Iterating over multiple arrays in Swift

Question

I'm looking to basically match up two different arrays in Swift using the enumerated method. So if I have:

let array1 = ["a", "b", "c", "d"]
let array2 = ["1", "2", "3", "4"]

I need to return a new array that would read:

newArray = ["1. a1", "2. b2", "3. c3", "4. d4"]

How do I make an array like that?

Answer 1

I managed to figure it out with some help from a friend:

var newArray: [String] = []
    for (index, array1) in array1.enumerated() {
        newArray.append("\(index + 1). \(array1)(\(array2[index]))")
    }
    return newArray

Thanks!
