it didn't work because populate list of types, not values. should include reference tableview , reload everytime populate list. try this:

import uikit  class schedavolontario: uiviewcontroller, uitableviewdatasource, uitableviewdelegate {    var nome: string?   var cognome : string?   var sede : string?   var progetto : string?   var datainizioservizio : string?   var datafineservizio : string?   var licenze : string?   var malattie : string?   var codvolontariostring : string?    var guestinfolist: [string] = []    // connect outlet table view in storyboard   @iboutlet weak var guestinfotableview: uitableview!    override func viewdidload() {     super.viewdidload()      populateguestinfolist()     guestinfotableview.reloaddata()   }    func populateguestinfolist() {     if let nome = nome {       guestinfolist.append(nome)     }      if let cognome = cognome {       guestinfolist.append(cognome)     }      if let sede = sede {       guestinfolist.append(sede)     }      if let progetto = progetto {       guestinfolist.append(progetto)     }      if let datainizioservizio = datainizioservizio {       guestinfolist.append(datainizioservizio)     }      if let datafineservizio = datafineservizio {       guestinfolist.append(datafineservizio)     }      if let licenze = licenze {       guestinfolist.append(licenze)     }      if let malattie = malattie {       guestinfolist.append(malattie)     }      if let codvolontariostring = codvolontariostring {       guestinfolist.append(codvolontariostring)     }   }    func tableview(_ tableview: uitableview, numberofrowsinsection section: int) -> int {     return guestinfolist.count   }     func tableview(_ tableview: uitableview, cellforrowat indexpath: indexpath) -> uitableviewcell {     let cell = tableview.dequeuereusablecell(withidentifier: "cell", for: indexpath)     cell.textlabel?.text = guestinfolist[indexpath.row]     return cell   } }
