Iterator
An iterator that presents the elements of the sequences traversed by a base iterator, concatenated using a given separator.
@frozen struct IteratorAn iterator that presents the elements of the sequences traversed by a base iterator, concatenated using a given separator.
@frozen struct Iteratorimport Swift@frozen struct JoinedSequence<Base> where Base : Sequence, Base.Element : SequenceA sequence that presents the elements of a base sequence of sequences concatenated using a given separator.
protocol Sequence<Element>A type that provides sequential, iterated access to its elements.
func makeIterator() -> JoinedSequence<Base>.Iterator Return an iterator over the elements of this sequence.
protocol CopyableA type whose values can be implicitly or explicitly copied.
protocol Escapableprotocol IteratorProtocol<Element>A type that supplies the values of a sequence one at a time.
init<Separator>(base: Base.Iterator, separator: Separator) where Separator : Sequence, Separator.Element == Base.Element.Element Creates an iterator that presents the elements of base sequences concatenated using separator.
mutating func next() -> JoinedSequence<Base>.Iterator.Element? Advances to the next element and returns it, or nil if no next element exists.
