Apr 22   READ IN APP   A few weeks ago, I asked, “How can I improve the newsletter?” I got a bunch of emails with ideas. Thank you! 🫡 A few people mentioned that we should add a indicator (what level of development knowledge is required) next to each piece we share, whether it’s for junior, intermediate, or senior developers. So we did that! ✅ A few others mentioned that it would be nice to have a community. So below, you’ll find a poll. Please vote. 👇 P.S. If we talk about a paid community, it would come with many benefits like well-known developer appearances, tips, unheard stories, and more. POLL Do we need a community? Yes, but only FREE I would join a PAID one too! I'm not interested at all! Connect with the "Those Who Swift" team - Justas Markus & Anton Gubarenko 👋 Today we have a new partner: Hostinger! 🚨 It comes with great deals for OpenClaw and VPS hosting. You can deploy OpenClaw on Hostinger with one-click deployment, pre-integrated AI tokens, and full control over your sensitive data and chat logs. It also offers 24/7 support and dedicated performance. OpenClaw Hosting Deal! One of the fastest virtual private servers, now with a 70% discount. Rock-solid performance and ready to deploy! VPS 70% OFF Deal! Associatedtype In Swift Explained - A Complete Guide With SwiftUI Examples Sagar Unagar explains associatedtype through the distinction that generics choose a type from the caller side, while associated types let the conforming type decide it. Read more.📍Level: Intermediate SE-0526: WithDeadline The Swift Evolution review introduces withDeadline, a concurrency API that cancels work when an absolute deadline passes, while still waiting for the operation to finish cooperatively rather than force-stopping it. The most debated part is the API shape itself, with much of the discussion focused on naming, typed error wrapping, and whether the cancellation behavior should be made more explicit in the name. Read more.📍Level: Advanced A Reusable Spotlight Onboarding Component In SwiftUI Artem Mirzabekian builds a reusable SwiftUI onboarding spotlight that can highlight any view, show contextual guidance, and keep working across scroll views, navigation, sheets, and safe areas. The most useful part is the implementation approach: anchors and PreferenceKey make the solution flexible without dropping into UIKit-style overlay hacks. Read more.📍Level: Intermediate Building A Draggable Bottom Sheet In SwiftUI Natascha Fadeeva shows how to build a draggable bottom sheet with SwiftUI’s native sheet and presentationDetents, while still allowing scroll coordination and interaction with content underneath like a map. The most useful detail is that you can combine custom detents, disabled interactive dismissal, and background interaction for a bottom-sheet feel without building a fully custom container. Read more.📍Level: Intermediate Tim Cook To Become Apple Executive Chairman, John Ternus To Become Apple CEO Apple announced that Tim Cook will become executive chairman and John Ternus will become Apple CEO on September 1, 2026, marking the biggest leadership change at the company since Cook took over in 2011. The key detail for developers and the industry is that Ternus comes from hardware engineering, which may keep Apple’s product-first direction firmly in place during the transition. Read more.📍 Dotted Background Effect In Metal Victor Baro breaks down an interactive dotted background shader step by step, showing how SDF circles, fract(), floor(), and touch-driven uniforms combine into glow, attraction, and repulsion effects. The most useful part is the mental model: dots are not moving objects, just pixel math, so the motion comes from shifting each dot’s logical center before rendering. Read more.📍Level: Advanced FormatStyle Guide Chris Eidhof introduced an interactive browser-based guide to Swift Foundation’s FormatStyle APIs, with live examples for numbers, dates, measurements, and parsing. The most useful part is the SwiftUI angle, since the guide also shows how these formatters plug into real app code instead of staying as isolated API docs. Read more.📍Level: Intermediate Five Things I Learned About Making AI Coding Agents Actually Work Ivan Magda argues that better results from coding agents usually come from better scaffolding, not from switching models. The most useful takeaways are practical ones: keep instruction files short, structure projects so agents can navigate them, start fresh sessions earlier, and give the agent a way to verify its own work. Read more.📍Level: Advanced Introducing Claude Opus 4.7 Anthropic says Claude Opus 4.7 is now generally available, with stronger performance on difficult software engineering tasks, better vision, and more reliable long-running work than Opus 4.6. The practical detail is availability: it is live across Claude products, the API, Amazon Bedrock, Google Cloud Vertex AI, and Microsoft Foundry, with pricing unchanged from Opus 4.6. Read more.📍 Introducing Claude Design By Anthropic Labs Anthropic says Claude Design lets teams create prototypes, slides, one-pagers, and other visual work through conversation, with support for inline edits, design systems, and exports to formats like PPTX, PDF, Canva, and HTML. The most interesting part is the workflow bridge: once a design is ready, it can be packaged into a handoff bundle for Claude Code, making the jump from idea to implementation much tighter. Read more.📍 Codex For (Almost) Everything OpenAI says Codex is moving beyond coding into a wider developer workflow, with computer use, image generation, memory, repeatable automations, and support for tools like GitHub reviews, SSH devboxes, and browser-based iteration. The most useful part is the broader scope: it is starting to feel less like a code assistant and more like a workspace agent that can carry context across the full software development lifecycle. Read more.📍 SwiftUI: Refreshable Task Cancellation Article explains a subtle SwiftUI trap where .refreshable can cancel its own work if state changes trigger a redraw too early. The most useful part is the two-fix breakdown: publish one final state update when possible, or wrap the refresh logic in a separate task when incremental updates are required. Read more.📍Level: Intermediate try! Swift Tokyo 2026 Videos try! Swift is one of the leading international conferences for iOS developers focused on Swift. It gives developers from around the world a great chance to explore the latest trends in Apple platform development and learn from some of the best voices in the community.
