread on anyone's toes!)

Boom! If you bought my book Everything but the Code, you should check your email – not only is it the single most popular book I've ever written, but everyone who bought a copy also gets a big discount on Kickstart 😎 https://www.hackingwithswift.com/store/everything-but-the-code

Kickstart breaks down the process of building apps into clear, easy to follow steps, but then it helps you complete those steps right inside the app – finding competitors, making great marketing videos, tracking custom product page results, and so much more 🚀
What if you could build websites the same way you build SwiftUI apps, declaratively in pure Swift with no HTML required? That's the idea behind Ignite, and it works surprisingly well. 🔥 https://www.hackingwithswift.com/articles/266/build-your-next-website-in-swift
For HWS+ subscribers: Building a fully scalable, animated clock face with Canvas and TimelineView is a satisfying exercise in precise, relative drawing - and it looks great at any size. 🕰️ https://www.hackingwithswift.com/plus/recreating-ui/remaking-the-clock
One of my favorite recent additions to Swift Testing is range-based confirmations, so we can write `await confirmation(expectedCount: 5...10)`. https://www.hackingwithswift.com/swift/6.1/swift-testing-range-confirmations
Use scrollTargetLayout() with .viewAligned to snap between individual child views, or .paging to move exactly one screen at a time. https://www.hackingwithswift.com/quick-start/swiftui/how-to-make-a-scrollview-snap-with-paging-or-between-child-views
Want to customize the way links are opened? Tapping a link in SwiftUI opens Safari by default, but a custom OpenURLAction lets you intercept, redirect, or handle the URL yourself. https://www.hackingwithswift.com/quick-start/swiftui/how-to-customize-the-way-links-are-opened
FetchDescriptor gives you fine-grained control over your SwiftData queries - filtering, sorting, fetch limits, pagination, and even which properties to load. A lot of power in one place: https://www.hackingwithswift.com/quick-start/swiftdata/how-to-create-a-custom-fetchdescriptor
Sunday Build with HWS+: I mean who *doesn't* love Regex? Create a SwiftUI app that lets you experiment with regular expressions in real time, with pattern matching, group highlighting, and Swift code generation. #SundayBuild https://www.hackingwithswift.com/plus/live-streams/regexcoach
RE: @twostraws@mastodon.social
I appreciate all the replies and reposts 🙇♂️ Kickstart will be released in exactly three weeks, but you can preorder today here: https://apps.apple.com/app/kickstart-app-accelerator/id6758355178

Marketing? Kickstart will design your website for you, create TikTok-ready marketing videos for you, build your press kit, and even help you find subreddits where your audience is. It's powered by my Ignite website builder – the whole thing is in Swift.

Best of all, like all my apps Kickstart uses zero tracking or analytics. It uses Apple's Foundation Models and MLX for fully private, on-device AI, but also provides an MCP so you can connect Claude or Codex to the whole Kickstart stack in seconds if you want.

Kickstart takes the lessons from my book Everything but the Code, and transforms them into step-by-step daily tasks that help you ship – it's a complete roadmap from idea to delivery, covering marketing, competitors, building, analytics, press, and more, so you never miss a beat.
Sunday Build with HWS+: Build a live Markdown previewer for macOS using test-driven development from start to finish. #SundayBuild https://www.hackingwithswift.com/plus/live-streams/livescribe
Catch the error, *then* what? #expect(throws:) and #require(throws:) in Swift Testing return the error directly, so you can inspect it separately from the throw check itself. https://www.hackingwithswift.com/swift/6.1/swift-testing-errors-expect

✅ Mission accomplished! Most of what remains is me emailing myself important stuff so I don't forget 🫠

Competitors? Kickstart will find apps like yours, analyze their screenshots, monitor their search rankings, track their release cadence, and help you research their review sentiment so you can identify weak spots faster.

Building Hacktivate is so much fun – seeing how much people learn about computer science while also enjoying themselves is just incredible. It is *packed* with real-world knowledge, all wrapped up in practical, engaging challenges. If you like it, please leave a review! 🙌

Analytics? You get daily reports straight from App Store Connect, showing you all your sales and subscription revenue, price parity adjustments, sales funnel reports (impressions to views to downloads), and also how your Apple Search Ads are performing.
@rmondello@hachyderm.io I saw this and thought of you. https://apple.news/AOMs_ZOZTSLuHxkeLRBWq4A

Building? Kickstart takes my Control Room project and adds a ton of new features to it – the iOS Simulator gains a huge range of superpowers, but Kickstart also tracks Xcode build times, TestFlight feedback, crash reports, and more.
