# removingSubranges(_:) Returns a collection of the elements in this collection that are not represented by the given range set. ``` func removingSubranges(_ subranges: RangeSet) -> DiscontiguousSlice ``` ## Parameters `subranges` A range set representing the indices of the elements to remove. ## Return Value A collection of the elements that are not in `subranges`. ## Discussion For example, this code sample finds the indices of all the vowel characters in the string, and then retrieves a collection that omits those characters. ``` let str = "The rain in Spain stays mainly in the plain." let vowels: Set = ["a", "e", "i", "o", "u"] let vowelIndices = str.indices(where: { vowels.contains($0) }) let disemvoweled = str.removingSubranges(vowelIndices) print(String(disemvoweled)) // Prints "Th rn n Spn stys mnly n th pln." ``` > Complexity: O(*n*), where *n* is the length of the collection. --- Copyright © 2026 Apple Inc.
