We are learn Swift in hard way here...

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.

Need help i can see my mistake....

loops.swift
// Enter your code below
var results: [Int] = []
for i in 1...10 {
let multiplier = 6 * 1
results.append(multiplier)
}
for multiplier in 1...10 {
results.append(multiplier * 6)
}
let multiplier = 6 * 1
results.append(multiplier)

Hi Ary,

The first thing they want you to do in this challenge is to create a for-in loop going from 1 to 10 like this:

for temp in 1...10 {  }

In a for-in loop you must name a temporary value, and in the above example that value is named temp. For this challenge they want you to name it multiplier:

for multiplier in 1...10 {  }   // changed temp to multiplier

The second part of the challenge is to create the multiples of 6. So

  • 6*1
  • 6*2
  • 6*3
  • and so on

remember that conveniently the multiplier is also going through 1 to 10. So you can replace the right numbers with

for multiplier in 1...10 {  
   let value = 6 * multiplier
}

for each iteration of the loop, you'll be getting a multiple of 6. The challenge wants you to store this value inside the result array:

for multiplier in 1...10 {  
   let multiple = 6 * multiplier
   results.append(multiple)   // storing the value in the results array.
}

Good luck! :)

I'm not able to complete this excercise too, he says me that there is "Bummer! Your array needs to contain the first 10 multiples. Make sure your range goes from 1 to 10"

I wrote this code that was build on the previus step

var results: [Int] = [6]

for multiplier in 1...10{

print (\(multiplier * 6))

}

Can someone plese help me fixing my mistake please?
