get next page's item in iOS (SWIFT)

how can i do the same in iOS ???

    public class MyForm { final DataHandler dataHandler; BackendlessCollection<Note> data;

    MyForm() {
    dataHandler = new DataHandler(this);

    void setData(BackendlessCollection<Note> data) { = data;
    //render new set of data

    //‘Fetch Data’ Button click handler
    public void fetchData() {
    BackendlessDataQuery dataQuery = new BackendlessDataQuery();

    Backendless.Data.of(Note.class).find(dataQuery, dataHandler);

    //‘Next Page’ Button click handler
    public void fetchNext() {

    void setError(BackendlessFault fault) {
    //Toast.makeText(getContext(), “” + fault.getMessage(), Toast.LENGTH_LONG).show();

    class DataHandler implements AsyncCallback<BackendlessCollection<Note>> {
    final MyForm form;

    DataHandler(MyForm form) {
    this.form = form;

    public void handleResponse(BackendlessCollection<Note> notes) {

    public void handleFault(BackendlessFault fault) {
    the above code is from android platform and i want to do the same in swift , am not able to find the classes which i used in my android , like i dont what is DataHandler in iOS its no where in entire backendless class…

well it was easy than i expected it to be , just wanted to know if is it a correct way of doing this or not thats why am posting my solution here :

this is my first fetch action
var fetchResults = BackendlessCollection()

func queryNotesFromServer(){

let dataQuery = BackendlessDataQuery()
dataQuery.whereClause = whereClause
let dataStore =


response: { (result: BackendlessCollection!) -> Void in
let notes = result.getCurrentPage()

//handle here first loaded page
self.fetchResults = result

error: { (fault: Fault!) -> Void in
print(“Server reported an error: (fault)”)

and after that my further fetch request’s action : which is loading 5 items per request
func loadNextPage(){

fetchResults.nextPageAsync({ (nextResult : BackendlessCollection!) in

let notes = nextResult.getCurrentPage()

//handle here next loaded page
self.fetchResults = nextResult

if self.fetchResults.getCurrentPage().count < 5 {


{ (error : Fault!) in

print(“Server reported an error: (error)”)


please do let me know if its the correct way or not for achieving the paged data retrieval
