Record iOS Simulator Fish Function

simrecord.fish

function simrecord
    if count $argv > /dev/null
        set save_dir $argv
    else
        set save_dir ~/Downloads
    end

    pushd $save_dir
    xcrun simctl io booted recordVideo --mask black --codec "h264" SimulatorRecording-(date +%F)-(date +%H.%M.%S).mov
    popd
end

ctrl + c is the only way to stop the recording ?

yup!
