This is one of the ways to solve it. We solved it in a week session called Saturday Night Coder. Change Development Info Maybe we set the setting iOS 14.0. Please change it into iOS 13.0. And write a code import UIKit // Pencilkit import PencilKit class ViewController: UIViewController {   override func viewDidLoad() {     super.viewDidLoad()     // Do any additional setup after loading the view.           let canvas = PKCanvasView(frame: view.frame)     view.addSubview(canvas)     canvas.tool = PKInkingTool(.pen, color: .black, width: 30)           // PKToolPicker     if let window = UIApplication.shared.windows.first {       if let toolPicker = PKToolPicker.shared(for: window) {         toolPicker.addObserver(canvas)         toolPicker.setVisible(true, forFirstResponder: canvas)         canvas.becomeFirstResponder()       }             }         }   override func viewDidAppear(_ animated: Bool) {       super.viewDidAppear(animated)       let canvasView = PKCanvasView(frame: view.frame)       view.addSubview(canvasView)       guard       let window = view.window,       let toolPicker = PKToolPicker.shared(for: window) else { return }       toolPicker.setVisible(true, forFirstResponder: canvasView)       toolPicker.addObserver(canvasView)       canvasView.becomeFirstResponder()     }     }
