any volunteer?......no

since the packager doesn't support Swift framework, maybe you can try this solution: [Hide implementation of swift framework when distributing](https://dahuayuan.wordpress.com/2017/10/12/hide-implementation-of-swift-framework-when-distri/)

跟楼上一样的问题

个人觉得， 代码中的这个强制解包习惯不好， 用的太多， 容易带坏小朋友。`if let` 是Swift的亮点， 应该用这个代替强制解包。
