It is the second objective in the first stage of the first course in the switft and IOS development track.

println("\(number) * 7 = \(number * 7)")
}
You interpolate the first variable, (number) then print out what the challenge requires you to say without a variable. "* 7 =". Then you interpolate the final answer as a variable. Just calculate the number and multiple it by 7. The for-in loop then increments the number value for each variation, giving you the 1-10 times table.
I might have made that sound really confusing..., let me know if you have any questions about it.
