How do I complete the for-in loop challenge for Swift?

Here's the question: Use a for-in loop to print out a "7 times table". Your output should look like this: 1 * 7 = 7 2 * 7 = 14 Etc., all the way up to 10. Each line should be on a new line.

Here's my code:

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

What am I doing wrong? It complies as expected in my playground.

remove the new line character from the end. since you are using the println function everything will be on a separate line regardless.

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