Method cannot be marked @objc because the type of the parameter 1 cannot be represented in Objective

错误：Method cannot be marked @objc because the type of the parameter 1 cannot be represented in Objective-C

场景：swift中有需要OC调用的方法，前面加@objc ，编译器报错

翻译：方法中有一个参数没有变成OC

解决方案，确保每个参数（主要包括，类和枚举）都已经桥接 Objective-C

注意，枚举在文件内，在类外面，所以要在枚举前加@objc

 

@objc enum GHNFollowBtnModule: Int {
    case column = 0
    case topic = 1
    case author = 2
    case none = 999
}
