How can I extract the JobSeekerID with UserDefaults swift 3

Question

I'm trying to fetch the jobSeeker ID from my api using the userDefaults but I'm having a nil as response.

Basically, what I'm doing is:

Creating a helper class as NSObject and saving the token (which is working unlike my userID).

class helper: NSObject {

class func restartApp(){
    guard let window = UIApplication.shared.keyWindow else {return}

    let storyBoard = UIStoryboard(name: "Main", bundle: nil)
    let viewController : UIViewController

    if getApiToken() == nil {
        //go to auth screen
        viewController = storyBoard.instantiateInitialViewController()!
    } else {
        //go to main screen
        viewController = storyBoard.instantiateViewController(withIdentifier: "profileNavigationController")
    }

    window.rootViewController = viewController

    UIView.transition(with: window, duration: 0.5, options: .transitionFlipFromTop, animations: nil, completion: nil)

}

class func saveApiToken(token: String){

    //save api token to UserDefailts

    let def = UserDefaults.standard
    def.setValue(token, forKey: "token2")
    def.synchronize()
    restartApp()
}

class func saveJobSeekerIdDefault(defaultID: String){

    //save userDefaultID to UserDefailts

    let defID = UserDefaults.standard
    defID.setValue(defaultID, forKey: "default_profile_id")
    defID.synchronize()

 restartApp()
}

class func getApiToken() -> String? {
    let def = UserDefaults.standard
    return def.object(forKey: "token2") as? String
}

class func getJobseekerID() -> String? {
    let defID = UserDefaults.standard
    return defID.object(forKey: "default_profile_id") as? String
}
}

After this, the initializers:

class UserProfileDefaults{

var userID : String
var defaultProfileType : String
var defaultProfileID : String

init?(profileDefaultsDict: [String:Any]){
    guard let userID = profileDefaultsDict["user_id"] as? String,
    let defaultProfileType = profileDefaultsDict["default_profile_type"] as? String,
    let defaultProfileID = profileDefaultsDict["default_profile_id"] as? String else {return nil}

    self.userID = userID
    self.defaultProfileID = defaultProfileID
    self.defaultProfileType = defaultProfileType
}
}

Then, I used Alamofire to fetch the id:

 class func userProfileDefault(completion: @escaping( _ error: Error?, _ userProfileDefaults: UserProfileDefaults?) -> Void){

    let url = URLs.profileDefaultsUrl

    guard let api_token = helper.getApiToken() else {
        completion(nil, nil)
        return
    }

    let headers: HTTPHeaders = [
        "Authorization": "Bearer \(api_token)",
        "Accept": "application/json"
    ]


    Alamofire.request(url, method: .get, encoding: URLEncoding.default, headers: headers)
        .responseJSON { response in

            switch response.result{
            case .failure(let error):
                completion(error, nil)
                print(error)
            case .success(let result):
                let json = JSON(result)
                print(json)

                //Data - JobSeekerDefaults
                guard let jobSeekerDefaults = json["data"].dictionaryObject else {
                    completion(nil, nil)
                    return
                }

                let userDefaultsData = UserProfileDefaults(profileDefaultsDict: jobSeekerDefaults)

                //print("Test userID01: \(userDefaultsData?.userID)")


                helper.saveJobSeekerIdDefault(defaultID: "97")

                    completion(nil, userDefaultsData)


            }
    }
}

I thought this was the way to get this data but I'm having nil as return. I really would like someone to help me because I'm stuck on this for a long time and it's driving me crazy.

Look more precisely on your server response most probably you mismatch it. In UserProfileDefaults class initialisation set breakpoint on guard and print in console value of profileDefaultsDict like po profileDefaultsDict. Make sure that model you provided in initialisation in compliance with server side
