Creating a generic method with AlamoFire in Swift

Question

I am using AlamoFire for my API calls, and have something like this all over my project:

static func login(userName: String, password: String) -> User {
          


        

Answer 1

you can use a BaseObject to do this easy :

class BaseUser: ResponseObjectSerializable {
    var valueHandle : ((BaseUser)->())?
    var errorHandle : ((NSError)->())?

    required init?(response: NSHTTPURLResponse, representation: AnyObject) {

    }
}



func sendRequest<T:BaseUser>(method: Alamofire.Method, urlString: String, parameters: [String: AnyObject]?) -> T {
    let res : T
    Alamofire.request(method, urlString, parameters:parameters)
        .validate()
        .responseObject { (response: Response<T, NSError>) in
            switch response.result {
            case .Success(let value):
                res.valueHandle?(value)
            case .Failure(let error):
                res.errorHandle?(error)
            }
    }

    return res
}

class can hold the handle ,and with the baseobj you don't need to write them again and again by using protocol
