Does it work with swift2 and iOS 9?

[athalay]

I'm willing to use this library with iOS9 and swift through cocoapods.

Unfortunately deserialization json to object always give null result:

//DTO class:

import ObjectMapper

class ResponseResult : Mappable
{
    var IsSuccessful: Bool?;
    var ErrorMessage: String?;
    var SuccessMessage: String?;

        required init?(_ map: Map){

            }

 func mapping(map: Map) {

        IsSuccessful <- map["IsSuccessful"]
ErrorMessage <- map["ErrorMessage"]
SuccessMessage <- map["SuccessMessage"]

    }
}

// USAGE:

Alamofire.request(.POST, "http://192.168.0.12:57336/Account/LogOnMobile", parameters: loginParams)
            .responseString(completionHandler: { (request, response, json) -> Void in

                debugPrint(json.value);

                let user = Mapper<ResponseResult>().map(json.value)
                });

Yes ObjectMapper works with swift 2.0 and iOS 9.

Can you post your JSON response? Otherwise its difficult to figure out what is going wrong.

Sorry, I'll paste my JSON here (more properties are coming back than which are present in my model class):

OK, got the problem.

Instead of

let user = Mapper<ResponseResult>().map(json.value)

, I have to use

let user = Mapper<ResponseResult>().map(json.value!)

(using "!" for json.value, so it's not an optional).

Is this a bug, or user-error? :)

[tristanhimmelman]

Ahh I just spotted your error.

ObjectMapper has different functions which you can use for mapping. Currently you are getting a string response from Alamofire. Since the response is a string you need to unwrap the optional due to the map function definition: public func map(JSONString: String) -> N?

However, you can also use Alamofire to return a JSON object (I recommend this approach). Given the JSON object you would use this function: public func map(JSON: AnyObject?) -> N?

If you choose to use my recommendation, your code would look like this:

Alamofire.request(.POST, "http://192.168.0.12:57336/Account/LogOnMobile", parameters: loginParams)
        .responseJSON { (request: NSURLRequest?, HTTPURLResponse: NSHTTPURLResponse?, result: Result<AnyObject>) -> Void in
        let user = Mapper<Forecast>().map(result.value)
}

Lastly, since you are using Alamofire and ObjectMapper together, I recommend you check out https://github.com/tristanhimmelman/AlamofireObjectMapper. It automatically converts your Alamofire responses into models using ObjectMapper.

Thanks a lot, Tristan, though maybe it could be a CR for consideration that inside you check whether the passed in string is optional or not, and if it is, then you handle this case inside. So others don't really have to mind what do they pass in.
