"++" are removed from swift 3, got this message in xcode.

This is giving error in swift 3: let totalScore = ++initialScore

so is this the right way: let totalScore = initialScore + 1

operators2.swift 
// Enter your code below

var initialScore = 8
let totalScore = ++initialScore

You are partially correct - if you write 

let totalScore = initialScore + 1

you will correctly make totalScore 9 (in the example), but you're not doing the other part of the old ++initialScore which is that ++ also increments the variable, making initialScore = 9 as well. So the fastest way of doing this would be something like this: 

var initialScore = 8
initialScore += 1 //This is the short way of saying: initialScore = initialScore + 1
let totalScore = initialScore

That would increment initialScore, and then assign that value (9) to the constant totalScore.
