What is swift tuples?

A Swift tuple is a collection of values of different types that are grouped together as a single compound value. Tuples allow developers to return multiple values from a function or to group together related values that can be passed as a single parameter.

Tuples can contain any number of values, and each value can be of a different data type. The values in a tuple can be accessed using dot notation or by using index numbers. Tuples can also be used to assign multiple variables at once.

Here's an example of a tuple that contains two values - a string and an integer:

let myTuple = ("Hello", 42)

To access the values in the tuple, you can use dot notation:

let myString = myTuple.0 // "Hello"
let myInt = myTuple.1 // 42

You can also give names to the values in a tuple:

let namedTuple = (name: "John", age: 30)

To access the named values in the tuple, use dot notation with the names:

let name = namedTuple.name // "John"
let age = namedTuple.age // 30

Tuples are lightweight and are a useful way to group related values together.
