Manipulating Indices
var startIndex : Dictionary<Key, Value>.IndexThe position of the first element in a nonempty dictionary.
var endIndex : Dictionary<Key, Value>.IndexThe dictionary’s “past the end” position—that is, the position one greater than the last valid subscript argument.
func index(after: Dictionary<Key, Value>.Index) -> Dictionary<Key, Value>.IndexReturns the position immediately after the given index.
func index(Dictionary<Key, Value>.Index, offsetBy : Int) -> Dictionary<Key, Value>.IndexReturns an index that is the specified distance from the given index.
func formIndex (inout Dictionary<Key, Value>.Index, offsetBy : Int)Offsets the given index by the specified distance.
func index(Dictionary<Key, Value>.Index, offsetBy : Int, limitedBy : Dictionary<Key, Value>.Index) -> Dictionary<Key, Value>.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 Dictionary<Key, Value>.Index, offsetBy : Int, limitedBy : Dictionary<Key, Value>.Index) -> BoolOffsets the given index by the specified distance, or so that it equals the given limiting index.
func distance(from: Dictionary<Key, Value>.Index, to: Dictionary<Key, Value>.Index) -> IntReturns the distance between two indices.
var indices: DefaultIndices<Dictionary<Key, Value>> The indices that are valid for subscripting the collection, in ascending order.
