endIndex
The array’s “past the end” position—that is, the position one greater than the last valid subscript argument.
var endIndex: Int { get }
Overview
When you need a range that includes the last element of an array, use the half-open range operator (..<
) with endIndex
. The ..<
operator creates a range that doesn’t include the upper bound, so it’s always safe to use with endIndex
. For example:
let numbers = [10, 20, 30, 40, 50]
if let i = numbers.firstIndex(of: 30) {
print(numbers[i ..< numbers.endIndex])
}
// Prints "[30, 40, 50]"
If the array is empty, endIndex
is equal to startIndex
.
