let is an obsolete command for performing arithmetic. You want a command substitution. Then you need to use a specific command to perform the comparison; you can use either test or [[ ... ]]

current=$(git branch --show-current)

if [ "$current" = dev ]; then
    echo "On dev branch"
fi

if [[ $current = dev ]]; then
    echo "On dev branch"
fi
