What are the Domain Objects in React/Nextjs? It's an abstraction that we need. In a nutshell, these are objects that represent our business. They come from your database/API. Examples: Key domain objects in banking: (things my team deals with at Erste Digital) ↳ BankAccount, Payment, Transaction, Credit Card, Customer. In media streaming (e.g., Netflix): ↳ Movie, Series, Episode, Subscription, Consumer. In hospitality: ↳ Booking, Hotel, Room, KeyCard, Guest. It's a good idea to always have Domain objects and operations on them abstracted away from the rest of the code. Because these will be highly reusable: (across the React/Nextjs codebase) - Hotels are within the accommodation search feature - But a single hotel is also in the guest trips feature - And in the guest reminder/notifications feature Here's what such a Service has: ✓ It contains the shape of the Domain object ✓ Provides operations on the Domain object ✓ Resolves Domain object business logic ✓ Fosters reuse across the codebase ✓ 100% covered using unit tests ✓ Retains high cohesion Business requirements change. React components change. Styling changes. Your Domain stays the same. Have it separated. // TODO: Repost to your network ♻️ P.S. What are the key domain objects in your project/business at work?⁣ ⁣

Claude is now generally available in Xcode!!! "Developers can now connect their Claude account to Xcode 26 to power coding intelligence features with Claude Sonnet 4. Xcode is Apple's integrated development environment (IDE) and offers the tools you need to develop, test, and distribute apps for Apple platforms. This integration lets developers use Claude's coding capabilities directly in their workflow, accelerating app development for Apple platforms."

While new Xcode projects come with the Swift 5 language mode, main actor isolation, and approachable concurrency by default, SPM packages do not. To enable the Swift 5 language mode you need use Swift settings. I cover this and much more in Practical Swift Concurrency: https://lnkd.in/eMTx7wM5

Expo SDK 54 introduced React Native precompilation, cutting uncached iOS build times by almost 10x. This is a big improvement, but testing with a larger app (80 dependencies) shows there’s still room to make builds even faster—possibly another 2x. Take a look at the chart for details. #ReactNative #Expo #iOSDevelopment #IOS #RN #Development #Performance #React #Development #MobileDevelopment #App #JS #DevTools #JavaScript #AppDevelopment
