Lay the foundations of algorithms and data structures in Swift 5. Level up your Swift 5 coding skills.

Get a step-by-step, example-filled guide to algorithms and data structures. Companion eBook included.

This course is perfect for both beginners interested in understanding how computers are able to process data and experts who want to review the basics.

The better you understand how algorithms and data structures work, the more successful you'll be as a programmer. After taking this course, you'll master the fundamentals of algorithms and data structures. You'll also understand the time complexity of different algorithms, and we'll dive into code optimization techniques and sorting algorithms.

I'll explain each concept using easy-to-understand examples. We'll focus on the practical application, using hands-on code examples you can use for reference and practice. 

"Introduction to Algorithms and Data Structures in Swift 5" is a straightforward guide to solving coding problems more efficiently. Although the demos are implemented in Swift, the lessons can be applied to any programming language.

Throughout the course, I'll walk you through several demo applications to demonstrate the power of algorithms and the importance of picking the right solution.

What qualifies me to teach you?
I have more than 25 years of software development expertise. I've worked for companies like Apple, Siemens, and SAP.
As a software architect, I have designed and built several enterprise systems and frameworks, including core components of Siemens Healthcare's syngo image processing system. I'm one of the senior software architects behind the SAP Cloud Platform SDK for iOS, a framework built by Apple and SAP. I currently hold twelve patents related to inventions in the field of mobile computing.

Topics include:

  • Algorithmic thinking

  • The Big O notation

  • Constant, linear, polynomial, and logarithmic time complexity

  • Understanding recursion and avoiding pitfalls

  • Case studies for finding faster solutions

  • Generics

  • 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
