Improve your SwiftUI app's performance with Xcode 26 A hands-on introduction to Xcode 26 instruments tailored towards diagnosing and fixing SwiftUI performance problems.

If you are completely new to instruments or just want to elevate your SwiftUI app's performance, make sure you don't miss my workshop next week!

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 ❤️

😫 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!

iOS CI Newsletter - Issue #79 Issue 79 of the iOS CI Newsletter, a fortnightly publication containing the latest iOS CI/CD news from the community.

I sent a new issue of the iOS CI Newsletter last night packed with content and news from the community, here's what's inside:

🖥️ Saving thousands of dollars with self-hosted runners
💨 Faster Xcode builds
🚀 New App Store Connect features
🧪 Selective Testing

Enhancements to help you submit and market your apps and games - Latest News - Apple Developer As part of our ongoing commitment to helping developers succeed on the App Store, we’re introducing new options for submitting content and updates while your app is in review, double the number of…

Apple just announced two new improvements to App Store Connect (and soon to Helm 😜) that I am super excited about:

- You can now submit additional items for review, even if you have an app version under review.
- Offer Codes FINALLY work for In App Purchases

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! ❤️

Just found out last week that OpenAI has a Prompt Optimizer for its different models, including the new GPT-5 🤯

All you have to do is paste in your prompt and the optimizer will review it and apply best practices automatically.

Xcode 26 Beta 4 adds support for opening files in external editors like Cursor!

The option will show if the file type is configured to be opened by an editor other than Xcode by default.

👀 Xcode 26 Beta 4 adds a super handy “Show View Hierarchy” button in the SwiftUI instrument!

Now you can see view updates in the context of their view hierarchy and know exactly where things happened.

developer.apple.com/documentatio...

Not sure if I am going to be disappointed, but as soon as I read this I went to download the new beta 😅

Fixed: Xcode projects with packages might not build correctly after project reloading. (155537249)

Finding the reason why this prompt was showing for Helm was incredibly tricky and involved digging into third-party libraries' code.
