My ASO tool AppShovel just got a major upgrade 👀 📋 Lists to track thousands of keywords & ranks 🤖 New API + CLI for agentic workflows ⚡ Dramatically faster across the board Now also with a 14-day free trial! 👉 Visit appshovel.com if you want to give it a spin.

Weekend project that got a bit meta: I build an agent skill that coaches you how to build a coding agent from scratch. Eight steps and you understand what's happening when these tools work. mgratzer.com/posts/from-o...

I haven't posted here in a while, so naturally I'm coming back with a blog post about AI. I know. Over the winter holidays I built an app for my kids using agents. The interesting part was figuring out how to make the agent follow my process. I wrote up what I learned. mgratzer.com/posts/forgin...

Just finished Super Mario Wonder with my kids. The joy on their faces the whole way through… Nintendo just gets it.

Ich hab einen 1.5 Stunden Workshop zu generativer KI gebastelt. Für ein nicht-technisches Publikum, das verstehen will, wie das alles so ca. funktioniert, was es kann und was es nicht kann. Bräuchte Freiwillige, die bei einem Online+Testlauf mitmachen. Nächsten Mittwoch, 21:00. DMl me bei Interesse

A small rant on the contemporary Zeitgeist for the weekend. Fuck 996. lucumr.pocoo.org/2025/9/4/996/

Als jemand der weder E-Auto noch Strom vom Dach hat, erlaube ich mir das mit folgenden Worten zu kommentieren: "Habens euch jetzt vollkommen ins Hirn geschissen?"

Our three-year-old often holds the controller upside down, finger's crossed this print helps 🤞. makerworld.com/models/1492385

Oh. I haven't recognized the port on top yet. Great addition.

This! spiess.dev/note/enginee...

He did it again! Congratulations Klemens.

And that’s how he came to realise that there are higher instances in this world, like DHL. www.bbc.com/news/article...

I’m feeling the vibe.

Need to print this out and frame it near my desk

Alright, let's make ASO affordable for everyone! 💪 Introducing AppShovel, a tool to get more organic app downloads. 🚀 ✅ Discover keywords with search & recommendations ✅ Keywords popularity & difficulty ✅ Competitor rankings The best part, it's only 5$/m! 👉 Visit AppShovel.com to get started!

Just in time for Follow Friday, we're live @swift.org. And with a post about how popular task manager Things now powers their app front to back with #swift. www.swift.org/blog/how-swi...

I can only share the sentiment. My fanboyism died a while ago, and I am moving on by viewing them as just another platform.

Our kids dodged any virus for the whole winter season, and I was proud, but pride comes before the fall.

This was a hard one. But we, as developers for Apple platforms and as humans, have a responsibility to respond. www.massicotte.org/leverage

Today, I built my first web page with the static site generator Hugo and was amazed by its flexibility. For example, adding a custom shortcode to draw inline Mermaid graphs from markdown took me 10 minutes.

We open sourced Xcode’s build system github.com/swiftlang/sw...

Here's a glossary for Swift concurrency. I've been asked about this a few times, and I finally sat down to do it. www.massicotte.org/concurrency-...

Happy Birthday 🥳

The winter downtime reading hattrick is done by rereading a book every software engineer should know: Philosophy of Software Design by John Ousterhout. It's a concise journey with practical advice on reducing software complexity. I ended up with more notes than the publisher allowed 🙃.

New content on NSHipster 😱, the best news of 2025 so far. nshipster.com

Oh, Apple TV+ is free for everyone next weekend. It's a good chance to get hooked on some of the best TV shows with high production value and excellent casts. techcrunch.com/2024/12/30/a...

I am happy to finish my second winter downtime project — ending the year with the Festive 500 challenge. It was a grind this year, as my time window for riding is late at night and indoors. Putting a checkmark behind this challenge feels excellent, though. content.rapha.cc/at/en/story/...

Yeah, I put that in all my production prompts as well. What a time to be alive. You can be damn sure, that this type of prompt snippet is also used in the medical/legal/financial expert LLM system your corp just licensed :)

I've spent the 6 months working on a new approach to shared data in Swift: Forked. Main features: - Git-like branching and merging for Swift structs - Advanced merge algorithms (CRDTs) - Macros to make structs mergeable - Sync structs via CloudKit with <10 LOCs appdecentral.com/2024/12/13/n...

Goals for #swift in 2025 published! Better concurrency, low level performance tools and java interop 🎉 Exciting stuff, lots of goodies coming to server side swift development through these :-) https://forums.swift.org/t/swift-language-focus-areas-heading-into-2025/76611

One of the must underrated views in SwiftUI might just be the `Text` view. It's a perfect example of progressive disclosure: once you dig in, you'll find a bunch of nice features! Related to the video: developer.apple.com/documentatio...

Occasionally, we see massive spikes in institutional downloads on App Store Connect — up to a 1000% increase in a single day from specific countries. Could this be spam or some scamming mechanism? Has anyone else experienced this or know what might cause it? Google wasn’t much help.

I watched the awesome talk on Passkeys by @0xtim.bsky.social yesterday. I need to learn more about it to understand how it would integrate with our authentication system. To me it still feels like a feature for super tech-savvy people. I need to test it with my dad. youtu.be/ojTDJuwfVgg?...

This is the most beautiful thread in a while, over on Mastodon. Harkank aka Erich, built a little antenna rig and wrote some code. chaos.social/@harkank/113... He's now able to read out a metric ton of sensors in his hood, including tire pressure sensors in cars. Zero info sec :D

Ok, it's time for another one of these "Swift concurrency step-by-step" posts. It explores working with types that are not Sendable. All based around reading a model from some data store. www.massicotte.org/step-by-step...

I must admit that my 3D printing experience feels this way occasionally. On the other hand, my mum will come by today to pick up the printed Christmas decorations, enjoy them, and be happy — priceless. www.reddit.com/r/BambuLab/s...
