Build iPhone/iOS apps — native SwiftUI or Kotlin-Multiplatform hybrid. Use when user says "build an iOS app", "add a SwiftUI screen", "run it on my iPhone", "set up the Xcode project", or when scaffolding an iOS app, writing SwiftUI/ARKit/MapLibre features, wiring the Claude Code ↔ Xcode workflow, building or installing on a physical device, or setting up a project so it survives its first App Store upload (product name, orientations, encryption, dSYM, xcodeproj tracking). For TestFlight, submission, screenshots and store metadata use solo-ios-release instead.
