@frozen struct StringA 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.
