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

What's wrong with this? var initialScore = 8 var totalScore = ++initialScore


// Enter your code below

var initialScore = 8
var totalScore = ++initialScore

1 Answer

Swift 3 does not support the '++' operator. Instead, you have to use '+=' and format your code to accommodate that operator.

I think you could change yours to:

var initialScore = 8
var totalScore = initialScore
totalScore += 1
