How to check if Two Arrays have Same Elements (Regardless of Order) in Swift

How to check if Two Arrays have Same Elements (Regardless of Order) in Swift ?

Answer

To check if two arrays have the same elements regardless of order in Swift, you can sort both arrays and then compare them using the == operator.

✐ Examples

1 Arrays with Same Elements (Order Ignored)

In this example,

We create two arrays named arr1 and arr2 with the same elements but in different order.
We sort both arrays using the sorted() method.
We then compare the sorted arrays using the == operator.
Finally, we print the result to the console.

Swift Program

let arr1 = [1, 2, 3]
let arr2 = [3, 1, 2]

let sortedArr1 = arr1.sorted()
let sortedArr2 = arr2.sorted()

let isEqual = sortedArr1 == sortedArr2
print(isEqual)

Output

true

2 Arrays with Different Elements (Order Ignored)

In this example,

We create two arrays named arr3 and arr4 with different elements.
We sort both arrays using the sorted() method.
We then compare the sorted arrays using the == operator.
Finally, we print the result to the console.

Swift Program

let arr3 = [1, 2, 3]
let arr4 = [4, 5, 6]

let sortedArr3 = arr3.sorted()
let sortedArr4 = arr4.sorted()

let isEqual = sortedArr3 == sortedArr4
print(isEqual)

Output

false
