How to loop through items in an array
Swift version: 5.10
Swift offers a selection of ways to loop through an array, but the easiest and fastest is known as fast enumeration and looks like this:
let array = ["Apples", "Peaches", "Plums"]
for item in array {
print("Found \(item)")
}That will print "Found Apples", "Found Peaches" then "Found Plums" to the Xcode console. Each time the loop goes around, one item is read from the array and placed into the constant item – and note that is a constant, so don't try to change it.
