## Overview
The **`split(separator:)` method** returns the longest possible sub-sequences of a collection. In this case, we want to use this method to split a string into an array of characters.

## Syntax
This is the syntax for the `split(separator:)` method:

```swift
string.split(separator: separatorElement)
```
## Parameters

**`separatorElement`**: This is the element that should be split upon.
## Return value

The `split` method returns smaller sub-parts of the array that are obtained from the subject string.

## Code example


// create some strings
let numbers = "1 2 3 4"
let alphabets = "a-b-c-d"

// split strings into characters
let numberCharacters = numbers.split(separator: " ")
let alphabetCharacters = alphabets.split(separator: "-")

// print results
print(numberCharacters)
print(alphabetCharacters)

## Code explanation

* **Lines 2–3**: We create two strings, `numbers` and `strings`.
* **Lines 6–7**: We split the strings into characters. 
* **Lines 10–11**: We print the results to the console.
