Not sure where your stuck without seeing the code. But here is a simple example of a for loop in Swift

//Array which is a list of numbers var numbers = [1,2,3,4,5];

for number in numbers {

print(number);

}

//Prints 1,2,3,4,5 etc

Here you have a variable 'number' which is assigned a value from the numbers array which is then printed to the console. You can also do it in a short cut by creating a range like so

for number in 1...10 {

print(number)

}

Does the same thing- just a shorter way of doing it.

Ok this is tested in Swift 2.0 playground

for i in 1...10 {

let x = "\(i) * 7 = \(i * 7)";

print("\(x)\n")

}

//Logs 1 * 7 = 7

2 * 7 = 14

3 * 7 = 21

4 * 7 = 28

5 * 7 = 35

6 * 7 = 42

7 * 7 = 49

8 * 7 = 56

9 * 7 = 63

10 * 7 = 70

This works for the latest version of Swift!

Let's say you want 6 times table from 1 to 10 , for number in 1...10{ println("(number) times 6 is (number*6)") } the (number) prints from 1 to 10 and (number*6) multiplies 1 to 10 with 6, Good luck I think you got this
