Swift Array append()

var city = ["Boston", "Tokyo", "Kathmandu"]

// add "London" to the city array
city.append("London")

print(city)

// Output: [ "Boston", "Tokyo", "Kathmandu", "London" ]

append() Syntax

The syntax of the array append() method is:

array.append(newElement)

Here, array is an object of the Array class.

append() Parameters

The append() method takes a single parameter:

• newElement - element to be added to array

append() Return Value

The append() method doesn't return any value. It only updates the current array.

Example 1: Swift Array append()

var languages = ["Swift", "C", "Java"]

// add "C++" to the languages array
languages.append("C++")
print(languages)

var priceList = [12, 21, 35]

// add 44 to the priceList array
priceList.append(44)
print(priceList)

Output

["Swift", "C", "Java", "C++"]
[12, 21, 35, 44]

Example 2: Adding One Array To Another Array

//  animals array
var animals = ["cat", "dog"]

// array of wild animals
var wildAnimals = ["tiger", "fox"]

//  appending wildAnimals array to animals
animals.append(contentsOf: wildAnimals)

print(animals)

Output

["cat", "dog", "tiger", "fox"]

In the above example, we have used the append() method and contentsOf property to append the elements of wildAnmals to animals.
