Swift 中的 @autoreleasepool 类似功能是什么？

语法如下:

autoreleasepool {
  /* code */ 
}

不幸的是，苹果的WWDC 2014视频似乎不再可用.如果它回来了，WWDC 2014年会议视频418"用仪器改进你的应用程序"中会介绍它.

swift documentation目前没有任何有用的东西.但是你可以在NSAutoreleasePool和Advanced Memory Management Programming Guide的Obj-C运行时参考中找到很多好的信息.

101 Auto Release Pools are no-longer as relevant today as they were in the past. Modern code should use Automatic Reference Counting which does not use release pools at all. However there's still a lot of legacy code, including in Apple's frameworks, that use auto release pools as of 2021. If you're doing any kind of batch process on images as one example, you probably should be using an 100 block.
