Inside: LTV, conversion rate and refund benchmarks by plan, price, and region, Adapty Pricing Index, top-performing paywalls & A/B test results (based on 70k+ paywalls). It’s a quick read with a lot to unpack your roadmap for the next 3 months. Swift Around the Web 🌐Windowing on iPadOS (Or How I Learned to Love the Backlog Bomb)Danny Bolella dives into iPadOS 26’s powerful new windowing system—complete with resizable, tileable windows, a Mac-style menu bar, pointer support, and even Exposé for multitasking. He explores how SwiftUI now supports multiple windows, showing techniques to open, position, and manage them natively across iPad and Mac platforms. Handling WebView Navigation in SwiftUIArtem Novichkov demonstrates how to use the new WebView and WebPage APIs in SwiftUI for URL loading, progress tracking, and redirect handling. He walks through adding navigation via Toolbar items which controls the history of requests. Coding 👨💻Creating and Customizing the Menu Bar of a SwiftUI AppMatteo Altobello demonstrates how to use .commands(content:) in a WindowGroup to add custom menu items—complete with keyboard shortcuts—on macOS and iPadOS 26. You’ll learn to define new CommandMenu sections, integrate built-in command groups, and dynamically enable menu options by observing focused scene data (e.g., deleting a selected item). Presenting Secondary Windows on macOS with SwiftUIGabriel introduces the Window scene API in SwiftUI, enabling macOS apps to create additional standalone windows beyond the main WindowGroup. A concise, practical guide to building richer desktop app experiences. Apple 🍏EU App Store Store Services TiersApple has introduced a two-tier system for App Store Store Services in the EU. By default, apps use Tier 2, providing the full range of App Store features (distribution, personalization, analytics, marketing). Apps promoting or communicating offers can opt into Tier 1, paying a reduced services fee but losing capabilities like automatic updates, editorial curation, performance insights, and ratings/reviews. Design 🎨Icon Composer NotesJohn Brayton shares his findings from WWDC on using Apple’s new Icon Composer for crafting multi-layered app icons. He walks through a step-by-step process—from preparing PNG layers instead of SVGs, to configuring colors for light, dark, and monochrome modes, grouping effects, and saving your output as a .icon package. Other cool stuff 🧰Swift Macros in the Wild: Building Reusable SwiftUI Views with @expressionWesley Matlock shares how he used Swift’s new @freestanding(expression) macros to eliminate boilerplate in his PushTo100 SwiftUI app. A hands-on example of how compiler-driven macros can simplify SwiftUI workflows with cleaner syntax and better performance. Supporting Reduced Motion Accessibility in iOSNatascha Fadeeva explains how to honor the system’s “Reduce Motion” setting in SwiftUI, using AI 🤖Grok 4 & Grok 4 Heavy LaunchElon Musk’s xAI has released Grok 4, their most advanced AI chatbot yet, alongside Grok 4 Heavy, a multi-agent version available via a $300/month SuperGrok Heavy tier. Despite impressive benchmark performance, the launch was overshadowed by controversies: recent tests revealed the model occasionally echoes Musk’s own viewpoints when queried on sensitive topics. Introducing Kiro: Agentic IDE for Spec‑Driven DevelopmentKiro is a new AI-powered IDE from Amazon that guides you from prompt to production with spec-driven workflows, turning ideas into structured requirements, designs, and implementation tasks. Built on a Code OSS core, Kiro supports Mac/Windows/Linux, integrates with VS Code settings and plugins, and is free during its preview phase. Tutorials 📒FoundationModels: Basic Prompting for an iOS Reader AppArticle walks through building an iOS reader app powered by Apple’s on-device Foundation Models framework. It’s a full demo of balancing privacy, usability, and Swift-native AI—with practical tools like model availability checks, tool calling, streaming outputs, and performance profiling Video 🎥Swift’s Measurement API — From Miles to Meters and BeyondSwift’s Measurement API introduces a powerful way to perform unit conversions—like miles to kilometers or Celsius to Fahrenheit—without manual calculations. This video explains how to model values with Measurement, convert between units seamlessly, and leverage type-safe arithmetic for cleaner, more reliable code. A solid walkthrough for anyone enhancing apps with scientific or regional formatting. Two Practical Ways to Use matchedGeometryEffect() in SwiftUINatalia Panferova demonstrates two effective use cases for SwiftUI’s matchedGeometryEffect(), showcasing how to create seamless animations when views transition or change layout. This video is ideal for developers looking to elevate UI transitions with minimal code. Books 📚Alice’s Adventures in a Differentiable WonderlandThe author titled the work “Adventures of Alice in the Differentiable Wonderland”—a true fantasy journey through the world of neural networks and deep learning. Nearly 300 pages cover everything from basic math to the evolution of language models and transformers, blending theory, code examples, and playful storytelling to make complex topics accessible. Yet, another thing… 🧮CalcGPT.ioImagine a tools that fully relies on current mood, cloud-processing and LLM. Big analytical service or AI-agent? No, it’a calculator based on ChatGPT. Math will never be the same 😀 Thanks for reading Those Who Swift! Subscribe for free to receive new posts.
