Initializers

init(base:separator:)

Creates an iterator that presents the elements of the sequences traversed by base, concatenated using separator.

Complexity: O(separator.count).

Declaration

  • init<Separator : Sequence where Separator.Iterator.Element == Base.Element.Iterator.Element>(base: Base, separator: Separator)

Instance Methods

mutating func next()

Advances to the next element and returns it, or nil if no next element exists.

Once nil has been returned, all subsequent calls return nil.

Declaration

  • mutating func next() -> Base.Element.Iterator.Element?
