protocol Collection<Element> : SequenceA sequence whose elements can be traversed multiple times, nondestructively, and accessed by an indexed subscript.
struct JoinedByCollection<Base, Separator> where Base : Collection, Separator : Collection, Base.Element : Collection, Separator.Element == Base.Element.ElementA collection that presents the elements of a base collection of collections concatenated using a given separator.
associatedtype Element where Self.Element == Self.Iterator.ElementA type representing the sequence’s elements.
func joined<Separator>(by separator: Separator) -> JoinedBySequence<Self, Separator> where Separator : Collection, Separator.Element == Self.Element.Element Returns the concatenation of the elements in this sequence of sequences, inserting the given separator between each sequence.
func joined<Separator>(by separator: (Element, Element) throws -> Separator) rethrows -> [Element.Element] where Separator : Sequence, Separator.Element == Self.Element.Element Returns the concatenation of the elements in this sequence of sequences, inserting the separator produced by the closure between each sequence.
func joined<Separator>(by separator: @escaping (Element, Element) -> Separator) -> JoinedByClosureCollection<Elements, Separator> where Separator : Collection, Separator.Element == Self.Element.Element Returns the concatenation of the elements in this collection of collections, inserting the separator produced by the closure between each sequence.
