What types of collections have you worked with in practice?

In iOS development practice, it is common to work with various collections from the Swift standard library:

• Array — an ordered list of elements that can be accessed by index. Used for storing sequences of data.
• Set — an unordered collection of unique elements, useful for quick search and eliminating duplicates.
• Dictionary — a collection of key-value pairs where keys are unique. Often used for storing data with fast access by key.

Example of using Array:

var fruits: [String] = ["Apple", "Banana", "Cherry"]
fruits.append("Date")
print(fruits[0]) // Apple

Collections are also used in UIKit and SwiftUI for displaying lists, for example, UITableViewDataSource works with data arrays.
