iOS Swift 2.0 Basics Swift Operators Working With Operators: Part 2

Would be glad if someone could help me with this..

Here is the task:

Let's assume we're creating a silly game. In this game every time a user completes an objective (whatever it is) we increment their total score by 1 point.

In the editor below, initialScore is the players current score. Assuming they completed a single objective for this level, let's add 1 point to their score using the increment operator and assign the result to a constant named totalScore.

Remember that the position of the unary increment operator matters. For this task to pass, we want both totalScore and initialScore to have the same value after the increment operation.

operators2.swift
// Enter
your code below

var initialScore = 8
let totalScore = ++initialScore

It worked for me. Just make sure the comment doesn't get changed or you will get an error:

The code should look like this:

// Enter your code below

var initialScore = 8
let totalScore = ++initialScore

Not this:

// Enter
your code below

var initialScore = 8
let totalScore = ++initialScore

This should work:

var initialScore = 8

let initialScore = ++totalScore

If not let me know! Thanks!
