Memory manegment

To understand memory management, particularly in the context of Apple's WWDC sessions, we can look at the session titled "Analyze heap memory" from WWDC 2024. This session provides insights into how heap memory is managed, including the allocation and deallocation processes, and how to identify and fix memory leaks.

Heap memory is created using functions like malloc, and it is responsible for a significant portion of an application's memory footprint. The session discusses the importance of ensuring that all memory in your program is reachable through non-weak references to avoid leaks. Leaked memory is unreachable and cannot be used again, often due to lost pointers or reference cycles.

The session also covers tools for inspecting heap memory issues, such as Xcode's memory graph debugger and Malloc stack logging, which help track memory allocations and identify leaks. Additionally, it discusses managing autorelease pool growth in Swift, which can lead to temporary memory growth.

For more detailed information, you can refer to the session Analyze heap memory (00:01:05) for an overview of heap memory and Explore Swift performance (00:08:29) for insights into memory allocation in Swift.
