It’s been interesting to watch the shift in the discussion around AI tooling this past week in the iOS community. It’s gone from mainly that these tools are useless to how impressive they are.

Pretty happy with the progress on my side projects this year so far. I’ve intentionally tried to get something done each day, no matter how small, which seems to work better for me, instead of trying to bite off large chunks whenever I feel like I have the time.

What a great read, both visually and in content. This is actually one of the changes I didn’t expect to appreciate as much as I do in the new Reeder.

Blacksky @blackskyweb.xyz now has its own servers running the network
This means they're able to run their own feature development and moderation policies, while still connecting to Bluesky through the shared Atmosphere network!

Working on some final tweaks to the model types before my first CloudKit schema deployment to production. I always find it easy to get stuck on things like this, you want the naming to be solid and to try to anticipate all future needs.

After using Reeder (Classic) for 15(!) years, I’m finally giving the new version a try. I’m not completely sold on the new way of browsing feeds yet, but wow, what a beautiful app!

First time I’ve noticed the Daring Fireball reference in the Xcode project file diff when you add a markdown file.

It's almost like the App and Play Stores have never been about moderation or keeping users safe, they've been about control and taxing developers wherever possible

Did you know that you can browse SF Symbols directly inside Xcode? 🤨
All you need to do is click on "View > Show Library", then open the 4th tab.
And it can be even smoother by using the shortcut ⌘ + ⇧ + L 👌
