Silent push notifications not working on some iOS devices
I send APNs notifications to my devices with the CloudKit dashboard. I test with two devices; Device with Silent Push Working Successfully: iOS version 16.5.1 (c), Model iPhone Xs Silent Push Failed Device: iOS version 15.3.1, Model iPhone Xr Normal alert notifications work successfully on both devices. But I can't see any log in my project even though silent push is sent successfully on one device. What I've Checked: content-available is set to 1. My app is not in kill state, it is in foreground or pending in the background. When I send simple notifications, I can see logs in my swift project and notifications on physical devices without any problem. No, my certificate has not expired and if there was a problem with it, I would not be able to see the normal notifications. My phone is not in power saving mode and the “Background App Refresh” option is turned on in the app's settings. Both devices in charging state. App capabilities: Background Modes is enabled with Remote Notifications, Background Fetch, Background Processing. CloudKit Dashboard After Sending Silent Push: My AppDelegate Class In Swift Project: import SwiftUI import UIKit import UserNotifications class AppDelegate: UIResponder, UIApplicationDelegate { var window: UIWindow? func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool { UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { granted, error in if granted { DispatchQueue.main.async { UIApplication.shared.registerForRemoteNotifications() } } } return true } func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) { let tokenParts = deviceToken.map { data in String(format: "%02.2hhx", data) } let token = tokenParts.joined() print("Device Token: \(token)") } func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) { print("Failed to register: \(error)") } func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) { logInfo("Received Push Notification: \(userInfo)") if let aps = userInfo["aps"] as? [String: AnyObject], aps["content-available"] as? Int == 1 { logInfo("This is a silent push notification") //DO SOME WORK completionHandler(.newData) } completionHandler(.newData) } }

App Icon Shows Black Background in iOS 18 Settings Dark Mode
After updating to iOS 18, I've noticed that my app's icon displays correctly on the home screen but appears with a black background in the 'Settings > Apps' section when Dark Mode is active. The icon currently has a non-transparent gradient orange background, and I haven't set up a separate icon for Dark Mode. Has anyone else experienced this issue, or does anyone have suggestions for how to ensure the app icon looks the same in Dark Mode as it does in Light Mode?
