Those Who Swift - Issue 208
Weekly note ✏️AI, vibe-coding, WWDC—there’s no shortage of trends in tech. But at the end of the day, if you want to build solid software, you either go Indie (a whole different world, which we’ll cover later) or work for a company. And when you work for a company, beyond your hard skills, you need to keep an eye out for red flags that should make you reconsider your choices early on. Some common ones include: 🚩 Unrealistic goals – “We’re going to disrupt the market!” (without a clear plan). Value yourself. Don’t let a company take advantage of you beyond what’s outlined in your contract. Honestly, I’ve been wondering—companies can fire employees if they fail to do their job. Wouldn’t it be fair if the reverse applied? If a company consistently fails to meet its promises, shouldn’t the leadership step down for mismanagement? Food for thought.

Swift Around the Web 🌐Modern URL Construction in SwiftAfter a two-year hiatus, John Sundell returns with an insightful article on constructing URLs in Swift. He explores leveraging Foundation's latest URL APIs alongside Swift features like macros to streamline working with both static and dynamic URLs. Sundell introduces a custom initializer for static strings and demonstrates creating a compile-time validated macro to ensure URL integrity, enhancing code safety and clarity. What a return! Introducing swiftly 1.0Chris McGee (from Swift Foundation) introduces swiftly 1.0, a Swift version manager designed to simplify the installation, management, and updating of Swift toolchains across various platforms, including macOS and Linux. This tool allows developers to effortlessly install new versions, switch between multiple installed toolchains, and experiment with nightly snapshots or older releases. Swift 6.1 ReleaseSwift 6.1 brings improved concurrency support, better Objective-C interoperability, and productivity enhancements like trailing commas in various list types. The Coding 👨💻SwiftUI Craftsmanship: State ManagementDanny Bolella delves into effective state management in SwiftUI, emphasizing the importance of understanding and utilizing tools like Does AsyncStream Replace Combine? No.Michael Long examines the roles of Other cool stuff 🧰SwiftData Uncovered: My Learnings and InsightsIn this article, Naren Krishnaa explores SwiftData, highlighting its streamlined approach to data persistence compared to Core Data. He delves into three core components: SwiftUI Grid, LazyVGrid, LazyHGrid Explained with Code ExamplesAntoine van der Lee explores SwiftUI's grid layouts, focusing on Building a Dependency Injection FrameworkNatascha Fadeeva introduces a lightweight dependency injection container for Swift. She covers service registration, resolution, and managing object lifetimes, showing how DI improves modularity and testability. A great guide for structuring Swift apps efficiently There is no Vibe EngineeringSergey Tselovalnikov challenges the idea of "vibe coding," where developers rely on AI agents to generate code. While useful for prototyping, he argues it lacks the depth of real software engineering, which involves scalability, security, and maintainability. AI can assist coding, but it doesn’t replace true engineering. Apple News 🍏WWDC 2025Apple has announced that the Worldwide Developers Conference (WWDC) 2025 will take place online from June 9 to 13, 2025. The event will unveil the latest Apple tools, frameworks, and features, offering developers opportunities to enhance their apps and games through video sessions hosted by Apple engineers and designers. Attendees can engage with Apple experts in labs and connect with the global developer community, all at no cost. Instruments TutorialsApple’s Instruments is a powerful tool for analyzing app performance, identifying memory leaks, and optimizing CPU and resource usage. The tutorial walks through key profiling techniques, such as detecting slow code paths, monitoring memory allocation, and analyzing thread activity. It also covers best practices for improving responsiveness and efficiency in iOS and macOS apps. By mastering Instruments, developers can fine-tune their apps for a smoother user experience. AI 🤖Krea.AI 3D-models GenerationKrea.ai has introduced a new 3D tool that leverages advanced AI models like Hunyuan 3D and Trellis to generate high-quality, textured 3D objects in seconds from text or image prompts. This tool simplifies the creation of 3D assets, making it accessible for designers and developers to produce detailed models without extensive manual effort. Tutorials 📒Detecting Barcodes on an Image with the Vision FrameworkMatteo Altobello demonstrates how to utilize iOS 18's Video 🎥Swift vs. Objective-C Protocols: Friends or Foes?Yakov Manshin explores the interoperability between Swift and Objective-C protocols, focusing on their compatibility and challenges. He discusses how Swift's protocol-oriented programming aligns with Objective-C's dynamic nature, highlighting potential pitfalls and best practices for integrating protocols across both languages.
