## Overview

This example uses the `last(where:)`

method to find the last negative number in an array of integers:

```
let numbers = [3, 7, 4, -2, 9, -6, 10, 1]
if let lastNegative = numbers.last(where: { $0 < 0 }) {
print("The last negative number is \(lastNegative).")
}
// Prints "The last negative number is -6."
```
