Swift Sets

Swift Set

Swift Set is an unordered collection of unique elements.

There is no order for elements that are stored in a Set. Therefore, we cannot use index to access elements of a Set.

The following is a simple example of a Set named fruits.

let fruits: Set = ["apple", "banana", "cherry", "mango"]

Basics

The following tutorials cover how to create a Set, access properties of a Set, iterate over the elements, etc.

Checks

• Swift – Check if Set is Empty
• Swift – Check if Element is present in Set

Comparing Sets

• Swift – Check if two Sets are Equal
• Swift – Check if two Sets are Not Equal
• Swift – Check if this Set is Subset of Another Set
• Swift – Check if this Set is Superset of Another Set
• Swift – Check if two Sets are Disjoint

Find

• Swift – Find Minimum Element in a Set
• Swift – Find Maximum Element in a Set

Update Transform
