func index(after: String.Index) -> String.Index
Returns the position immediately after the given index.
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>
