you need fetch data of selected row in custom uipickerview , send uitableviewcontroller, i.e.

1. fetching , passing data

var tablecontroller: tableviewcontroller?  @ibaction func additem(sender: uibutton) {     if let tablecontroller = self.tablecontroller     {         tablecontroller.items.append(items[self.picker.selectedrow(incomponent: 0)])         tablecontroller.tableview.reloaddata()         self.navigationcontroller?.pushviewcontroller(tablecontroller, animated: true)     } } 

2. uitableviewcontroller

class tableviewcontroller: uitableviewcontroller {     var items = [string]()      override func tableview(_ tableview: uitableview, numberofrowsinsection section: int) -> int     {         return items.count     }      override func tableview(_ tableview: uitableview, cellforrowat indexpath: indexpath) -> uitableviewcell {         let cell = tableview.dequeuereusablecell(withidentifier: "cell", for: indexpath)         cell.textlabel?.text = items[indexpath.row]         return cell     } }
