Help me debug my code

var results: [Int] = [] let multiplier = for x in 1...10{x*6} results.append(multiplier)

In iterating over the array, what is wrong with my code? Thanks

Your code:

var results: [Int] = [] 

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

Get rid of let. In a for in loop, the constant multiplier goes between the for and the in. Don't need the x since multiplier is the name used for every item when iterating through the array. Also, results.append() goes inside the for in loop.

My suggestion:

var results: [Int] = []

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