To encourage Apple's Vision code to use its pool of IOSurfaces instead of creating new ones, you should focus on optimizing memory management and reducing unnecessary allocations. Here are some relevant tips from the sessions:

  1. Managing Autorelease Pool Growth: In the session Analyze heap memory, it is suggested to define a nested local autorelease pool scope to narrow down object lifetimes. This can help in reducing the accumulation of objects and the need for additional memory pages.

  2. Concurrency and Task Management: In the session Discover Swift enhancements in the Vision framework, it is recommended to use concurrency to process multiple images efficiently. Limiting the number of concurrent tasks can help manage memory usage better.

  3. Efficient Texture Use: In the session Optimize your 3D assets for spatial computing, optimizing the use of texture memory is discussed. Efficiently packing textures and using compression can help reduce memory footprint.

By implementing these strategies, you can help ensure that the Vision framework reuses IOSurfaces more effectively, reducing the need to create new ones.
