# isEmpty A Boolean value indicating whether the collection is empty. ``` var isEmpty: Bool { get } ``` ## Discussion When you need to check whether your collection is empty, use the `isEmpty` property instead of checking that the `count` property is equal to zero. For collections that don’t conform to `RandomAccessCollection`, accessing the `count` property iterates through the elements of the collection. ``` let horseName = "Silver" if horseName.isEmpty { print("My horse has no name.") } else { print("Hi ho, \(horseName)!") } // Prints "Hi ho, Silver!") ``` > Complexity: O(1) --- Copyright © 2026 Apple Inc.
