The position of the first element in a nonempty collection.
var startIndex: Repeated<Element>.Index { get }In a Repeated collection, startIndex is always equal to zero. If the collection is empty, startIndex is equal to endIndex.
import Swift@frozen struct Repeated<Element>A collection whose elements are all identical.
typealias Index = IntA type that represents a valid position in the collection.
let count: IntThe number of elements in this collection.
var endIndex: Repeated<Element>.Index { get }The collection’s “past the end” position—that is, the position one greater than the last valid subscript argument.
let repeatedValue: ElementThe value of every element in this collection.
subscript(position: Int) -> Element { get } Accesses the element at the specified position.
typealias Indices = Range<Int>
