I think we all love the reduced boilerplate we get from being able to assign a value directly from a switch while assigning it directly to a value. But sometimes one clause creeps in that needs more logic. With many cases, adding return anywhere is laborious and also unnecessary: #swift #xcode

Another way of adopting your layout to iPhone Duo inner screen is using content margins. The contentMargins view modifier allows us to shift a particular type of content in the view. swiftwithmajid.com/2024/04/23/c...

I’m looking to stay up to date on AI without having to deal with X. What are my options?

Alignment guides are a powerful but often underused part of SwiftUI's layout system. They let us describe relationships between views using meaningful points in their content, without frame measurements or fixed offsets. I wrote a post explaining them in detail: nilcoalescing.com/blog/Alignme...

The shaman of Bad Dürrenberg are the remains of a 25-35 year old woman, who was buried 8600 to 9000 year ago in Germany. Around her, were the remains of an extraordinary head-dress, made from the bones and teeth of different animals such as deer, wild boar, crane and turtle.

Apple now says: don't split large SwiftUI views with computed properties or @ViewBuilder helpers if you want real performance wins. A computed property still lives inside the parent body. Same boundary. Same re-evaluation. #swiftlang #iosdev #swiftui emredegirmenci.substack.com/p/splitting-...

I always do this, never leave me guessing.

Control Center tells you an app is using your mic right now. Not which mic, not what used it a minute ago, not for how long. Capture Inspector does: every app per mic, with the process, PID and timing, live and recently used.

Here's an easter egg in the new Lego Batman that I think all of you will REALLY appreciate. It's so good, I had to make a video.

“Friends that use Windows or Android” Well hypothetically

I just heard a recent hire at Uber got fired again after they needed more money because they blew their 2026 token budget in April. What a fucked up time we live in. The guy they hired and fired is what people refer to as a 10x developer. No way a bunch of tokens could replace that.

Apple updated its Human Interface Guidelines for Sheets on March 24, 2026 to add guidance for button placement in the toolbar. "In iOS & iPadOS, the Cancel button belongs on the leading edge of the top toolbar." Time to update my apps 🙂 Documentation: developer.apple.com/design/human...

I can't stop laughing at this post. It's perfect.

How Mitchell Hashimoto (creator of Ghostty, founder of HashiCorp) got good at using AI tools for coding + work: "I was forcing myself to figure out how to prompt the agent to produce the same quality result as mine. Even though I was working much slower because it was more than double the work."

"Tools I Love: xcrun simctl io booted recordVideo" A handy lil command line tool to visualize changes in my PRs that I use regularly.

Today I wrote an app I've been dreaming about for stage managers, but never had the month I estimated it would take to build it. I did it in 6 hours. That 6 hours also included making my kids breakfast, driving them to school, chatting with an artist at the theater.

"The blood was only ever a means to an end," the vampire confessed in the interview. "To what end?" the reporter asked. "Blood carries vigor, life force, vital energy. That's what we feed on." "So how do you get it, if not through blood?" "These days, we make doom scrolling apps to drain it."

Anthropic has bundled Claude Code features into a more user-friendly interface called Cowork. Looks good. Requires a Max subscription (💰) for now so I can’t try it. Pretty good name, though not as good as Copilot and Codex. Still, I like where Anthropic is going with this.

Best post-ride gift shop item ever. At the new Danse Macabre ride in the Efteling theme park they sell snow globes featuring a black cat and dead tree, showing bats and black snow when you shake it.

Interesting post, I'm trying Codex currently to see if it helps. Often I just want Claude to build something and then walk away to do something else, only to discover that it got stuck 10 seconds in.

I've always felt that having one 16" screen was enough for me to work on. An extra screen never felt like a necessity. But I really would like to have the screen estate now to monitor running agents while doing else myself.

This bit from the Amanda Askell interview is interesting. In my recollection, most people on Twitter (in my bubble at least) were really positive and excited about Claude 3. The only negative narratives about Claude I remember seeing came from Anthropic itself.

Would love to get me one of those, but I already have a bunch of originals in storage and a RetroPie. I can't imagine going for the translucent ones, the full sized beige / khaki / brown one really helps bringing back the feel of the original.
