# split(maxSplits:omittingEmptySubsequences:separator:) Returns the longest possible subsequences of the collection, in order, around subsequence that match the regex created by the given closure. ``` func split(maxSplits: Int = Int.max, omittingEmptySubsequences: Bool = true, @RegexComponentBuilder separator: () -> some RegexComponent) -> [Self.SubSequence] ``` ## Parameters `maxSplits` The maximum number of times to split the collection, or one less than the number of subsequences to return. `omittingEmptySubsequences` If `false`, an empty subsequence is returned in the result for each consecutive pair of matches and for each match at the start or end of the collection. If `true`, only nonempty subsequences are returned. `separator` A closure that returns a regex to be split upon. ## Return Value A collection of substrings, split from this collection’s elements. --- Copyright © 2026 Apple Inc.
