🤖 Xcode 27 now lets you add custom agents through the Agent Client Protocol. That means you can bring Cursor into Xcode and use any model Cursor supports as your coding agent!

Processors are one of my favorite Nuke features. They let you run expensive image-processing tasks without impacting performance. 💪 Moving our transparent-pixel cropping logic into a processor eliminated one of Gigs’ biggest bottlenecks, deleting a bunch of code along the way.
A big part of my day, especially as I write less code, is diving into Instruments to optimize performance. To speed things up, I’m adding trace recording + analysis to Antoine van der Lee’s SwiftUI Agent Skill. SwiftUI performance tuning is about to get much easier 👀
Gigs launches tomorrow and we can't wait to get what we've been building into everyone's hands! One of my favorite features? Getting reminders when ticket sales go live so you never miss out. Funnily enough, I got one this morning! Today's your last chance to pre-order 👇
🏆 Every gig tells a story. With our new app Gigs, you'll unlock exclusive achievements as you build your concert history. Your memories deserve more than a ticket stub! Preorder the app now! 🔗 Link in the comments
🎟️ Your gig history deserves better than a spreadsheet. CSV imports are coming to Gigs: bring every concert, every show, every memory with you. Beta is open. Link below 👇
Just added support for importing your Concert Archives data to Gigs! ✨ It runs as a Background Task, so you can leave the page (or even the app) and we’ll keep importing everything.
Did you know you can trigger a GitHub Actions workflow via the GitHub API using a repository_dispatch event? Pair that with the new App Store Connect webhooks and you can react to things like an app release and automatically run tasks in your repo. Automation magic ✨
We don’t want adding concerts to Gigs to feel like admin. That’s why we’re building different ways to quickly find and pre-fill the right event details so you don’t have to type everything manually. Here’s one of them: Event Suggestions 🎟️
📆 Last chance to get your tickets for my workshop on how to improve your SwiftUI App's performance this evening! I'll walk you through real-world performance bottlenecks and show you how you can diagnose and fix them using Instruments! www.eventbrite.com/e/1821715834...

Have you ever wrapped up an instrumented recording session and then thought, “Wait… what did I do first, and when?” Start using the os_log instrument and make your debugging sessions way easier to untangle. 💪 A nice perk? You get this for free when you use Apple’s Unified Logging System.
Sooo happy to see @joshdholtz.com’s IndieDevMonday back! And what a return — with @strasser.bsky.social as the featured dev 🙌 Honored to be mentioned alongside so many talented friends ❤️ indiedevmonday.com
😫 Have you ever tried to diagnose a performance issue with Instruments and found that all symbols were missing? 💡 This happens more often than you think, but it has a very easy fix that not a lot of people know about! #iosdev

Here's another reason to stop using print statements in your code and start using OSLog instead! 💪 You can access os_log events from instruments to give you a better chance at fixing those pesky performance issues.
Back home after an amazing few days at @swiftleeds.co.uk! It somehow gets better every year — from giving a talk to karaoke nights, baby Guinness, and the best gyros in Leeds (twice! 😅). Huge thanks Adam Rush & team for another great year — can’t wait for the next one! ❤️
