Nils,

What this For-In Loop is doing is taking our number and assigning it a number 1 through 10. Each time multiplying that number by 6 and printing it out. 

for number in 1...10{
    print("\(number) times 6 is equal to \(number * 6)")  // number * 6
}

1 times 6 is equal to 6 2 times 6 is equal to 12 3 times 6 is equal to 18 4 times 6 is equal to 24 5 times 6 is equal to 30 6 times 6 is equal to 36 7 times 6 is equal to 42 8 times 6 is equal to 48 9 times 6 is equal to 54 10 times 6 is equal to 60
