Hi. I know that UIApplication#keyWindow is deprecated since iOS/iPadOS 13.0. But now (iOS/iPadOS 16.5), UIWindow#isKeyWindow and didBecomeKeyNotification seem deprecated, too. isKeyWindow is always true and didBecomeKeyNotification is never triggered. Is my understanding right? And if so, since what version of iOS/iPadOS are they deprecated?

Hi. I implemented a broadcast upload extension and it requests local notifications. The local notification works normally on broadcastStarted(withSetupInfo:), but the Banner of the local notification does not work on processSampleBuffer(_: with:) though its Notification Center works normally. What am I missing? Here is my code snippets. container app class AppDelegate: NSObject, UIApplicationDelegate { func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool { // Override point for customization after application launch. requestAuthorization() ... } private func requestAuthorization() { let center = UNUserNotificationCenter.current() center.requestAuthorization(options: [.alert]) { granted, error in if let error = error { // Handle the error here. print(error) } if granted == true { center.delegate = self center.getNotificationSettings(completionHandler: { setting in print(setting) }) } else { print("not permitted") } } } } upload extension class SampleHandler: RPBroadcastSampleHandler { override func broadcastStarted(withSetupInfo setupInfo: [String : NSObject]?) { super.broadcastStarted(withSetupInfo: setupInfo) notification(title: "Upload Extension", body: "broadcastStarted") ... } override func processSampleBuffer(_ sampleBuffer: CMSampleBuffer, with sampleBufferType: RPSampleBufferType) { super.processSampleBuffer(sampleBuffer, with: sampleBufferType) ... if some condition { notification(title: "Upload Extension", body: "processSampleBuffer") } } private func notification(title: String, body: String) { let content = UNMutableNotificationContent() content.title = title content.body = body let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: nil) let notificationCenter = UNUserNotificationCenter.current() notificationCenter.add(request) { error in if error != nil { print(error) } } } }

Hi. I want to implement the code below using vDSP. for i in a.indices { a[i] = n[i] == 0.0 ? 0.0 : b[i] / n[i] } This code is slow. Are there any good implementation using Accelerate framework?
