The Swift standard library includes a variety of collection types such as arrays, dictionaries, and sets, which are all part of the Swift language's core features. These collections allow for operations like iteration and element access using indices. The standard library also provides implementations of many standard algorithms, such as map, filter, and reduce, which are familiar to those with experience in functional programming. Swift's closure syntax, which allows for succinct code, is particularly useful when working with these algorithms.
For more detailed exploration of Swift's features and design, you can refer to the session A Swift Tour: Explore Swift’s features and design (00:15:03). This session covers various aspects of Swift, including its collection types and the use of protocols to build abstractions over these types.
