问题 I am using local notification using the UserNotifications framework in which I have two action buttons. Now I want to perform one task upon selecting that action button. My query is whether I need to run this task in the background? As I am sending this local notification based on geofence triggering when my application is not even running and in a killed state. Configure User Notification Center localCenter.delegate = self localCenter.requestAuthorization(options: [.alert, .badge, .sound]) {

问题 I have added a WKwebview in SwiftUI via UIVewRepresentable. I am having difficulties getting some buttons to make the web view go back and go forward. Below is the two classes I have made but I am not even getting print to work ( maybe a bug? ). import SwiftUI import WebKit struct Webview : UIViewRepresentable { let request: URLRequest func makeUIView(context: Context) -> WKWebView { return WKWebView() } func updateUIView(_ uiView: WKWebView, context: Context) { uiView.load(request) } func

问题 After updating to Xcode 11.5, I cannot import My Universal framework. Basically, I have created one framework and also generated the universal framework. The framework was compiled in the lower version of Swift (Swift 5.1). It worked fine previously.

Module compiled with Swift 5.1.2 cannot be imported by the Swift 5.2.4 compiler I have already marked the Build Libraries for

问题 I know there are plenty of similar questions and answers, and I reviewed them all, but still cannot find the solution. Despite of removing a scheduled notification from UNUserNotificationCenter it still gets triggered. I create local notification as follows: let aDF = DateFormatter() aDF.dateFormat = "yyyy-MM-dd HH:mm:ss" var identifierST = "" if update == true { identifierST = myCoreDataEntity.notificationUID! } else { identifierST = aDF.string(from: Date()) } let notif =
