Autoreleasepool

The concept of autoreleasepool is discussed in the session titled "Analyze heap memory" at WWDC 2024. In this session, it is explained that autorelease pools are used to manage the memory of objects in Objective-C, and they can also be relevant in Swift when interacting with Objective-C APIs. Autorelease pools delay the release of objects, which can lead to memory growth if not managed properly, especially in loops where objects are autoreleased into the same pool. To mitigate this, it is recommended to define a nested local autorelease pool scope to narrow down object lifetimes and reduce memory usage.

For more details, you can refer to the section on managing autorelease pool growth in Swift, which starts at 10:34 in the session "Analyze heap memory".
