ios - Swift - Firebase getting all keys and store them into array -

i have firebase database structure:

main ----- name 1 --------value 1 --------value 2 --------value 3 ----- name 2 --------value 1 --------value 1 --------value 1 

i'm trying key values , storing array of custom class.

my custom class has init:

init(name: string, photo: string) { self._name = name self._photo = photo } 

so in view controller have:

var array = [customclass]() let ref = database.database().reference().child("main")  func getinfo(){     ref.observesingleevent(of: .value) { (snapshot) in         var arraytemp = [customclass]()         child in snapshot.children {             let snap = child as! datasnapshot             let name = snap.key             let custom = customclass(name: name, photo: "")             arraytemp.append(custom)         }         self.array = arraytemp         self.collectionview.reloaddata()     } }    func collectionview(_ collectionview: uicollectionview, cellforitemat indexpath: indexpath) -> uicollectionviewcell {     if let cell = collectionview.dequeuereusablecell(withreuseidentifier: "cell", for: indexpath) as? cell {         let custom: custom!             custom = array[indexpath.row]             cell.configurecell(custom)               return cell     } else {     return uicollectionviewcell()     } } 

and here cell:

class cell: uicollectionviewcell {  @iboutlet weak var thumb: uiimageview! @iboutlet weak var namelbl: uilabel!  var custom: customclass!   func configurecell(_ custom: customclass) {      self.custom = custom     namelbl.text = self.custom.customname.capitalized     var url = url(string: self.custom.photourl)     if url == nil {         url = url(string: "")     }     thumb.sd_setimage(with: url)  } 

}

my issue if print name have values db when reload collection view see number of item correct name first element repeated x time... help?

to fix issue :

func numberofsections(in collectionview: uicollectionview) -> int {     return 1 }  func collectionview(_ collectionview: uicollectionview, numberofitemsinsection section: int) -> int {     return self.array.count }
