Swift: Checking if a Set Contains a Specific Element

In Swift, you can check whether a set contains a specific element or not by using the contains() method. Its syntax is as follows:

set.contains(element)

Where set is the name of the set you want to check and element is the value you want to look for. The method returns a Boolean value of true or false.

Example:

let mySet: Set<String> = ["Sling", "Academy", "Swift", "iOS"]

// check if mySet contains "Swift"
if mySet.contains("Swift") {
    print("mySet contains 'Swift'")
} else {
    print("mySet does not contain 'Swift'")
}

Output:

mySet contains 'Swift'
