The Swift standard library defines a base layer of functionality for writing Swift programs, including:
Fundamental data types such as Int, Double, and String
Common data structures such as Array, Dictionary, and Set
Global functions such as print(_:separator:terminator:) and abs(_:)
Protocols, such as Collection and Equatable, that describe common abstractions.
Protocols, such as CustomDebugStringConvertible and CustomReflectable, that you use to customize operations that are available to all types.
Protocols, such as OptionSet, that you use to provide implementations that would otherwise require boilerplate code.
