Are you sure you are using variables and not constants?

1 Answer

Michiel Peters nailed it. I had the same problem and checked to see if I was using var's but I was still using constants "let's" from a previous time in the video. Long story short if your having this error most likely you are using constants instead of variables. Hope this helps someone having this problem! Keep swifting!
