Hi Bandoro

You don't have an error it's just a warning and nothing to be alarmed about. Swift is basically saying use '' instead of let language. In simple terms when you code in Swift the use '' is a general token which indicates a variable exists but it is not being used. When you programme more and more in Swift you will come across this so it is worth while knowing what it is.

Hope that helps
