Iterator

import Swift

@frozen struct UnicodeScalarView

A view of a string’s contents as a collection of Unicode scalar values.

@frozen struct String

A Unicode string value that is a collection of characters.

init()

Creates an empty view instance.

var customMirror: Mirror { get }

Returns a mirror that reflects the Unicode scalars view of a string.

var debugDescription: String { get }

var description: String { get }

var endIndex: String.UnicodeScalarView.Index { get }

The “past the end” position—that is, the position one greater than the last valid subscript argument.

var startIndex: String.UnicodeScalarView.Index { get }

The position of the first Unicode scalar value if the string is nonempty.

subscript(r: Range<String.UnicodeScalarView.Index>) -> String.UnicodeScalarView.SubSequence { get }

subscript(position: String.UnicodeScalarView.Index) -> Unicode.Scalar { get }

Accesses the Unicode scalar value at the given position.

mutating func append(_ c: Unicode.Scalar)

Appends the given Unicode scalar to the view.

mutating func append<S>(contentsOf newElements: S) where S : Sequence, S.Element == Unicode.Scalar

Appends the Unicode scalar values in the given sequence to the view.

func distance(from start: String.UnicodeScalarView.Index, to end: String.UnicodeScalarView.Index) -> Int

func index(_ i: String.UnicodeScalarView.Index, offsetBy distance: Int) -> String.UnicodeScalarView.Index

func index(_ i: String.UnicodeScalarView.Index, offsetBy distance: Int, limitedBy limit: String.UnicodeScalarView.Index) -> String.UnicodeScalarView.Index?

func index(after i: String.UnicodeScalarView.Index) -> String.UnicodeScalarView.Index

Returns the next consecutive location after i.

func index(before i: String.UnicodeScalarView.Index) -> String.UnicodeScalarView.Index

Returns the previous consecutive location before i.

func makeIterator() -> String.UnicodeScalarView.Iterator

mutating func replaceSubrange<C>(_ subrange: Range<String.UnicodeScalarView.Index>, with newElements: C) where C : Collection, C.Element == Unicode.Scalar

Replaces the elements within the specified bounds with the given Unicode scalar values.

mutating func reserveCapacity(_ n: Int)

Reserves enough space in the view’s underlying storage to store the specified number of ASCII characters.

typealias Index = String.Index

typealias SubSequence = Substring.UnicodeScalarView

var customPlaygroundQuickLook: _PlaygroundQuickLook { get }

protocol IteratorProtocol<Element>

A type that supplies the values of a sequence one at a time.

protocol Sendable

mutating func next() -> Unicode.Scalar?
