var startIndex: String.Index

The position of the first character in a nonempty string.

var endIndex: String.Index

A string’s “past the end” position—that is, the position one greater than the last valid subscript argument.

func formIndex(after: inout String.Index)

Replaces the given index with its successor.

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

Returns the position immediately before the given index.

func formIndex(before: inout String.Index)

Replaces the given index with its predecessor.

func index(String.Index, offsetBy: String.IndexDistance) -> String.Index

Returns an index that is the specified distance from the given index.

func index(String.Index, offsetBy: String.IndexDistance, limitedBy: String.Index) -> String.Index?

Returns an index that is the specified distance from the given index, unless that distance is beyond a given limiting index.

func formIndex(inout String.Index, offsetBy: Int)

Offsets the given index by the specified distance.

func formIndex(inout String.Index, offsetBy: Int, limitedBy: String.Index) -> Bool

Offsets the given index by the specified distance, or so that it equals the given limiting index.

func distance(from: String.Index, to: String.Index) -> String.IndexDistance

Returns the distance between two indices.

var indices: DefaultIndices<String>
