Swift 6 is keeping me on my toes today. 😅 My side project [Snowmate] is hitting a weird crash on Line 26 specifically under the Swift Language Version 6, but works fine in 5. Seems like Core Motion and the new concurrency checks aren't playing nice. Anyone else seen this?

Hey iOS devs! What are you using for in-app user feedback lately? Looking for recommendations for my current project. Would love to hear your pros/cons on different tools.

Hi folks, do you like listening to online radio while at your computer? I do, and I created a small, free iOS app for this. Give it a try if that sounds like your thing. Enjoy! 🎧 apps.apple.com/pl/app/radio...

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. I help teams adopt Swift 6/Concurrency with confidence and success. More info about me here: www.massicotte.org/consulting

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.

I’m aware that the end of January might not be the best time for cycling but I’ve just released version 2.0 of my app. If you like cycling, feel free to give it a try: bikemind.app

Do you plan to learn how to write tests in Swift? It's great opportunity to learn and to help: @twostraws.bsky.social is looking for as many folks as possible to help contribute tests for Ignite - his open source project. I plan to join, do you? :) See: twostraws.gumroad.com/p/hacking-wi...

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.

If you're searching through developer.apple.com/documentation for some introductory materials, pay attention to such symbols. These are usually very well written interactive tutorials

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. github.com/chimeHQ/IBeam

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...

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 don't adopt a new Apple technology until it's been out for at least a year" said a guy who works with Apple platforms for +25 years. Love it. Very interesting talk with Matt Massicotte about Swift Concurrency: www.youtube.com/watch?v=oMg2...

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
