Kickstart 2.2 is out! This is a huge release on so many fronts: - You can control multiple App Store Connect and Apple Ads accounts! - You can track where your apps rank for hundreds of searches around the world! - You can create powerful, custom filters for all your keywords!

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. https://www.hackingwithswift.com/quick-start/swiftdata/how-to-count-results-without-loading-them

if #available checks whether something exists. #unavailable is the clean inverse - no more empty if blocks with all your real code hidden in the else. https://www.hackingwithswift.com/swift/5.6/unavailable

Want a TextField to be active as soon as a view appears? On iOS, combine @FocusState with onAppear to set focus automatically. https://www.hackingwithswift.com/quick-start/swiftui/how-to-make-a-textfield-or-texteditor-have-default-focus

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. https://www.hackingwithswift.com/articles/261/i-screwed-up-one-key-accessibility-behavior-and-now-i-m-on-a-mission-to-do-better

For HWS+ subscribers: StaticString is a string type that can only be created at compile time, which means no string interpolation and no surprises. It's perfect for cleaning up failable initializers when you know the value is always correct. https://www.hackingwithswift.com/plus/inside-swift/staticstring

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. https://www.hackingwithswift.com/quick-start/swiftdata/how-to-create-one-to-many-relationships

26 Oct 2026 15:50 +0000

Dictionaries with non-String, non-Int keys couldn't encode cleanly into keyed containers. The new CodingKeyRepresentable protocol bridges that gap, letting custom key types participate in Codable properly. https://www.hackingwithswift.com/swift/5.6/codingkeyrepresentable

Sunday Build with HWS+: Let's create an app designed to help kids build confidence in mathematics, with division remainders, styling polish, and a few clever SwiftUI techniques along the way. 🧮 #SundayBuild https://www.hackingwithswift.com/plus/live-streams/flash-math

Control how the keyboard reacts to scrolling with scrollDismissesKeyboard() - choose between .immediately, .interactively, or .never for precise behavior. https://www.hackingwithswift.com/quick-start/swiftui/how-to-dismiss-the-keyboard-when-the-user-scrolls

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. https://www.hackingwithswift.com/articles/262/introducing-inferno-metal-shaders-for-swiftui

For HWS+ subscribers: Swift Argument Parser makes it easy to build useful macOS command-line tools, and a JSON tidier is a great first project. This one can prettify, compress, sort keys, and write output to a file, all in surprisingly little code. https://www.hackingwithswift.com/plus/command-line-apps/json-tidy

20 Oct 2026 12:09 +0000

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. https://www.hackingwithswift.com/quick-start/swiftdata/how-to-store-swiftdata-attributes-in-an-external-file

In two hours I'm running an online workshop on building apps with AI. It's going to be *packed* – coding, yes, but also research, design, marketing, and more. Free to all Hacking with Swift+ subscribers, even if you sign up today! www.hackingwithswift.com/plus https://www.hackingwithswift.com/plus

Wow, I totally missed that over 400 apps are now using Kickstart Exchange! 🤯 It's a completely free advertising network for indie app developers, making it an incredibly effective way to find new users. exchange.kickstart.tools https://exchange.kickstart.tools

SwiftUI's Text view can format arrays, measurements, and currencies directly using the format parameter - no custom formatter needed. https://www.hackingwithswift.com/quick-start/swiftui/how-to-format-text-inside-text-views

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: Downloading data gets all the attention, but uploading Codable data cleanly is just as important. This walks through wrapping URLSession uploads with generics and Result for a much nicer API. https://www.hackingwithswift.com/plus/networking/uploading-codable-data

13 Oct 2026 15:58 +0000

I'm pleased to announce a new service for indie developers: Kickstart Signal, a feature request service you can embed in your app to track user requests, votes, comments, and more. Completely free, works on every Apple platform, and available today ✨ signal.kickstart.tools

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. 💾 https://www.hackingwithswift.com/quick-start/swiftdata/how-to-make-transient-attributes-in-a-swiftdata-model

12 Oct 2026 20:55 +0000

Everything is in place for a nice new launch tomorrow 😎

Combining opaque types with primary associated types, you can write any Sequence to express "any sequence of strings" - a constrained existential. The generics story in Swift keeps getting better. https://www.hackingwithswift.com/swift/5.7/constrained-existentials

Somewhere out there is the GOAT who designed the classic iOS 6 Passbook shredding animation. I hope they are having a great day. ✨

safeAreaInset() lets you place content outside the safe area while automatically adjusting other views so nothing gets hidden. It works beautifully with ScrollView, List, and Form. https://www.hackingwithswift.com/quick-start/swiftui/how-to-inset-the-safe-area-with-custom-content

Every polished demo you've ever watched was built multiple times behind the scenes. Making mistakes isn't a sign you're failing - it's how learning actually works. https://www.hackingwithswift.com/articles/271/making-mistakes-while-learning-swift

I'm pleased to announce v2.0 of my SwiftUI Pro agent skill! It's packed with improvements based on real-world testing of iOS 27 and iPhone Duo, and also integrates a variety of advice from Apple's own skills. Get it here: https://github.com/twostraws/swiftui-agent-skill

For HWS+ subscribers: There's more to good networking than just fetching data. NWPathMonitor and URLSessionConfiguration let you respect the user's connection, wait for connectivity, and avoid expensive requests. https://www.hackingwithswift.com/plus/networking/user-friendly-network-access

06 Oct 2026 13:39 +0000

Codable structs and enums work as SwiftData properties, but collections like [String] get stored as binary data and can't be used in predicates. Tread *carefully*. https://www.hackingwithswift.com/quick-start/swiftdata/using-structs-and-enums-in-swiftdata-models

05 Oct 2026 12:17 +0000

Long, complex type annotations got a bit more manageable. Write _ for the parts you want Swift to infer, and spell out only what matters. A small addition, but surprisingly handy when working with deeply nested generic types. 🧩 https://www.hackingwithswift.com/swift/5.6/type-placeholders

Sunday Build with HWS+: Build a SwiftData app that monitors your Xcode build times, then calculates how much time and money you'd save by upgrading hardware. #SundayBuild https://www.hackingwithswift.com/plus/live-streams/upgrade-your-mac
