How to Shuffle an Array in Swift ?

Answer

In Swift, you can shuffle an array using the Fisher-Yates shuffle algorithm.

✐ Examples

1 Shuffle Array of Integers

In this example,

We have an array named intArray containing integers.
We apply the Fisher-Yates shuffle algorithm to intArray.
We print the shuffled array to demonstrate the shuffling.

Swift Program

import Foundation

var intArray = [1, 2, 3, 4, 5]
intArray.shuffle()
print("Shuffled Array:", intArray)

Output

Shuffled Array: [3, 5, 2, 4, 1]

2 Shuffle Array of Strings

In this example,

We have an array named strArray containing strings.
We apply the Fisher-Yates shuffle algorithm to strArray.
We print the shuffled array to demonstrate the shuffling.

Swift Program

import Foundation

var strArray = ["apple", "banana", "cherry"]
strArray.shuffle()
print("Shuffled Array:", strArray)

Output

Shuffled Array: [cherry, banana, apple]
