# init(_:) Creates a new string containing the characters in the given sequence. ``` init(_ other: S) where S : LosslessStringConvertible, S : Sequence, S.Element == Character ``` ## Parameters `other` A string instance or another sequence of characters. ## Discussion You can use this initializer to create a new string from the result of one or more collection operations on a string’s characters. For example: ``` let str = "The rain in Spain stays mainly in the plain." let vowels: Set = ["a", "e", "i", "o", "u"] let disemvoweled = String(str.lazy.filter { !vowels.contains($0) }) print(disemvoweled) // Prints "Th rn n Spn stys mnly n th pln." ``` --- Copyright © 2026 Apple Inc.
