How do I create and initialize arrays, sets, and dictionaries in Swift?

In Swift, you can create and initialize arrays, sets, and dictionaries easily. Below are examples for each of these data structures:

Arrays


        // Creating and initializing an array
        var fruits: [String] = ["Apple", "Banana", "Cherry"]

        // Accessing an element
        let firstFruit = fruits[0] // "Apple"

Sets


        // Creating and initializing a set
        var uniqueNumbers: Set = [1, 2, 3, 4, 5]

        // Adding an element
        uniqueNumbers.insert(6)

Dictionaries


        // Creating and initializing a dictionary
        var ages: [String: Int] = ["Alice": 25, "Bob": 30]

        // Accessing a value
        let aliceAge = ages["Alice"] // 25
