Hi,

I’m getting this error in the console when trying to replicate the Filter exercise.

Value of type ‘String.Element’ (aka ‘Character’) has no member ‘count’.

My code is:

let moreThanFour = names.filter { $0.count > 4 }
print(moreThanFour)

To me seems that all looks good. My Xcode version is 14.1.

Any suggestions?

Thank you,
Elvis

Solved. I wrote .reduce at the end of the main names array and that’s why it was throwing the error.
