32,867 PointsHi Yanni,
nil can be a little tricky in Ruby. An empty string: "".nil? will return false. In this case you would want .empty? instead. Not sure if that has been covered or not yet in this course, and might be a little confusing since you are defining a method named empty?. The long way around would be:
def empty?
if @todo_items = []
return true
else
return false
end
end
