How to add objects of entity class(DTO's value) using “addAttributeMappings” in RestKit?

Question

My json response contains not only strings, but also array of DTO. Object mapping is not happening in the right format.

json response body :

{
  \"

The below solved my issue :

In LoanDetailServiceClass,

func getLoanDetails(success: @escaping((_ loanDetailModel: LoanDetailModel?) -> ()),
                failure: @escaping ((_ error:String) -> ())) {

    // Define mappings
    let postMapping: RKObjectMapping = RKObjectMapping(for: LoanDetailModel.self)
    postMapping.addAttributeMappings(from: ["id","componentName"])

    let dTOListMapping: RKObjectMapping = RKObjectMapping(for: DynamicTableDetailDTOList.self)
    dTOListMapping.addAttributeMappings(from: ["fieldName",
                                               "fieldType",
                                               "label"])
    postMapping.addRelationshipMapping(withSourceKeyPath: "DynamicTableDetailDTOList" ,
                                       mapping: dTOListMapping)

    // Define response decriptor
    let statusCodes = RKStatusCodeIndexSetForClass(RKStatusCodeClass.successful)
    let resDescriptor = RKResponseDescriptor(mapping: postMapping, method: RKRequestMethod.GET, pathPattern: nil, keyPath: nil, statusCodes: statusCodes)

    // Create object manager
    let url = URL(string: baseURL)
    let jsonPlaceholderManager = RKObjectManager(baseURL: url)
    jsonPlaceholderManager?.addResponseDescriptor(resDescriptor)
    RKObjectManager.setShared(jsonPlaceholderManager)

    // Perform GET request
    RKObjectManager.shared().getObjectsAtPath(appendedURL, parameters: nil, success: { (operation, mappingResult) -> Void in
        let loanDetailModel: LoanDetailModel = mappingResult!.firstObject as! LoanDetailModel
        success(loanDetailModel)

    }) { (operation, error) -> Void in
        failure((error?.localizedDescription)!)
    }
}
