do {      var urlmov = cell.videourl!     let jpgdelete = cell.urljpg     var valuesmov = urlresourcevalues.init()      if ((alertalcon.textfields!.first?.text?.characters.count)! >= 15){=           let tmalcon = uialertcontroller(title: "too long", message: "the name entered long", preferredstyle: .alert)          let tmcancelal = uialertaction(title: "cancel", style: .cancel, handler: {action in              self.present(alertalcon, animated: true, completion: nil)             })           tmalcon.addaction(tmcancelal)         self.present(tmalcon, animated: true, completion: nil)      }      if ((alertalcon.textfields!.first?.text?.characters.count)! <= 14){          valuesmov.name = (alertalcon.textfields!.first?.text)! + ".mp4"         try urlmov.setresourcevalues(valuesmov)         try! filemanager().removeitem(at: jpgdelete!)     } }   catch {     swift.print("error in rewrite ", error) }

and view made:

let rectangle = cgrect(x: 0, y: 0, width: parent.view.frame.width, height: 88) let myview : uiview = uiview(frame: rectangle) myview.center = self.center myview.backgroundcolor = uicolor.white self.contentview.addsubview(myview) self.contentview.sendsubview(toback: myview)
