Instance Property


The last element of the collection.


var last: Bound? { get }
Available when Bound conforms to Strideable and Bound.Stride conforms to SignedInteger.


If the collection is empty, the value of this property is nil.

let numbers = [10, 20, 30, 40, 50]
if let lastNumber = numbers.last {
// Prints "50"

Complexity: O(1)
