max(count:)
Returns the largest elements of this collection.
func max(count: Int) -> [Element] Parameters
- count
The number of elements to return. If
countis greater than the number of elements in this collection, all of the collection’s elements are returned.
Returns
An array of the largest count elements of this collection.
This example partially sorts an array of integers to retrieve its three largest values:
let numbers = [7, 1, 6, 2, 8, 3, 9]
let smallestThree = numbers.max(count: 3)
// [7, 8, 9]If you need to sort a collection but only need to access its largest elements, using this method can give you a performance boost over sorting the entire collection. The order of equal elements is guaranteed to be preserved.
