Working with Sets in Swift

Sets are a fundamental data structure in Swift that allow you to store unique values in a collection. Unlike arrays, sets do not have a specific order, and each value is unique within the set. Sets provide a fast and efficient way to perform operations like membership testing and removing duplicates from a collection.

Here's an example of how you can work with sets in Swift:

// Creating a Set
var fruits: Set = ["Apple", "Orange", "Banana"]

// Adding an Element to a Set
fruits.insert("Grapes")

// Removing an Element from a Set
fruits.remove("Orange")

// Checking if a Set contains a specific element
if fruits.contains("Apple") {
    print("The set contains Apple")
}

// Iterating over a Set
for fruit in fruits {
    print(fruit)
}

// Performing Set Operations
let vegetables: Set = ["Carrot", "Tomato", "Broccoli"]
let commonElements = fruits.intersection(vegetables)
print(commonElements)}

Summary

Sets in Swift provide a convenient way to work with unique values and perform set operations efficiently. By using sets, you can easily manage collections of data without worrying about duplicates or maintaining a specific order.
