Hacking with Swift

Most developers already know how to build apps, but the hard part is everything else: screenshots, reviews, App Store Optimization, launch planning, analytics, competitor research, pricing, marketing, press outreach, social posts, TestFlight management, a…

Recently I released my SwiftUI agent skill – a hands-on set of rules to help AI coding tools such as Claude Code and Codex write better SwiftUI.

If you’re building apps with agents such as Codex or Claude, this article is for you – I’m going to show you to use agent skills to make them smarter, so they write better code, faster.

If you’re writing SwiftUI with AI coding agents like Claude Code, Codex, or Gemini, I’ve written an open-source SwiftUI agent skill that helps identify and fix common mistakes they make when writing SwiftUI – things like modern API usage, performance, acc…

Building apps in Swift and SwiftUI isn’t quite as easy for AI tools as other platforms, partly because our language and frameworks evolve rapidly, partly because languages such as Python and JavaScript have a larger codebase to learn from, and partly also…

There’s a Swift mistake I see time and time again, it can cause serious problems, and it’s trivial to fix.

On October 11th I’m running an interactive online workshop to help you write better SwiftUI code, and I hope you can join!

Although the SwiftUI changes this year are a little smaller than we're used to, this year's SwiftUI update resolves a handful of common complaints folks hit when building – things that would pretty much always require us to drop down to UIKit can now be d…

Brace yourselves, folks: Swift 6.2 contains another gigantic collection of additions and improvements to the language, while also adding some important refinements to Swift concurrency that ought to make it much easier to adopt everywhere.

This year's spring release of Swift brings with it a number of welcome additions and refinements that will make small but important improvements to many projects.

Last year Apple began moving Swift and its associated projects from GitHub.com/apple over to GitHub.com/swiftlang, and the reason is becoming clear: you can now use GitHub Sponsors to support the project with a regular monthly donation, getting various re…

Unwrap Live is back for its third year, this time focusing on building great apps using Apple Intelligence.

My Black Friday sale starts today, which means you can save 50% on all my books and bundles!

Unleash your full potential as a Swift developer with the all-new Swift Career Accelerator: the most comprehensive, career-transforming learning resource ever created for iOS development.

I run a monthly newsletter about Swift, and each month I try to finish with a few thoughts based on work I'm doing, people I've met, or advice based on past experiences.

This is another good year for SwiftUI, with another batch of scrollview improvements, some welcome macOS features, remarkable control over text rendering, and more – the team at Apple have a lot to be proud of, and many developers will breathe a sigh of r…

2024 is Swift's 10th anniversary, and for the last five of those years we've had no major-version Swift updates – literally half of Swift's life has been 5.0 through to 5.10.

WWDC24 is here, which means all-new upgrades for Swift, SwiftUI, SwiftData, and more.

A huge swathe of features, changes, and adjustments are planned Swift 6, but before then we have Swift 5.10: an interim release mostly focused on fixing up data race checking at compile time, hopefully clearing the decks for Swift 6.

Swift's result builders are a powerful language feature that let us create domain-specific languages right inside our Swift code.
