Tool to convert from Swift to objective-c
提问by developer82
I know most of the questions are about converting from objective-c to swift, but I'm looking for a tool that can convert a swift code to objective-c. When searching all I find is objective-c to swift.
我知道大多数问题都是关于从objective-c 转换为swift，但我正在寻找一种可以将swift 代码转换为objective-c 的工具。在搜索时，我发现的只是objective-c 到swift。
Yes - I know I can put swift code inside objective-c project with a bridge-header - that's not what I'm looking for.
是的 - 我知道我可以将 swift 代码放入带有桥头文件的 Objective-c 项目中 - 这不是我想要的。
I need a tool that converts swift code to objective-c code. Is there such thing?
我需要一个将 swift 代码转换为 Objective-c 代码的工具。有这种事吗？

There is no such tools for converting Swift code to Objective-C. There are some reasons. One is because Objective-C is a semantic subset of Swift, i. e. Objective-C doesn't have any equivalent of some fundamental features of Swift such as Generics, Algebraic data types, Pattern matchingand other. Theoretically it is possible to make, but generated Objective-C code should be boilerplate and inefficient.
没有这样的工具可以将 Swift 代码转换为 Objective-C。有一些原因。一个是因为 Objective-C 是 Swift 的语义子集，即 Objective-C 没有任何等效于 Swift 的一些基本特性，例如泛型、代数数据类型、模式匹配等。理论上是可以的，但是生成的 Objective-C 代码应该是样板文件并且效率低下。
