uitableview - UITableViewController filling cells of different sections with Values -

i'm sure question asked before couldn't find solution it. have uitableviewcontroller static cells, have 4 sections (so far) , each section has 1 cell.

this part of first cell of first section

and corresponding tableviewcell file,

allgemeineproduktdatencell.swift

class allgemeineproduktdatencell: uitableviewcell{      // mark: - outlets     @iboutlet weak var angebotsnametextf: uitextfield!     @iboutlet weak var referenznummer: uitextfield!     @iboutlet weak var modeltextf: uitextfield!     @iboutlet weak var bemerkungtextf: uitextview!     @iboutlet weak var extrastextf: uitextview!     @iboutlet weak var ursprladenpreiseurotextf: uitextfield!     @iboutlet weak var ursprladenpreiscenttextf: uitextfield!     @iboutlet weak var angebotspreiseurotextf: uitextfield!     @iboutlet weak var angebotspreiscenttextf: uitextfield!      // bereich möbel     @iboutlet weak var bereichmoebellabel: uilabel!     @iboutlet weak var bereichmoebelpicker: uipickerview!     @ibaction func showhidebereichmoebelpicker(_ sender: any) {         if bereichmoebelpicker.ishidden{             bereichmoebelpicker.ishidden = false         } else{             bereichmoebelpicker.ishidden = true         }     }      // hersteller     @iboutlet weak var chosenherstellerlabel: uilabel!     @iboutlet weak var herstellerpickerview: uipickerview!     @ibaction func showhideherstellerpicker(_ sender: uibutton) {         if herstellerpickerview.ishidden{             herstellerpickerview.ishidden = false         } else{             herstellerpickerview.ishidden = true         }     }      // anzeigen auch auf eigener webseite     @iboutlet weak var anzeigenauchaufeigenerwebseiteswitch: uiswitch!     @ibaction func anzeigenaufwebsiteswitch(_ sender: any) {     }      // start des angebot     @iboutlet weak var startdesangebotchosendatelabel: uilabel!     @iboutlet weak var startdesangebotdatepicker: uidatepicker!     @ibaction func hideshowstartdesangebotdp(_ sender: any) {         if startdesangebotdatepicker.ishidden{             startdesangebotdatepicker.ishidden = false         } else{             startdesangebotdatepicker.ishidden = true         }     }        func setupallgemeinefields(product: itemsclass){         angebotsnametextf.text = "abed"//product.title         referenznummer.text = product.artikel_nummer         modeltextf.text = product.typ_kategorie     }  } 

imagine have similar files each of cells.

and main view file:

addeditvc.swift

class addeditvc: uitableviewcontroller {      var product_obj: itemsclass!      override func viewdidload() {         super.viewdidload()     }      // mark: - table view data source     override func numberofsections(in tableview: uitableview) -> int {         return 4     }      override func tableview(_ tableview: uitableview, numberofrowsinsection section: int) -> int {         return 1     }      override func tableview(_ tableview: uitableview, cellforrowat indexpath: indexpath) -> uitableviewcell {         if let cell = tableview.dequeuereusablecell(withidentifier: "allgemeineproduktdaten") as? allgemeineproduktdatencell{             cell.setupallgemeinefields(product: product_obj)             return cell         } else{             print("ffffffaaaaaild")             return allgemeineproduktdatencell()         }     } } 

when run application cell blank , cannot see views when comment out cellforrowat function can see outlets fields empty.

how can fill fields of cell object? how should specify cell filled (i need other cells of other sections)

update: overview of tableviewcontroller

thank in advance , sorry such long question

once set prototype cell classes , reuse identifiers, can use below code generate cells. since didn't include exact code classes, skeleton code, should able fill in gaps.

override func tableview(_ tableview: uitableview, cellforrowat indexpath: indexpath) -> uitableviewcell {     switch indexpath.section {     case 0:         let cell = tableview.dequeuereusablecell(withidentifier: "allgemeineproduktdaten") as! allgemeineproduktdatencell         cell.setupallgemeinefields(product: product_obj)         return cell     case 1:         let cell = tableview.dequeuereusablecell(withidentifier: "othercellreuseidentifier") as! othercellclass         //set cell content         return cell     default:         return uitableviewcell()     } }
