# Installs the app in a new iPhone simulator and runs the scripted UI cases with the ui helper: onboarding to the
# chat list with the one-hand UI (the default), then the chat list again with the top bar. It leaves the app in the one-hand UI.
# Usage: scripts/ci/ios-sim/smoke-test.sh <path to SimpleX.app> <output dir>
# Each step saves a screenshot and an accessibility tree to the output dir and prints the tree to the log.
# Later steps of the job get SIM_UDID and UI_OUT, with the simulator still running.
