Swift Array – Filter Even Numbers

To filter even numbers from a Swift Array, call filter() method on this array and pass the predicate/condition that the element is even.

filter() method returns a new array with the numbers of the original array, which are only even.

Example

In the following program, we will take an array of numbers, and filter only those numbers that are even.

main.swift

var arr = [1, 99, 6, 74, 5]
let result = arr.filter { $0 % 2 == 0 }
print("Original Array : \(arr)")
print("Filtered Array : \(result)")
