Your code works great, but you are adding an additional line break \n, wich is not needed. println() already adds a line break, as opposed to print(). So this should pass

for number in 1...10 {
  println("\(number) * 7 = \(number*7)")
}

and this should work, too:

for number in 1...10 {
  print("\(number) * 7 = \(number*7)\n")
}
