The video tutorial covers memory management in Swift, focusing on Automatic Reference Counting (ARC). It begins with an overview of memory management and the transition from Manual Retain Release (MRR) to ARC. The tutorial explains how ARC automatically manages memory by tracking object references, preventing memory leaks, and ensuring efficient memory use. A practical example demonstrates ARC in action within a Swift application, highlighting the importance of understanding strong references and memory allocation. The video concludes with a brief mention of using Xcode's Instruments for performance monitoring.
