How do you get the multiple of something then add it to an array inside the body of a for in loop?

how is this not right?

var results: [Int] = [6]

for multiplier in 1...10 { print("(multiplier) times 5 is equal to (multiplier * 6)") results = results + (multiplier) }

loops.swift 
// Enter your code below
var results: [Int] = [6]

for multiplier in 1...10 {
    print("\(multiplier) times 5 is equal to \(multiplier * 6)")
 results = results + \(multiplier)
}

You have tried to use String Interpolation when adding an integer to an array.

  1. You don't need to interpolate multiplier when you aren't printing it in a string.
  2. To add a value to an array, use the .append() function.

results.append(multiplier) may be what you're looking for.
