• xcrun simctl io booted recordVideo — type=mp4 ./test.mp4
• xcrun simctl io booted screenshot ./screen.png
• xcrun simctl addmedia booted ./test.mp4
• `xcrun simctl spawn booted log stream > test.log&`; open test.log;
• xcrun simctl terminate <pkg> (or terminate foreground app 🤞)

Some other ideas

• xcrun simctl appinfo booted <bundle-id>
• add simulator type and iOS version into screenshot/video filename
• add build - build and run iOS project
• add layout bounds enabled build
• enhance launch - add app chooser
• enhance uninstall - add app chooser
• and something from the following:

xcrun simctl <command>

	addmedia            Add photos, live photos, videos, or contacts to the library of a device.
