## Overview
The **`append()` method** adds single or multiple elements to an array in Swift. It is invoked by an array. We use `append(_:)` to add a single element. Alternatively, we use `append(contentsOf:)` if we want to add a multiple.

## Syntax


// single element
arr.append(element)
// multiple element
arr.append(contentsOf: [element1, element2...])


## Parameters

**`element`**: This is the single element we want to append to the `arr` array.

**`[element1, element2,...]`**: This is an array of elements we want to append to the `arr` array.

## Return value

A new array with newly appended elements is returned.

## Code example


// create an array
var languages = ["Java", "C++", "Python"]

// append a single element
languages.append("Perl")

// append multiple elements
languages.append(contentsOf: ["Ruby", "Swift"])

// print array values
for lang in languages{
  print(lang)
}

## Explanation

* **Line 2**: We create an array called `languages`.
* **Line 5**: We append a single element to the array.
* **Line 8**: Two elements are appended to our array.
* **Line 11**: The `for-in` loop prints each element of the array.
