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.

It’s been a while since I last wrote something, so having my first article back featured in iOS Dev Weekly really means a lot ❤️

Sooo motivated to keep writing now 🙏

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.

If you want to get an insight into my debugging process, read my latest article:

A Peek into My Debugging Process (With Real Examples) A guide to making the best use of the tools available to you to fix bugs in your apps and get to the root cause of the issue in record time.

I know it has been a while, but I have finally written a blog post again! ✍️

This time I share how I debug real-world issues in my apps — from invisible crashes to unexpected system prompts — and the tools that I use.

📬 New issue of the iOS CI Newsletter drops tonight!

I’m diving into AI-assisted development and why solid tests + CI/CD matter more than ever.

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!

🎨 Xcode 26 Beta 3 now adds support for setting Icon Composer icons as alternate iOS icons!

💨 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.

Filing Apple Feedback isn't a waste of time. Eric Dorphy has submitted over 1,000 reports, and his experience shows small actions really add up, even if you don't always see an immediate result!

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!

📬 I'm sending a new issue of the iOS CI Newsletter this evening and I will be sharing my thoughts on Apple feedback along with important insights on why you should continue filing feedback!

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.

This is pretty neat!

In Xcode 26, you can now generate comments for String Catalog keys using Apple Intelligence and change the key's name in the code + catalog within the refactor options

Being able to chat with a tab while giving context from other tabs you have open is such a 🔥 feature for a browser...

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.

Best way to kick off the last year of my 20s! ❤️🎂

It does! But it is limited to the 26 versions…

I bet you regret sharing an office with me now 🤣🤣

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.

The moment we have been putting off for about a year has finally come I guess... 🙈

Making tools for Foundation Models is just ridiculously easy, and the fact that you can just any of your app's code is just 🔥

Such a neat way to feed context into your LLM session

For everyone using Foundation Models to categorize content, there is a very useful use case for the model, but you need to know it is very limited!

It only supports English language and can not be used alongside tools 😔
