reverse() method reverses the elements of the array in place.

reversed() method creates a new array with the elements of the original array reversed, and returns this new array.

In this tutorial, we will go through examples covering reverse() and reversed() methods.

In the following program, we will take an array, and reverse the order of its elements using reverse() method.

main.swift

</>

Copy

var arr = [1, 2, 3, 8, 25, 99]
arr.reverse()
print(arr)

Output

In the following program, we will take an array, and reverse the order of its elements using reversed() method.

main.swift

</>

Copy

var arr = [1, 2, 3, 8, 25, 99]
var arrReversed: [Int] = arr.reversed()
print("Original Array: \(arr)")
print("Reversed Array: \(arrReversed)")

Output

In this Swift Tutorial, we learned how to reverse a Swift Array using reverse() or reversed() method.
