Swift Memory Management Masterclass

Understanding how memory management works is essential to becoming an iOS developer! It's required for building performant applications and is a very common topic on iOS interviews.

Memory management is the essential practice of efficiently allocating and releasing computer program memory resources. It ensures program stability and performance by preventing memory leaks and unnecessary resource usage. In some languages like Swift and Java, automatic memory management, such as ARC, simplifies this process, while in others like C and C++, manual management is required. Regardless of the approach, effective memory management is fundamental in creating reliable and efficient software. 


How this course works 

Below is a collection of videos that explain everything you need to know about memory management in Swift. The videos increase in skill level, with the first videos addressing high level topics for new programmers. The final videos in the series are much more technical and in-depth. These videos have been extracted from larger courses, which we highly recommend watching in full here.


Let's jump in... 



Now that we have a basic understanding of Object Oriented Programming (OOP) in Swift, let's take a look at the different types of objects and classes that we can allocate and deallocate into memory.





Great job! Understanding the difference between these object types is crucial to becoming a skilled iOS developer. Although we only touched the basics here, we will come back and take a deeper look at these concepts later in this course!

Next, let's talk about [weak self]. The difference between strong and weak references is one of the most challenging topics in iOS. In the next video, we will look at an example of why we write this code. In the videos afterward, we will full break down what's happening.





Alright! Now, it's time to take everything that we've learned already, and dive DEEP into these topics. This next video is quite possible the most important Swift video I've ever created. It's long... but worth it!

Trust me.





Wow that was a lot! I hope you're still with me...

We're now entering into the last section of the course. In the following videos we will discuss Actors and Global Actors. While these are not nearly as common as Classes and Structs, they are very important to understand.





Alright! Great job! We have one final video here, which is a quick video explaining how strong and weak references work in the world of Swift Concurrency (with async / await).




Well done! Now you're an expert at memory management in Swift! 


I hope this FREE course was worth your time and helped you on your journey to becoming an expert iOS developer! If you enjoyed it, please don't forget to follow us on YouTube!
