How to enumerate items in an array

Swift version: 5.1

Paul Hudson    @twostraws   

There several ways to loop through an array in Swift, but using the enumerated() method is one of my favorites because it iterates over each of the items while also telling you the items's position in the array.

Here's an example:

let array = ["Apples", "Peaches", "Plums"]

for (index, item) in array.enumerated() {
    print("Found \(item) at position \(index)")
}

That will print "Found Apples at position 0", "Found Peaches at position 1", and "Found Plums at position 2".
