swift for문 index알기

Yes. As of Swift 2.0, if you need the index for each element along with its value, you can use the enumerate() method to iterate over the array. It returns a tuple composed of the index and the value for each item in the array. For example:

for (index, element) in list.enumerate() {
    print("Item \(index): \(element)")
}

Prior to Swift 2.0, enumerate was a global function.

for (index, element) in enumerate(list) {
    println("Item \(index): \(element)")
}
