Answer 1

You can just pass the closure(function) as parameter

swift
func request(requestPath:String, requestParams:Any, callback:((Result) -> Void)) { 
    ... 
}

Where Result will be the type of your response.

Thanks for reply but finally solution

class HttpRequest<Request, Response>
{
    private var serviceBase:String = "http://192.168.1.1/api";
    func request(path:String, model: Request, success: @escaping((_ response: [Response]?) -> ()), failure: @escaping ((_ error:String) -> ()) {
         // code here..
    }
}
