Is he calling the constant a variable?

I noticed he called factBook a variable, even though it was declared as a constant using let. Even in the Xcode hints it has a V next to it for variable. Can constants be referred to as variables in a general sense, or am I missing something?

var is for variable and also means it could be change at anytime let for constant and you cannot change its value

// example

var x = 5 x= 6 println(x) // the new value is 6

let y = 7 y =8 // you can't do that because it a constant your compiler will complain

I had the same question. I understand the difference between a constant and a variable. The instructor refers to the factBook variable however the var keyword was never used in the code. I am still confused about this.
