asyncimage cache

The concept of caching images, including the use of AsyncImage in Swift, is touched upon in the context of memory management and optimization in the WWDC sessions. Here are some relevant details:

1. Caching Thumbnails:

   • In the session Analyze heap memory, there is a discussion about caching photo thumbnails. The method in question was caching thumbnails based on the current time instead of the file's creation date, leading to persistent growth of thumbnails in memory. This was fixed by correctly caching based on the file's creation date.

2. Concurrency and Memory Management:

   • The session Discover Swift enhancements in the Vision framework discusses optimizing vision APIs with Swift concurrency. It highlights the importance of managing memory when processing multiple images concurrently, which is relevant when dealing with image caching and processing.

3. Handling Memory Growth:

   • Another part of the session Analyze heap memory addresses persistent memory growth, which can occur if images or thumbnails are not properly managed and deallocated.

For more detailed information on these topics, you can refer to the following sessions and their chapters:

• Analyze heap memory (Chapters: Persistent memory growth overview, Resolving leaks of Swift closure contexts)
• Discover Swift enhancements in the Vision framework (Chapters: Optimize with Swift Concurrency)

These sessions provide insights into effective memory management practices, which are crucial when implementing caching mechanisms like AsyncImage.
