Thanks Claude - that's exactly what happened. yes my code complies now but I have a new set of problems, which I'm going to try tackle myself over the next week. I will take your advice on how to manage and learn how to approach these. Of course, I'll mark the answer correct now and you too, have a nice day! Appreciate your help ALOT!

Thanks Claude, you've been a great help. I can sorta see how this works now with my very limited knowledge. I did have code after var TextFieldsStrings = (I think [string() though but it wouldn't let me send the code in here. (domain error) May I ask how you learnt swift? and if you have any advice?

Hey, thanks for the help! I've been trying to work this one out for a few days still. So do I need to delete the error here part and replace with the unwrapped line of code? I'm a little confused still. I tried declaring the newText as a variable it got rid of the editor placeholder in source file error but I was met with plenty more. Sorry if this is very basic. Appreciate the help!
