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

for in loop

I was asked to create a loop of numbers from 1 to 10, multiply the numbers by 6 in the body of the loop and then append the result in an array so that the array will contain the the results for the first ten multiples of 6. So I did this but it's obvious my code is not correct. Please help.

loops.swift 
// Enter your code below
for multiplier in 1...10 {
    let b = 6 * multiplier
    var array = []
    array += [b] 
}

Hi. You do not need to create a constant to multiply the range by 6. Here is what i did:

var results: [Int] = []

for multiplier in 1...10 {
    results.append(multiplier * 6)
}

Also the array should've already been created for you, so there is no need to make another one. It is much easier and more efficient to do the above, rather than what you did

 let b = 6 * multiplier

and then appending it to an array inside the loop.

Anyway, I hope that was clear. Good Luck :)
