How to Filter a Swift Array based on a Condition?

Swift Array – Filter Elements based on Condition

To filter elements of a Swift Array, call filter() method on this array and pass the predicate/condition to the filter() method.

filter() method returns a new array with the elements of the original array, that satisfy the given condition.

Only those elements that satisfy the given condition, or return true for the given condition, will make it to the resulting array.

In the following program, we will take an array of numbers, and filter only those numbers that are greater than 10.

main.swift

var arr = [1, 99, 6, 74, 5]
let result = arr.filter { $0 > 10 }
print("Original Array : \(arr)")
print("Filtered Array : \(result)")

Output

Concluding this Swift Tutorial, we learned how to filter a given array based on a specific condition.
