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

What am I doing wrong... [SWIFT]

Challenge 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."

I've tried it other ways also... it still won't work. Can someone please tell me where I went wrong here? It said to assign the result, I assumed that meant either assigning it as an Integer or just reassigning the variable.

Hello Ryan. i just looked at your code and i can see where you went wrong. Bellow is what it should look like. What the second line code is actually doing is. it declares the total Score constant and assign it to the incremented variable initial Score. the increment is placed before the variable rather than after the variable. that is to add 1 to initial Score before it gets assigned to the totalScore constant. i hope this helps.

var initialScore = 8

let totalScore = ++initialScore
