iOS Swift Collections and Control Flow Control Flow With Loops For In Loops

Swift Collections and Control Flow

  1. 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.

I am having trouble with his question I am not sure if i am appending the multiplier correctly.

// Enter your code below
var results: [Int] = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
for multiplier in results{
results.append(multiplier * 6)

First, there is no need to change the results variable to assign the numbers 1-10 as an array, keep it empty ([]).

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

for multiplier in 1 ... 10 {

    results.append(multiplier * 6)


thank you so much this makes a lot more sense.
