If I run the initial code even before adding to it, it gives out warning:

(test):10: warning: found = in conditional, should be ==

Not the best of instructions for this exercise; in fact they were a bit misleading. In step 3, instead of saying:

  1. For each s in strings , use .to_sym to convert s to a symbol and use .push to add that new symbol to symbols .

They should’ve said for each ‘s’ push it to symbols and then convert each string to symbol using .to_sym

I was getting the same error as you.
