      "--simulator <value>: iOS simulator name or UDID to install and run the build on; if omitted, the CLI prompts for a simulator.",
      "--platform <ios|android>: Selects the platform; use `ios` for this task.",
      "eas build:run build selector (`--latest`, `--id`, `--path`, or `--url`) (required): Selects the simulator/emulator build to run. The documented syntax presents these as alternatives.",
      "eas build:dev --profile: Selects a build profile; it must allow emulator/simulator internal-distribution development builds. Defaults to `development-simulator`.",
      "Prerequisite: For `build:dev`, use a build profile that allows emulator/simulator internal-distribution development builds; `development-simulator` is the default."
