/**
 * Info.plist key read by expo's native runtime (`ExpoReactNativeFactory`) to resolve the Metro
 * dev server port at launch. It is set to the `RCT_METRO_PORT` build setting so that
 * `expo run:ios --port <n>` flows through to the app.
 *
 * Prebuilt React freezes the compile-time `RCT_METRO_PORT` at `8081`, so without this a bare dev
 * build (no `expo-dev-client`) always defaults to `:8081` and multiple running projects collide on
 * a single dev server. This is the iOS analog of Android's `react_native_dev_server_port` resource.
