How to create constant?

I have tried to create a constant as I saw in this session but I could't do it I don't know how!

var str = "Hello, bestSmartphone"
var someVariable = "aVariable"
let someConstant = bestSmartphone

Hi there! You've created at least one constant and set it equal to a variable named bestSmartphone which doesn't exist anywhere else in your code. The first step is only looking for one line of code and the constant name is supposed to be bestSmartphone with a value of "iPhone". Take a look:

let bestSmartphone = "iPhone"

This creates a constant named bestSmartphone and assigns the string "iPhone" to that constant. Hope this helps! :sparkles:

I've actually entered that answer but I don't know why I keep getting a "Bummer! Your code could not be compiled. Please click on "Preview" to view the compiler errors." error.
