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

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:
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

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

The app preview video got accepted first, so naturally I submitted a product page optimization with it for review Back to 3 items waiting for app review 😂
LaunchBuddy currently has three submission waiting for review: - macOS version 7.2.0 - app preview video for iOS - new IAPs I never had three submissions in app review for a single app 😂

I used to have a macOS app on the App Store to show a list of SwiftUI font sizes for my own reference I always got confused with callout, subheadline, and footnote But I removed it from sale, because this is also baked into @LaunchBuddy_App (has been for a few years)
