问题描述

Assuming that nothing is referencing it anymore, will an object be released from memory after being removed from an array? 假设不再有任何引用，将对象从数组中删除后是否将其从内存中释放出来？

Should I set it to nil before removing it? 我应该在删除它之前将其设置为nil吗？

Yes it will be released, Swift uses ARC . 是的，它将被发布，Swift使用ARC 。 If an object is added to an array and then removed. 如果将对象添加到数组然后删除。 It will be cleared from memory. 它将从内存中清除。 You will not need to it to nil before removing. 删除之前，无需将其设置为零。
