I’m Karoly Nyisztor and welcome to Introduction to Algorithms and Data Structures in Swift.
Let's check whether you've got all it takes to enjoy and benefit from this course.
In this section we are going to talk about computational complexity. The Big-O notation is a mathematical model used in computer science to describe the efficiency of algorithms as a function of their input size.
The best way to understand the Big-O thoroughly is via code examples. Therefore, we are going to illustrate each concept using live Swift coding.
In this lecture, we are going to talk about the Constant Time complexity. We'll also implement Swift functions that execute in constant time.
I'm going to show how what recursion is. We're going to analyze some examples and we'll even implement a recursive data structure.
We'll start the study of basic sorting algorithms with the selection sort algorithm. We are going to implement it in Swift. We’ll also visualize how selection sort works and we’ll analyze the time complexity of this algorithm.
Finally,we are going back up the theory with performance tests.
Insertion sort is a basic sorting algorithm, which works by analyzing each element and inserting it into its proper place, while larger elements move one position to the right.
Insertion sort has quadratic time complexity. However, the performance of the insertion sort is largely affected by the initial order of the elements in the sequence.
- You should be comfortable with concepts like variables, methods, and classes
- Basic knowledge of Xcode
- A desire to learn

Take a closer look at algorithms and data structures and learn how to work with them to more efficiently approach software development with Swift. "Introduction to Algorithms and Data Structures in Swift 5" is a straightforward guide to solving coding problems more efficiently.
In this comprehensive course, author Károly Nyisztor helps to familiarize yourself with algorithmic thinking and code optimization techniques. He explains each concept using easy-to-understand examples. He focuses on the practical application, using hands-on Swift code examples you can use for reference and practice.
Although the demos are implemented in Swift, the lessons can be applied to any programming language.
Throughout the course, Károly walks you through several demo applications to demonstrate the power of algorithms and the importance of picking the right solution.
The Big O notation
Constant, linear, polynomial and logarithmic time complexity
Understanding recursion and avoiding pitfalls
Case studies for finding faster solutions
Built-in Swift collection types
When to use a Set, an Array or a Dictionary?
Implementing selection sort, insertion sort, and bubble sort
Advanced sorting: quicksort and merge sort
The study of algorithms and data structures is fundamental to any programmer who plans to develop software systems that are scalable and performant.
"Introduction to Algorithms and Data Structures in Swift 5" is the perfect course for you if you're interested in bringing your Swift coding skills to the next level.

"This course gives me a much deeper understanding of how to write efficient and effective Swift code. It addresses things not covered in the various other crash courses on iOS development, things not apparent at first. I'd published several simple apps and games already but discovered I needed this information when I started working on a much more complex app and needed to understand how to improve my app's performance, so I searched for information on that and discovered this very helpful course." - Minni K. Ang
"LOVE this instructor! His explanations are always clear and accurate, and his pacing is spot-on. Fantastic!" - Glenn
