Hi Lucas,

The key here is that they want both totalScore and initialScore to have the same value after the increment operation. To do this you place the increment operator before the constant totalScore.

var initialScore = 8

let totalScore = ++initialScore

let totalScore = ++initialScore let isWinner =

The wording on this challenge is somewhat confusing to a lot of people. What the challenge is asking you to do is to create a constant named isWinner and assign the value of (NOT equal to 10) 

var initialScore = 8

let totalScore = ++initialScore

var isWinner = (totalScore != 10)

Hi Im now at the swift course collections and control flow. and than this challenge:

Challenge Task 2 of 2

Inside the body of the loop, we're going to use the multiplier to get the multiple of 6. For example, if the multiplier is 1, then the multiple is 1 times 6, which is equal to 6.

Once you have a value, append it to the results array. This way once the for loop has iterated over the entire range, the array will contain the first 10 multiples of 6.

But i cant press the help button anymore...

This is my code:

// Enter your code below var results: [Int] = []

for multiplier in 1...10 { print("(multiplier) times 5 is equel to (multiplier * 5)") }

but i don't know what to do now, can you help me?
