These topics overlap with macOS development but live in separate suites:
axiom-macos vs axiom-swiftui: When working on a macOS SwiftUI app:
axiom-macos vs axiom-security: For sandbox and code signing:

iOS screen capture? ScreenCaptureKit is macOS-only. For iOS screen recording, use ReplayKit — see axiom-media.
