Instance Method

index(after:)

Returns the position immediately after the given index.

Required. Default implementation provided.

Declaration

override func index(after i: Self.Index) -> Self.Index

Parameters

i

A valid index of the collection. i must be less than endIndex.

Return Value

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.index(after: i) returns the same index every time.
