How closure-based service wrappers protect your app from vendor lock-in and make third-party SDKs testable.

Ready to add AI to your iOS apps without privacy concerns or cloud dependencies? Apple Foundation Models brings powerful on-device language models to iOS 18+. This tutorial shows you how to build AI-powered apps with structured data generation, covering basic…

Swift + SwiftUI + Type-Driven Design + Swift Effect.

Learn how to leverage modern Xcode features like String Catalogs and Asset Symbol generation to achieve compile-time safety for your resources without external dependencies.

Why NSManagedObjectContext no longer triggers concurrency errors in Swift 6.2? The real change lies in Core Data’s SDK import semantics, not the compiler itself. NSManagedObjectContext is now marked with NS_SWIFT_SENDABLE and NS_SWIFT_NONISOLATED in Xcode…

Swift is designed to be the language you reach for at every layer of the software stack. Whether you’re building embedded firmware, internet-scale services, or full-featured mobile apps, Swift delivers strong safety guarantees, performance control when you…

Greetings, traveler! The application I joined had a long history. Development started around 2015, with a large Objective-C codebase that gradually evolved as different teams took ownership over the years. At some point Swift was introduced, but the transition…

Greetings, traveler! SwiftUI is great right up until you need to touch something it doesn’t expose. Maybe you want to tune scroll behavior, read an internal layout value, tweak a gesture recognizer, or integrate with an existing UIKit-based subsystem. In…

I wrote a blog about how to process Apple HDR Gain Map using both ImageIO and Core Image approaches:

What I learned setting up a large-scale iOS codebase so that AI coding agents can work in it effectively, from hierarchical documentation to executable skills.

If you're using @FetchRequest with a Share Extension, it will never pick up cross-process changes. Here's what actually works.

Extract shared API models into a Swift package that both your iOS app and Vapor backend consume. One source of truth, compile-time guarantees, zero duplication.

Add JWT-based authentication to the Vapor backend. Build login and signup screens in SwiftUI. Store tokens securely in Keychain using the closure-based service pattern.

In my previous article, I discussed the current reality of Core Data in today's projects: it hasn't disappeared, and it still has unique value, but the disconnect between it and modern Swift projects is becoming increasingly apparent. In this article, I will…

SwiftUI has been around since 2019. Apple has given us dozens of WWDC talks about it. And yet most developers — even experienced ones — still get tripped up by the same things: These aren’t ... <a title="The AttributeGraph – The Engine Behind Every SwiftUI…
