iOS -
Boot app with xcrun simctl bootstatus "iPhone 13 Pro" -b
This command either returns immediately when the simulator is already booted, or boots the simulator then returns.

The simulator is booted in the background, so run open /Applications/Xcode.app/Contents/Developer/Applications/Simulator.app to open the simulator app.
