Getting started
Xcode Simulator setup & testing
Install the runtime and test native apps across display, fold and orientation changes.
Design
Safe areas & layout margins
Use configuration-specific references, then distinguish window insets, margins and fold-reserved regions.
Design

Plan checks for layouts, state, input and hybrid behavior across device changes.
WebView
WKWebView, viewports & keyboards
Coordinate native and web layout, with a responsive fallback for opt-in Safari experiments and a Vue example.
