swift3 - How to get Mappable model class data in another ViewController in swift 3 -

i had model class of mappable type in pass data api in firstviewcontroller. want access model class data in secondviewcontroller. how can use data in secondviewcontroller. here code:

import objectmapper  class userprofileresponse: mappable {  var data:userprofiledata? var success: bool? var error: string?  required init?(map: map){  }  func mapping(map: map) {     data <- map["data"]     success <- map["success"]     error <- map["error"] } }  class userprofiledata: mappable {  var address: string? var joindate: string? var phone: string? var policyname: string? var imageurl: string? var name: string? var policyno: string? var title: string?  required init(map: map){  }  func mapping(map: map) {     address <- map["address"]     joindate <- map["joindate"]     phone <- map["phone"]     policyname <- map["policyname"]     imageurl <- map["imageurl"]     name <- map["name"]     policyno <- map["policyno"]     title <- map["title"] }  } 

my firstviewcontroller sending data model class

 func getuserprofiledatafromapi(){     //calling method api class     userprofileapi{completion in self.getprofiledata(result: completion)} }  func userprofileapi(completion:@escaping (_ result:userprofiledata)->()) { let defaultobject = userdefaults.standard let headertoken = defaultobject.object(forkey: kheadertoken) as! string let headers = ["authorization": headertoken]  alamofire.request(kprofileurl, method: .post, encoding: jsonencoding.default, headers: headers)     .validate()     .responseobject{ (response: dataresponse<userprofileresponse>) in         switch response.result{         case .success:             let value = response.result.value             completion((value?.data)!)         case .failure(let error):             print(error.localizeddescription)         } } } func getprofiledata(result: userprofiledata){    // here data in firstviewcontroller }  how can userprofiledata in secondviewcontroller.  

create signleton class can populate userprofiledata api response.

class userprofilemanager {     static var userprofile: userprofiledata?   private static var sharedmanager: userprofilemanager = {         let shared = userprofilemanager()         return shared     }()      class func shared() -> userprofilemanager {         return sharedmanager     } } 

you can access userprofiledata singleton stays during first time if quit , launch wont there store info in userdefaults.
