I have 3 UIButtons, and 3 different variables:     var firstSign: Sign?     var secondSign: Sign?     var thirdSign: Sign? My goal is to set Title for each button with each variable in random order. I did it for first one and second one, but can't figure out how to add third title. The second one goes as title for Button 2 & 3. This is Quiz game app so first button is additionally marked as rightAnswer.         rightAnswerPlace = arc4random_uniform(3)+1         var button: UIButton = UIButton()         for i in 1...3 {             button = view.viewWithTag(i) as! UIButton             if (i == Int(rightAnswerPlace)) {                 button.setTitle(firstSign!.name, for: .normal)             } else {                 button.setTitle(secondSign!.name, for: .normal)             }         } I know the code above is not completed, but I can't figure out how to add thirdSign variable into the for loop as third button title.

Hello all, Im working on my project and stuck at point of searching through the tableView. I can't figure out how to change my code to filter position in my Categories (name and code). At this moment Search bar filters only Categories name, without category content. Array: var categories: [Category] = [         Category(name: "Name", sign: [Sign(code: "code", name: "name", description: "description", picture: "picture"), My searchbar func which filter only categories ([Category]) func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {         filteredCategories = []         if searchText == "" {             filteredCategories = categories         } else {             for signs in categories {     if signs.name.lowercased().contains(searchText.lowercased()) {                     filteredCategories.append(signs)                 }             }         }         self.tableView.reloadData()     } Thanks for your advices
