How to Check if Array contains Specific Element in Swift?

Swift Array – Check if Specific Element is Present

To check if an Array contains a specific element in Swift, call contains(_:) method on the Array and pass the specific element as argument.

The syntax to call contains() method to check if the specific element e is present in the Array array is

array.contains(e)

In the following program, we will take an integer array and check if the integer "8" is present in this array.

main.swift

var array = [2, 4, 6, 8, 10]
var e = 8
var isElementPresent = array.contains(e)
print("Is elemnet present in array? \(isElementPresent)")

Output

Is elemnet present in array? true
Program ended with exit code: 0

Since element 8 is present in the Array array, contains() method returned true.

Now, let us take an element such that it is not present in the array.

main.swift

var array = [2, 4, 6, 8, 10]
var e = 15
var isElementPresent = array.contains(e)
print("Is elemnet present in array? \(isElementPresent)")

Output

Is elemnet present in array? false
Program ended with exit code: 0

Since e is not present in array, contains() method returned false.

In this Swift Tutorial, we learned how to check if an Array contains a specific element in Swift programming.
