Before getting into actual coding, let’s have a brief introduction to sets in Swift. Imagine strolling into an art museum and discovering two identical Mona Lisa paintings hanging on the wall. That scenario would almost certainly raise a few eyebrows. Art museums should only have one-of-a-kind stuff, as a set does in Swift.
A set is an unordered collection of distinct items.
There are numerous similarities between sets and arrays, however the key distinctions are as follows:
Sets are an excellent collection type to use when the data we need to store must be unique.
Let’s say we want to keep track of student IDs. We can utilise a set of student IDs because they cannot be duplicated.
In this session, we will learn how to build and use sets in Swift.
Here are some useful tools to help you along your journey!
Setting up an IDE (Integrated Development Environment) can be difficult for beginners. The Online Compiler will enable you to run your code inside your browser without the need to install an IDE. If you need a more detailed explanation of a specific topic, the best place to find answers is in the Official Documentation.
