How to check if Arrays are Equal in Swift?

Swift – Check if Arrays are Equal

Two arrays are said to be equal if they contain the same elements in the same order.

To check if two arrays are equal in Swift, use Equal To == operator. Equal To operator returns a Boolean value indicating whether two arrays contain the same elements in the same order. If two arrays are equal, then the operator returns true, or else it returns false.

The syntax to use Equal to operator to check if arrays arr1 and arr2 are equal is

arr1 == arr2

Example

In the following program, we take two arrays in arr1 and arr2. We shall check if these two arrays are equal using equal to operator.

main.swift

var arr1 = ["apple", "mango", "cherry"]
var arr2 = ["apple", "mango", "cherry"]

if (arr1 == arr2) {
    print("Two arrays are equal.")
} else {
    print("Two arrays are not equal.")
}

Output

Now let us take elements in the arrays arr1 and arr2 such that the respective elements are not equal.

main.swift

var arr1 = ["apple", "mango", "cherry"]
var arr2 = ["apple", "avacado", "cherry"]

if (arr1 == arr2) {
    print("Two arrays are equal.")
} else {
    print("Two arrays are not equal.")
}

Output

Conclusion

In this Swift Tutorial, we learned how to check if two arrays are equal using Equal to operator.
