letters
Returns a character set containing the characters in Unicode General Category L* & M*.
static var letters: CharacterSet { get }Returns a character set containing the characters in Unicode General Category L* & M*.
static var letters: CharacterSet { get }import Foundationstruct CharacterSetA CharacterSet represents a set of Unicode-compliant characters. Foundation types use CharacterSet to group characters together for searching operations, so that they can find any of a particular set of characters during a search.
init() Initialize an empty instance.
init(bitmapRepresentation data: Data) Initialize with a bitmap representation.
init(charactersIn range: ClosedRange<UnicodeScalar>) Initialize with a closed range of integers.
init(charactersIn string: String) Initialize with the characters in the given string.
init(charactersIn range: Range<UnicodeScalar>) Initialize with a range of integers.
init?(contentsOfFile file: String) Initialize with the contents of a file.
init(from decoder: any Decoder) throws static var alphanumerics: CharacterSet { get }Returns a character set containing the characters in Unicode General Categories L*, M*, and N*.

static var newlines: CharacterSet { get }Returns a character set containing the newline characters (U+000A ~ U+000D, U+0085, U+2028, and U+2029).
static var nonBaseCharacters: CharacterSet { get }Returns a character set containing the characters in Unicode General Category M*.
static var punctuationCharacters: CharacterSet { get }Returns a character set containing the characters in Unicode General Category P*.

static var uppercaseLetters: CharacterSet { get }Returns a character set containing the characters in Unicode General Category Lu and Lt.
static var urlFragmentAllowed: CharacterSet { get }Returns the character set for characters allowed in a fragment URL component.
static var urlHostAllowed: CharacterSet { get }Returns the character set for characters allowed in a host URL subcomponent.
static var urlPasswordAllowed: CharacterSet { get }Returns the character set for characters allowed in a password URL subcomponent.
static var urlPathAllowed: CharacterSet { get }Returns the character set for characters allowed in a path URL component.
static var urlQueryAllowed: CharacterSet { get }Returns the character set for characters allowed in a query URL component.
static var urlUserAllowed: CharacterSet { get }Returns the character set for characters allowed in a user URL subcomponent.
static var whitespaces: CharacterSet { get }Returns a character set containing the characters in Unicode General Category Zs and CHARACTER TABULATION (U+0009).
static var whitespacesAndNewlines: CharacterSet { get }Returns a character set containing characters in Unicode General Category Z*, U+000A ~ U+000D, and U+0085.
var bitmapRepresentation: Data { get }Returns a representation of the CharacterSet in binary format.
var debugDescription: String { get }var description: String { get }var inverted: CharacterSet { get }Returns an inverted copy of the receiver.

func contains(_ member: UnicodeScalar) -> Bool Test for membership of a particular UnicodeScalar in the CharacterSet.
func encode(to encoder: any Encoder) throws mutating func formIntersection(_ other: CharacterSet) Sets the value to an intersection of the CharacterSet with another CharacterSet.
mutating func formSymmetricDifference(_ other: CharacterSet) Sets the value to an exclusive or of the CharacterSet with another CharacterSet.
mutating func formUnion(_ other: CharacterSet) Sets the value to a union of the CharacterSet with another CharacterSet.
