One day I may write an article about it. Until then, here are some tips about #SwiftData & #CloudKit.

Trying something

Today’s theme

It was time for an upgrade.

I really need to stop spilling coffee on my desk.

Have a great day!

I’m starting a monthly newsletter! It’ll include #SwiftLang & #SwiftUI tips, project updates from our team, and special discounts on my books. You can sign up now on my website, and the first issue will be sent at the end of January: nilcoalescing.com/newsletter

Started 2025 with some UIKit. LazyVStack got the better of me. I couldn't figure out how to avoid hangs for my calendar view (with data for each day) 😔

SwiftUI Previews with #CoreData is easier than ever thanks to the new PreviewModifier protocol introduced at this year's WWDC. I've mistakenly always thought it would only work for #SwiftData but it turns out it's perfectly fine for Core Data too! 😀

Relationships in Core Data and SwiftData efficiently manage data by maintaining associations with deletion rules and optimizing memory with lazy loading. but handle to-many operations in SwiftData carefully to avoid performance loss fatbobman.com/en/posts/re...

I‘m new to AppIntents. And this blog (sowenjub.me/writes/local...) helped me (after 3h) figure out how AppShortcutsProvider is getting it‘s Localized Strings.

In SwiftUI, updates to a parent view's size or position are passed down to child views all at once, which can disrupt animations. `geometryGroup` allows these updates to be delivered gradually and animatedly to child views. fatbobman.com/en/posts/ma...

I have request! Can you go help out @kawamataryo.bsky.social on his big Product Hunt debut today? He's battling a scammer that's trying to trick people into using a fake Sky Follower Bridge and could use your help proving that his is the OG by winning on Product Hunt! 🙏🏻👇🏻🏆

Thanks to #SwiftUI 's powerful graphics APIs, I am this close to retiring my copy of Photoshop CS6 for good 🤏

Second time my app gets rejected because I offer users to contact me and ask for an Educational Discount. They fill a form, I send an offer code if it looks legitimate. But the reviewer (who didn’t go through the whole process) claims I use an external mechanisms to unlock purchases 😤

🤯 Why isn’t this on by default?

Hey! I make iOS apps for myself that sometimes other people like too. Barcodes is a privacy friendly loyalty card wallet, with a bunch of handy features like iCloud sync and sharing! Supports Apple Watch, Apple Wallet and Home Screen widgets. Check it out! trybarcodes.com

Now that I have a bigger reach, I’d like to once again call on #SwiftUI and #Swiftlang developers interested in atproto: 1) What would you like to see with ATProtoKit to help you better with integrating it into your SwiftUI apps? 2) What pain points do you have currently?

So, which robotic arm should I buy to get started?

🤩 I was wondering why it didn’t exist. Turns out it does!

Am I the only one that didn't get the memo that as of iOS 16.4, you can disable UIHostingController's safe area insets without any swizzling or private APIs?

Calling all designers on Bluesky! Let’s see who’s here 👇

Lets see if this site is a great at finding talented developers as that dead bird site used to be. We're hiring in Cupertino, San Diego, Seattle and Vancouver BC for a bunch of different roles. jobs.apple.com/en-us/search...

I've built an internal tool to get #AppleSearchAds popularity 📈 But I need to login with 2FA every few hours to get the cookie required to use the endpoint 😞 Does anyone know how to make this easier? Can I use an app-specific password? #AppStoreOptimization #ASO #ASA #iOSDev

People who cross-post, do you also cross-reply when you spot a cross-post?
