var customPlaygroundQuickLook: _PlaygroundQuickLook { get }import Swift@frozen struct SubstringA slice of a string.
init() Creates an empty substring.
init(_ content: Substring.UnicodeScalarView) Creates a Substring having the given content.
init(_ content: Substring.UTF8View) Creates a Substring having the given content.
init(_ content: Substring.UTF16View) Creates a Substring having the given content.

init(stringLiteral value: String) init(unicodeScalarLiteral value: String) var base: String { get }Returns the underlying string from which this substring was derived.
var customMirror: Mirror { get }var debugDescription: String { get }var description: String { get }var endIndex: Substring.Index { get }var isContiguousUTF8: Bool { get }Returns whether this string is capable of providing access to validly-encoded UTF-8 contents in contiguous memory in O(1) time.

If this substring is not contiguous, this will first make it contiguous, which will also speed up subsequent access. If this mutates the substring, it will invalidate any pre-existing indices.

mutating func withMutableCharacters<R>(_ body: (inout Substring) -> R) -> R Applies the given closure to a mutable view of the string’s characters.
typealias CharacterView = SubstringA view of a string’s contents as a collection of characters.
