1,835 PointsQuestions about last code challenge, unsure of how to complete the task.
Can someone shed some light on why this was not correct for the last code challenge: 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.
My code:
var initialScore = 8
initialScore = initialScore + 1
var totalScore = initialScore

Treehouse TeacherYour code would have the same result as what the challenge is expecting. But the challenge explicitly asks for the increment operator ++. And as the challenge notes, the placement of this is key. Just because something is functional and has the same result outside of the challenge doesn't necessarily mean that it fulfills the challenge requirements. Hope that makes sense!

1,835 PointsThanks Jennifer, I see that this answer is accepted as well:
var initialScore = 8
let totalScore = ++initialScore
I know that future versions of swift '++' will be depreciated and removed in swift 3. Is that correct though?
Jennifer Nordell
Treehouse TeacherYes, it will be (and possibly is now) deprecated. You will be using let y += 1 for example

1,835 PointsOk, I think I got it! If you have any recommendations for future reading let me know. I appreciate all your help!

1,835 PointsThank you so much for your response Jennifer! I was able to figure it out with your hints. Thank you thank you!
var initialScore = 8
let totalScore = initialScore
initialScore = ++initialScore

Treehouse TeacherYou're sooooooo close here. And in fact, you're so close I'm just going to give another hint. Your code should only be two lines long. The beginning declaration of initialScore and the beginning declaration of totalScore which should have the properly incremented initalScore assigned to it. Try and get what you have there in two lines of code
