Import import Swift

Initializers

init(base:separator:)

Creates a sequence that presents the elements of base sequences concatenated using separator.

Complexity: O(separator.count).

Declaration

init<Separator>(base: Base.Iterator, 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() -> JoinedSequence<Base>.Iterator.Element?
