Taking First Steps into Metal Shaders
Learn the basics of Metal with SwiftUI to take your first steps on using shaders in your app UI
The article explains how Metal shaders work in SwiftUI and why GPU pixel-by-pixel rendering enables richer effects than normal view-based animations.
It shows how to create a .metal file with [[ stitchable ]] shader functions (solid color and a position-based gradient) and apply them to SwiftUI views via .colorEffect() using Xcode’s auto-generated ShaderLibrary.

Announcing Swift System Metrics 1.0: Process-Level Monitoring
Swift System Metrics 1.0 has been announced. It's a Swift package for process-level monitoring (CPU time, memory usage, file descriptors, start time) on Linux and macOS.
The article explains how it plugs into the Swift observability stack (Swift Metrics, Prometheus/OpenTelemetry backends, and Swift Service Lifecycle) and says the API is now stable for production.
The community is invited to contribute more metrics and platform support, and he commits to keeping changes backwards-compatible going forward.

Custom Parameters and Animation with Metal Shaders
Learn how to create and use parametrized shaders with Metal and SwiftUI
Letizia Granata explains how SwiftUI Metal shaders work per pixel, then shows how to pass custom parameters (via .float() and .color(), with strict parameter order) to build a configurable chessboard effect.
She also demonstrates time-based animation using TimelineView and sine waves to smoothly cycle RGB colors over time.

Age requirements for apps distributed in Brazil, Australia, Singapore, Utah, and Louisiana
• Declared Age Range API updated (beta): age category + age-assurance method signal; extra signals for regulatory requirements / required sharing / parent permission.
• Brazil: age category shared only with user or parent/guardian consent; loot boxes disclosure in the age-rating questionnaire can update the Brazil storefront rating to 18+.
• Australia/Brazil/Singapore: since Feb 24, 2026, 18+ apps are blocked unless the user is confirmed an adult (App Store handles this automatically).
• Utah/Louisiana: new Apple Accounts (UT May 6, 2026; LA July 1, 2026) can share age categories via the API; more tools added (PermissionKit, StoreKit age-rating property, Server Notifications, Significant Update Action beta).
