When will you use arrays in your code?

Arrays are used when it is necessary to store an ordered collection of homogeneous elements, accessed by index. Typical scenarios include:

• Storing a list of objects where order matters (e.g., a list of users, a list of tasks in an application).
• Operations requiring quick access to elements by their position.
• Iterating over all elements of a collection to perform the same operation on each.
• Implementing stacks or queues (although more specialized data structures may be used for stacks and queues).

Example of creating and using an array in Swift:

// Creating an array of strings
var todoList: [String] = ["Buy groceries", "Pay bills", "Read a book"]

// Adding an element
todoList.append("Exercise")

// Accessing an element by index
let firstTask = todoList[0] // "Buy groceries"

// Iterating over elements
for task in todoList {
    print(task)
}
