How to output log to terminal from iOS simulator?

$

Logging to Chrome is extremely slow for me to the point of being unusable so I'm trying to get it to log to the terminal instead. They provide a command react-native log-ios for this but it gives me this error:

error Cannot read property 'udid' of null. Run CLI with --verbose flag for more details.

which, like 99% of React Native errors, makes no sense to me.

Any idea how I can get this command to work? Or is there any system command, similar to adb logcat for Android, that I can use directly to print iOS Simulator log to the terminal?
