swift 协议添加一个枚举或者结构体泛型

直接上代码

public protocol CodingTableKey {
    static func crateTB();
}

public protocol TableDecodable {
    
    associatedtype CodingKeys: CodingTableKey
    typealias Properties = CodingKeys
    
}

extension TableDecodable{
    static func test(){
        self.CodingKeys.crateTB()
    }
}

class People: TableDecodable {
    enum CodingKeys:CodingTableKey {
        static func crateTB() {
            
        }
        
        case name
    }
    
    
    
}
