iPhone Duo is coming and your agents won't have a clue how to build for it So I turned all the new documentation, APIs and developer sessions into an agent skill Grab it here: github.com/FloWritesCode/fwc… The skill will get updated as new APIs / Xcode 27.1 gets introduced

This is a really helpful way to visually understand how to build Duo layouts
Thanks for all the great feedback on Claude for iPhone Duo! Lots of folk are now optimising their own Duo apps, so I wanted to share more about how we built it, and a few of the details we sweated along the way.

- Remove IAPs from sale - Remove app from sale in all countries -> Happy deleting of old apps!
Even after removing all IAPs from sale, ASC says that my app can't be removed from sale right now. Does anyone know what's going on?

If you already have small widgets, you're in luck Because they show up automagically on the HomeView Want to opt out? Maybe hide sensitive content? I cover this and much more in the video!
There's no HomeViewKit SDK bringing your apps on the new HomeView But there are two existing APIs instead. And they don't need Xcode 27.2 or above. You can get started building for this new device today. Watch the full breakdown: youtu.be/9pJUv15Gkt4

iPhone Duo releases today! 🥳🥳 Congrats if you have your app ready on day 1. But if you don't, no need to worry. Most devices are on backorder for MONTHS. There's still time to adapt your app. Use my skill below together with Xcode 27.1's built-in skill. They'll save you tons of time!

Steve Troughton-Smith used to ask developers for their app's screenshots before major releases I loved this tradition and was always excited to share my apps Unfortunately, he left X a few years ago. I wanted to revive this tradition, hence my post below. Support each other!

I absolutely love that I can have my HomeKit accessories inside the macOS control center. I literally use this every day.

"Is there a HomeViewKit?" No. But if your app already has widgets, you're closer to HomeView support than you think. I walk through both APIs here:

I had a blast giving the closing keynote at @KotlinLeeds last week. I spoke about my journey into iOS development and how mental limitations held me back. Don't let "I can't" stop you. It doesn't matter. Do it anyways and learn how along the way. Why join the navy when you can be a pirate? - Steve Jobs, 1983
