Over the last few months, a bunch of promising leads haven't worked out. These things can take months, so who knows? But in the meantime, I have room for more work.

Been working with a client for 3 years — their iOS app is 10 years old, half of it still in Objective-C.
I sneak in Swift concurrency, property wrappers, etc., but honestly sometimes I feel like a dinosaur 🦕
Anyone else stuck in a mix of old and new? 😅

If you haven't heard, there's a new Bluesky client coming this summer
➡️ @phoenix.tapbots.com from the makers of Tweetbot and Ivory.
Our team is very eager to give it a try. It's always exciting to see the Bluesky ecosystem growing.

This is why I’ve never played the SEO game, and (other than a weeks long experiment with AdWords in 2003) have never accepted pageview-measured ads on Daring Fireball. The way that SEO-driven ads would — not *might*, but *would* — corrupt both format and content was obvious to me.
this is the internet Google created where everyone is trying to keep page time up, word count above a certain level, etc. it fucking sucks and it’s just because everyone is trying to game the algo to make their little ad rev pittance
I wanted to know if Kraven the Hunter had a post credits scene so I found an article about it.
There were TEN paragraphs before I got a yes or no answer.
This was one of them. Do they really think I needed this beforehand?

What does it mean for something to be Turing complete?
I answer this question, and more, through a series of fully interactive Turing machine simulations! Play, pause, step forwards and backwards, and even write your own Turing machine programs in my latest blog post.

If you’re taking a programming course, divide it into sections and take breaks. After completing the first section, take a few days off and practice coding on your own. Let your brain assimilate what you’ve just learned. Then, move on to the next part of the course.

I got a thing working! Multiple cursors for `NSTextView`.
Library is actually text system-agnostic and `UITextView` isn't too far behind. Not "done" quite yet, but quite far along. And has some of the pieces in place to support very large numbers of cursors.

When I think about folks starting their journey in iOS development, I find it can be tricky to navigate all the available materials and identify what is fundamental and essential. I believe Apple Pathways is a good resource for this purpose: developer.apple.com/pathways/?ci...

What’s the difference between any and some in Swift?
Any and some are both keywords that can be applied to existential types. Learn about their differences and similarities in this post.

When I think about 3 best iOS development changes in recent years:
1. Previews: no need to restart project to see UI changes.
2. Swift Data: been using in my side projects only, but feels much lighter than Core Data.
3. SwiftUI + Observation. I like it for almost all cases. Maybe except drag & drop.

I’m currently working on an iOS app for a bank, focusing on a Wallet Extension, a tiny utility that integrates the iOS Wallet with my app. If you do something similar, note that Wallet Extension disappears in iOS 18.1 but hopefully will return in 18.2 as some folks report: tinyurl.com/3u7yp462
