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.

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.

Friendly reminder that the LocalizedError protocol has more than just `errorDescription`. You can provide more context such as how the user might recover from the failure, which can come in super handy!

💨 One of my favorite patterns for syncing data with a backend:
Diff what’s changed → execute the necessary requests in parallel. Fast, clean, doesn't make unnecessary calls and is easy to maintain.

Spotted this local network alert in @helm-app.bsky.social — despite not scanning the network at all 🫠
After some digging, the culprit was using ProcessInfo() to grab system info for feedback purposes. Might be worth checking usages of ProcessInfo in your app too!

Xcode 26 can use the AI model of your choice to document your code!
I still had to tweak the results a fair amount, but I guess different models might be produce better results.

Foundation Models won’t always be available to every user — maybe their device or locale isn’t supported, or the model hasn’t finished downloading.
Luckily, SystemLanguageModel has handy properties to check if it’s supported and ready — and why it might not be so you can handle it gracefully.

In Xcode 26, the new SwiftUI instrument template can NOT be used on the simulator.
Maybe a bit of a hot take, but I like this and think it's a great idea! You should run instruments on device regardless to get the most accurate results.
