func index(after i: Dictionary<Key, Value>.Index) -> Dictionary<Key, Value>.Index
iA valid index of the collection. i must be less than end.
The index value immediately after i.
The successor of an index must be well defined. For an index i into a collection c, calling c returns the same index every time.
var startThe position of the first element in a nonempty dictionary.
var endThe dictionary’s “past the end” position—that is, the position one greater than the last valid subscript argument.
func formReplaces the given index with its successor.
func index(Dictionary<Key, Value>.Index, offsetReturns an index that is the specified distance from the given index.
func formOffsets the given index by the specified distance.
func index(Dictionary<Key, Value>.Index, offsetReturns an index that is the specified distance from the given index, unless that distance is beyond a given limiting index.
func formOffsets 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: DefaultThe indices that are valid for subscripting the collection, in ascending order.
