# endIndex The array’s “past the end” position—that is, the position one greater than the last valid subscript argument. ``` var endIndex: Int { get } ``` ## Discussion 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`. --- Copyright © 2026 Apple Inc.
