There is error when launch app which use Pencil kit When I try with iOS15 simulator or Xcode editor preview it crashed Here is error message Library not loaded: /usr/lib/swift/libswiftPencilKit.dylibI Reason: tried: '/Users/.../Products/Debug-iphonesimulator/libswiftPencilKit.dylib' (no such file) There is no problem with iOS14.5 simulator

I have widget for schedule app I tried get my widget updated according to user's schedule Here is actual code for 'get timeline' in timeline provider note that I make 2 entries for each user schedule ( one for notice start of schedule one hour early, the other for notice end of schedule) let entryBeforehand = ScheduleEntry(     date: oneHourEarly,     holiday: holidays?[day.toInt],     scheduleTable: contractTable(start: day, tablePtr: &schedules)) entries.append(entryBeforehand) let entryExpired =  ScheduleEntry(     date: dateExpired,     holiday: holidays?[day.toInt],     scheduleTable: contractTable(start: day, tablePtr: &schedules)) entries.append(entryExpired) But both entries can't trigger widget updating itself

I'm implementing swift UI image view overlaid by canvas view in Pencil kit Because Pencil kit is in UIKit I create another class for creating gesture recognizer Thankfully it work so I can zoom or pan on canvas view and the underling image view is responding But unlikely using Gesture and GestureState in SwiftUI It cause memory issue when I just zoom image it take almost 1GB Here is my code class GestureDelegate: NSObject, ObservableObject, UIGestureRecognizerDelegate { var zoomScale: CGFloat { fixedZoomScale * gestureZoomScale } var fixedZoomScale: CGFloat = 1 @Published var gestureZoomScale: CGFloat = 1 private(set) lazy var pinchGestureRecognizer: UIPinchGestureRecognizer = { let pinchGesture = UIPinchGestureRecognizer(target: self, action: #selector(pinchImage(_:))) pinchGesture.delegate = self return pinchGesture }() Here is canvas view in UIViewRepresentable There is pan gesture recognizer also but there is no problem with pan gesture struct BlurMaskView: UIViewRepresentable { private let canvas: PKCanvasView private let gestureDelegate: GestureDelegate func makeUIView(context: Context) -> PKCanvasView { canvas.drawingPolicy = .anyInput canvas.tool = tool canvas.backgroundColor = .clear canvas.addGestureRecognizer(gestureDelegate.pinchGestureRecognizer) canvas.addGestureRecognizer(gestureDelegate.panGestureRecognizer) return canvas }
