The new StoreKit 2 supports StoreKit configuration files for local development which means, among other things, that you can test your in-app purchases without a network connection and without even submitting them to the App Store. It also provides new SwiftUI views (StoreView, ProductView, and SubscriptionStoreView) which enable a low-code implementation of in-app purchases and paywalls with ...

You can find the previous article here: Decoupled stacked sheet navigation with multiple modals in SwiftUI. In this article, we focus on the consistent handling of errors across independent modules. And thereby enhancing the user experience and simplifying the development pr...

This week I haven’t had much time to read, so it’s mostly Mastodon posts. Yeah, I’ve finally found the time to get on that train as well. Far too late it seems. The iOS community on Mastodon seems very strong, though.

SwiftData operations on background Source: SwiftData Background Tasks Use a custom ModelActor for the model to run operations on a background context. modelExecutor = DefaultSerialModelExecutor(modelContext: context) When passing objects between actors, we should use persistent identifiers, so there’s a convenience subscript on ModelActor func visit(identifiers: [Country.ID]) { for iden...
