Is there a function that I can use to iterate over an array and have both index and element, like Python’s enumerate
?
for index, element in enumerate(list):
...
17 s
Yes. As of Swift 3.0, if you need the index for each element along with its value, you can use the enumerated()
method to iterate over the array. It returns a sequence of pairs composed of the index and the value for each item in the array. For example:
for (index, element) in list.enumerated() {
print("Item \(index): \(element)")
}
Before Swift 3.0 and after Swift 2.0, the function was called enumerate()
:
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)")
}
