iOS Simulator (xcrun simctl)

Command-line control of the iOS/iPadOS/watchOS/tvOS Simulator for scripting, CI, and local fixtures. Everything routes through simctl; the Simulator.app GUI is optional. Targets Xcode 16/17, iOS 26 era.

• Device counterpart: hardware-backed features (camera, Secure Enclave, App Attest) do not work in the Simulator — see Simulator vs. real device and cross-reference device-integrity / swift-security.
• UI-test driving (tap/type/assert) is XCUITest's job, not simctl — see ios-testing. simctl sets up state around the test (permissions, push, media, location).
