A set is an unordered collection of unique values in Swift. It is implemented as a hash table where values are hashed to determine their positions within the collection.
Creating a set:
Accessing and modifying a set:
Iterating over a set:
Performing set operations:
Set operations allow you to combine, find common elements, find exclusive elements, or subtract elements from two sets.
Set membership and equality:
Set membership can be checked using the `isSubset(of:)` and `isSuperset(of:)` methods. The `isDisjoint(with:)` method checks if two sets have any common elements. Set equality can be checked using the `==` operator.
Summary: Sets in Swift are unordered collections of unique values. They can be created, modified, and accessed using various methods and operators. Set operations and membership checks make working with sets efficient and convenient.
