Easy and small extension to increase usability of Moya & ObjectMapper for backend abstraction layers. Easily turn a http response into an new-ed, mapped <T: Mappable>

ObjectMapperMoyaExt.swift

// MARK:
// usage example:
// let test: Hello = "{\"hello\": \"world\"}".conform(Hello())
// The class Hello() should extend Mappable, also see ObjectMapper docs.

import ObjectMapper

extension String {
    
    func conform<T: Mappable>(_ model: T) -> T {
        return Mapper<T>().map(JSONString: self)!
    }
    
}

// MARK:
// the following function should be declared in a base model class which handles basic Moya requests.
// this handle function will then a json mapped String object on which later you can call conform.
//
// usage example:
// let test = try BaseModel.toHandle(moya: result).conform(Hello())
//
// print(test.hello)
// world

import Moya

class func toHandle(moya r: Result<Moya.Response, Moya.MoyaError>) throws -> String {
  
    let demat = try r.dematerialize()
    let responseJson = try demat.mapString()
    let resp = demat.response as! HTTPURLResponse
    if resp.statusCode != 200 && resp.statusCode != 204 {
        throw MoyaError.statusCode(demat)
    }

    return responseJson

}
