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

what's the right answer to this 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.

how to assign the result to a constant named totalScore?

operators2.swift
// Enter your code below

var initialScore = 8

initialScore = ++initialScore
let totalScore = initialScore

For me it worked with just writing it in one line like here below... Try that :)

let totalScore = ++initialScore
