# drop(while:) Returns a subsequence by skipping elements while `predicate` returns `true` and returning the remaining elements. ``` func drop(while predicate: (Self.Element) throws -> Bool) rethrows -> Self.SubSequence ``` ## Parameters `predicate` A closure that takes an element of the sequence as its argument and returns `true` if the element should be skipped or `false` if it should be included. Once the predicate returns `false` it will not be called again. ## Discussion> Complexity: O(*n*), where *n* is the length of the collection. --- Copyright © 2026 Apple Inc.
