i think it's helpful you..

func tableview(_ tableview: uitableview, willdisplay cell: uitableviewcell, forrowat indexpath: indexpath) {     let lastsectionindex = tableview.numberofsections - 1     let lastrowindex = tableview.numberofrows(insection: lastsectionindex) - 1     if indexpath.section ==  lastsectionindex && indexpath.row == lastrowindex {         // print("this last cell")         let spinner = uiactivityindicatorview(activityindicatorstyle: .red)         spinner.startanimating()         spinner.frame = cgrect(x: cgfloat(0), y: cgfloat(0), width: tableview.bounds.width, height: cgfloat(44))          self.tableview.tablefooterview = spinner         self.tableview.tablefooterview?.ishidden = false     } }

tablefooterview should hide when data load. when above function isn't work can prefer link.
