ios - Read Data from Firebase and put it in Cells in TableView -

so want amount of holes uialert , put them in database , receive them in other view controller fill example 18 cells each have title 1 - 18, don't know how example 18 cells , cell 1 have title 1 , cell 2 have title 2 , on.

here's database:

structure

here's want add holes tableview:

class holesviewcontroller: uitableviewcontroller {      //todo add cells firebase inside courses.child      //g/l input data in next viewcontroller       //firebaserefrences     var ref = firdatabasereference.init()      var holes: [firdatasnapshot]! = []      override func viewdidload() {          //viewdidload            //refrences firebase          ref = firdatabase.database().reference()         let coursesref = ref.child("courses")         var holes: [firdatasnapshot]! = []           print()            //snapshot          coursesref.observeeventtype(.childadded, withblock: { snapshpt in              //self.courses.append(snapshpt)             //self.tableview.reloaddata()             //print(snapshpt.childsnapshotforpath("holes"))              self.holes.append(snapshpt.childsnapshotforpath("holes"))             print(self.holes)              //self.tableview.reloaddata()         })       }      override func viewdidappear(animated: bool) {          //viewdidappear     }      override func tableview(tableview: uitableview, numberofrowsinsection section: int) -> int {          return self.holes.count      }      override func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {          let cell: uitableviewcell! = self.tableview.dequeuereusablecellwithidentifier("holecell")          let holessnap = self.holes[indexpath.row]          let holes = holessnap.value          /*           ??????          */          return cell     }      override func tableview(tableview: uitableview, caneditrowatindexpath indexpath: nsindexpath) -> bool {          return true     }   } 

here's data holes from:
