“不能从非开放类继承"迅速 [英] "Cannot inherit from non-open class" swift

问题描述

从Xcode 8 beta 6开始，我现在在其定义模块之外收到编译错误无法从非开放类(类)继承"

As of Xcode 8 beta 6 I now get the compile error "Cannot inherit from non-open class (Class)" outside of its defining module"

我继承的类是一个单独的Swift框架的一部分，但是我的项目针对Xcode 8 beta 5进行了编译.我需要更改什么才能使项目再次编译?

The class I was inheriting from was part of a separate Swift framework but my project compiled for Xcode 8 beta 5. What do I need to change to get my project to compile again?

推荐答案

我自己找到了答案.

在Swift 3中，您现在可以将一个类标记为open而不是public，这允许模块外部的文件对该类进行子类化.

In Swift 3 you can now mark a class as open instead of public this allows files outside of the module to subclass that class.

只需将模块类中的public替换为open.

Simply replace public in your module class with open.

参考此处.
