var count: Int { get }The number of elements.
var endIndex: AnyCollection<Element>.Index { get }The collection’s “past the end” position—that is, the position one greater than the last valid subscript argument.
var startIndex: AnyCollection<Element>.Index { get }The position of the first element in a non-empty collection.
var underestimatedCount: Int { get }subscript(bounds: Range<AnyCollection<Element>.Index>) -> AnyCollection<Element>.SubSequence { get } subscript(position: AnyCollection<Element>.Index) -> Element { get } Accesses the element indicated by position.
