Hi everyone, I’m encountering a serious reliability issue with message passing in my Safari extension on iOS 18.4.1 and iOS 18.5 In my extension, I use the standard messaging API where the background script sends a message to the content scrip. The content script is listening using: browser.runtime.onMessage.addListener(handler); This setup has been working reliably in previous versions of iOS, but since updating to iOS 18.4.1 and iOS 18.5, I’ve noticed that messages sent from the background script are not consistently received by the content script. From my logs, I can confirm that: The background script is sending the message. The content script’s listener is not always triggered. There are no errors or exceptions logged in either script. It seems as if browser.runtime.onMessage.addListener is either not getting registered in time or failing silently in some instances. This issue is intermittent and does not occur all the time. Has anyone else experienced similar issues in iOS 18.4.1 and 18.5? Are there any known changes or workarounds for ensuring reliable communication between background and content scripts in this version? Any help or insights would be greatly appreciated. Thanks!

Has anyone else run across this after manually renewing an expired developer account? Happens when I go to the "Certificates, Identifiers, & Profiles" page and click on anything. Also unable to download any of the iOS SDK's. Any ideas?

Is it possible to start screen recording (through Control Center) without user prompt? I mean to ask user permission for the first time and after that to start and stop recording programmatically only? I need to record screen only for specific events.

Here's the problem I'm trying to solve: Create an iOS app which can scan the Downloads folder (where airdropped audio files arrive), identify audio media files, and play them, retaining some of its own metadata about them (basically, create textual notes mapped to timestamps and store that information in the apps own storage). I am not able to access that folder. I am able to get a path from NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.downloadsDirectory, FileManager.SearchPathDomainMask(arrayLiteral: FileManager.SearchPathDomainMask.userDomainMask), true) or a URL from NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.downloadsDirectory, FileManager.SearchPathDomainMask(arrayLiteral: FileManager.SearchPathDomainMask.userDomainMask), true) but let fileUrls = try fileManager.contentsOfDirectory(at:downloads, includingPropertiesForKeys: []) fails with an error that the folder does not actually exist, with or without a call to downloadsUrl.startAccessingSecurityScopedResource(). Determining whether this is a permissions issue, or if I'm getting a URL to an application-container local folder that has nothing to do with the one I am looking for is compounded by the fact that if I set the build setting Enable App Sandbox, then deployment to my phone fails with Failed to verify code signature. I have spent hours trying every possible combination of certificates and deployment profiles, and ensured that every possibly relevant certificate is trusted on my phone. Disable app-sandbox and it deploys fine, either with automatic signing or an explicit cert and profile. I have an entitlements file with the following - though, without the ability to enable app sandbox and run it on a phone with actual contents in the downloads folder, it is probably not affecting anything: <key>com.apple.security.files.downloads.read-only</key> <true/> <key>com.apple.security.files.user-selected.read-only</key> <true/> <key>com.apple.security.app-sandbox</key> <true/> So, questions: Should the URL returned by the above call be the Downloads/ folder airdropped to in the first place? Or is it a URL to some app-local folder that does not exist? Does the entitlement com.apple.security.files.downloads.read-only even allow an app to list all files in the downloads directory (presumably asking the user's permission the first time), or does the permission only get requested when using a picker dialog? (the point here is to find any new audio files without making the user jump through hoops) If I could get it deployed with app-sandbox enabled, would the above code work? Backstory: I'm a software engineer, audio plugin author, Logic Pro user and musician. My workflow (and probably many other Logic user's) for work-in-progress music is to airdrop a mix to my phone, listen to it in a variety of places, make notes about what to change, edit - rinse and repeat. For years I used VLC for iOS to keep and play these in-progress mixes - you could airdrop and select VLC as the destination (yes, Logic can add to your Apple Music library, but trust me, you do not want 20 revisions of the same song cluttering your music library and sync'd to all your devices). Last year, the behavior of Airdrop changed so that the target app for audio is always Files, period, wrecking that workflow. While I eventually discovered that, with an elaborate and non-obvious dance of steps, it is possible to copy files into VLC's folders, and make them available that way, it is inconvenient, to say the least - and VLC is less than fabulous anyway - it would be nice to have an app that could associate to-do notes with specific timestamps in a tune, A/B compare sections between old and new versions and things like that. So, figuring sooner or later I was going to get into a car accident futzing with the Files app to listen to mixes while driving, perhaps I should write that app. But the ability to do that at all relies on the ability of an app to list and access the Downloads folder airdropped audio files land in (assuming the user has given permission to access it, but that should be needed once).

The universal links for my apps stopped working. The server where the AASA files where hosted worked on IPV4 exclusively, a few days ago i changed the configuration to IPV6 only. I´ve created new IPV6 entries, renewed all certifactes and deleted all IPV4 entries for the domains. All seemed fine, but at Saturday I realized that my universal links stopped working for new user. What i´ve done to find the issue: Example domain that was used for debugging: "https://developffw.burns.fun" I´ve verified the AASA file is hosted properly by using different browsers and Postman to retrieve it. The file can be accessed and the certificates look fine. Output of curl -v https://developffw.burns.fun/.well-known/apple-app-site-association * Host developffw.burns.fun:443 was resolved. * IPv6: 2a01:4f8:13b:340a::2 * IPv4: (none) * Trying [2a01:4f8:13b:340a::2]:443... * schannel: disabled automatic use of client certificate * ALPN: curl offers http/1.1 * ALPN: server accepted http/1.1 * Established connection to developffw.burns.fun (2a01:4f8:13b:340a::2 port 443) from 2a00:79c0:65c:8b00:80ee:175b:3e2a:1e7d port 61014 * using HTTP/1.x > GET /.well-known/apple-app-site-association HTTP/1.1 > Host: developffw.burns.fun > User-Agent: curl/8.16.0 > Accept: */* > * Request completely sent off < HTTP/1.1 200 OK < Server: nginx/1.22.1 < Date: Mon, 15 Dec 2025 11:34:22 GMT < Content-Type: application/octet-stream < Content-Length: 329 < Last-Modified: Sat, 21 Dec 2024 08:53:11 GMT < Connection: keep-alive < ETag: "676681f7-149" < Accept-Ranges: bytes < { "applinks": { "details": [ { "appIDs": [ "6LN7G8JEA5.burns.FFW-Manager-SwiftUI.Debug"], "components": [ { "/": "/onboard", "?": { "id": "*"}, "?": { "name": "*"}, "?": { "token": "*" } } ] } ] } } * Connection #0 to host developffw.burns.fun:443 left intact I took a look at the headers from the Apple CDN network response.

I can´t find any entry from the Apple servers neither in the default logs nor in the error log entries. The curl attempts are logged with response code 200. I´ve tried sudo swcutil dl -d https://developffw.burns.fun/onboard in the Terminal on my MAC. Output: The operation couldn´t be completed. (SWCErrorDomain error 8.) This indicates to me threre is an issue for the Apple servers accessing my server. But I don´t know what could be the reason. There is no firewall configuration that could block the requests. And there has been no change at all besides the IPV4 / IPV6 protocol change. This issue is the same for all the domain listed on this server. I´v even created a new app for this purpose and created a new AASA entry and associated link. Same issue. I´m pretty much lost here. Everything looks fine from my side. Google assetlinks.json seem to work fine. I would really appreciate some help on how to solve this, i´m at my wits end.

We have a VPN app that uses NEPacketTunnelProvider with includeAllNetworks = true. We've encountered an issue where push notifications are not delivered over Wi-Fi while the tunnel is active in a pre-MFA quarantine state (tunnel is up but traffic is blocked on server side), regardless of whether excludeAPNS is set to true or false. Observed behavior Wi-Fi excludeAPNS = true - Notifications not delivered Wi-Fi excludeAPNS = false - Notifications not delivered Cellular excludeAPNS = true - Notifications delivered Cellular excludeAPNS = false - Notifications not delivered On cellular, the behavior matches our expectations: setting excludeAPNS = true allows APNS traffic to bypass the tunnel and notifications arrive; setting it to false routes APNS through the tunnel and notifications are blocked (as expected for a non-forwarding tunnel). On Wi-Fi, notifications fail to deliver in both cases. Our question Is this expected behavior when includeAllNetworks is enabled on Wi-Fi, or is this a known issue / bug with APNS delivery? Is there something else in the Wi-Fi networking path that includeAllNetworks affects beyond routing, which could prevent APNS from functioning even when the traffic is excluded from the tunnel? Sample Project Below is the minimal code that reproduces this issue. The project has two targets: a main app and a Network Extension. The tunnel provider captures all IPv4 and IPv6 traffic via default routes but does not forward packets — simulating a pre-MFA quarantine state. The main app configures the tunnel with includeAllNetworks = true and provides a UI toggle for excludeAPNS. PacketTunnelProvider.swift (Network Extension target): import NetworkExtension class PacketTunnelProvider: NEPacketTunnelProvider { override func startTunnel(options: [String : NSObject]?, completionHandler: @escaping (Error?) -> Void) { let settings = NEPacketTunnelNetworkSettings(tunnelRemoteAddress: "127.0.0.1") let ipv4 = NEIPv4Settings(addresses: ["198.51.100.1"], subnetMasks: ["255.255.255.0"]) ipv4.includedRoutes = [NEIPv4Route.default()] settings.ipv4Settings = ipv4 let ipv6 = NEIPv6Settings(addresses: ["fd00::1"], networkPrefixLengths: [64]) ipv6.includedRoutes = [NEIPv6Route.default()] settings.ipv6Settings = ipv6 let dns = NEDNSSettings(servers: ["198.51.100.1"]) settings.dnsSettings = dns settings.mtu = 1400 setTunnelNetworkSettings(settings) { error in if let error = error { completionHandler(error) return } self.readPackets() completionHandler(nil) } } private func readPackets() { packetFlow.readPackets { [weak self] packets, protocols in self?.readPackets() } } override func stopTunnel(with reason: NEProviderStopReason, completionHandler: @escaping () -> Void) { completionHandler() } override func handleAppMessage(_ messageData: Data, completionHandler: ((Data?) -> Void)?) { if let handler = completionHandler { handler(messageData) } } override func sleep(completionHandler: @escaping () -> Void) { completionHandler() } override func wake() { } } ContentView.swift (Main app target) — trimmed to essentials: import SwiftUI import NetworkExtension struct ContentView: View { @State private var excludeAPNs = false @State private var manager: NETunnelProviderManager? var body: some View { VStack { Toggle("Exclude APNs", isOn: $excludeAPNs) .onChange(of: excludeAPNs) { Task { await saveAndReload() } } Button("Connect") { Task { await toggleVPN() } } } .padding() .task { await loadManager() } } private func loadManager() async { let managers = try? await NETunnelProviderManager.loadAllFromPreferences() if let existing = managers?.first { manager = existing } else { let m = NETunnelProviderManager() let proto = NETunnelProviderProtocol() proto.providerBundleIdentifier = "<your-extension-bundle-id>" proto.serverAddress = "127.0.0.1" proto.includeAllNetworks = true proto.excludeAPNs = excludeAPNs m.protocolConfiguration = proto m.localizedDescription = "TestVPN" m.isEnabled = true try? await m.saveToPreferences() try? await m.loadFromPreferences() manager = m } if let proto = manager?.protocolConfiguration as? NETunnelProviderProtocol { excludeAPNs = proto.excludeAPNs } } private func saveAndReload() async { guard let manager else { return } if let proto = manager.protocolConfiguration as? NETunnelProviderProtocol { proto.includeAllNetworks = true proto.excludeAPNs = excludeAPNs } manager.isEnabled = true try? await manager.saveToPreferences() try? await manager.loadFromPreferences() } private func toggleVPN() async { guard let manager else { return } if manager.connection.status == .connected { manager.connection.stopVPNTunnel() } else { await saveAndReload() try? manager.connection.startVPNTunnel() } } } Steps to reproduce Build and run the sample project with above code on a physical iOS device. Connect to a Wi-Fi network. Set excludeAPNS = true using the toggle and tap Connect. Send a push notification to the device to a test app with remote notification capability (e.g., via a test push service or the push notification console). Observe that the notification is not delivered. Disconnect. Switch to cellular. Reconnect with the same settings. Send the same push notification — observe that it is delivered.

A message filter extension is only forwarded SMSs by the OS for filtering, iMessages aren't. But what is the situation with RCS messages? Will they be filterable by a message filtering extension?

When attempting to open sysdiagnose logs collected from an iPhone running iOS 26 beta 3 on macOS Console, the application consistently crashes. Crash report has been added for reference. Apple Feedback- FB18834450

In iOS 26 there is a new way of displaying action sheets from the buttons that triggers them. I figured out that in SwiftUI you can just set the confirmationDialog view modifier on the button that triggers it. However, I can't find a way to get this behavior in UIKit when a UIButton triggers an alert. Has anyone got this work? The behavior is mentioned briefly in the "Get to know the new design system" session.

Feedback Ticket: FB13812251 Problem Statement: We are currently facing internet connectivity issue with our VPN application where we try to disconnect the VPN from the Packet Tunnel Network Extension using - (void)cancelTunnelWithError:(nullable NSError *)error. Which API to use to disconnect the VPN from Packet Tunnel as VPN app is not running such that device retains its internet connectivity as soon as VPN disconnects. Configuration: We have configured PacketTunnelProvider with the following settings: (NETunnelProviderManager *)tunnelProvider.protocolConfiguration.includeAllNetworks = YES; (NETunnelProviderManager *)tunnelProvider.protocolConfiguration.excludeLocalNetworks = NO; (NETunnelProviderManager *)tunnelProvider.protocolConfiguration.enforceRoutes = NO; These settings are applied from the VPN app and allow us to successfully establish a VPN connection, with all traffic being routed through the tunnel as expected.We are setting above properties to address local net attack. Issue we are facing: However, we encounter a problem when we attempt to disconnect the VPN from. When we call the following method from PacketTunnel network extension: (void)cancelTunnelWithError:(nullable NSError *)error Upon calling this method, the VPN disconnects as expected, but the device loses all internet connectivity and is unable to access any resources. This is not the desired behavior. Observation : Interestingly, when we call the following method from the app side. The VPN disconnects and the device retains its internet connectivity. [enabledConfig.connection stopVPNTunnel]; We would like to achieve the same behavior when disconnecting the VPN from the Network Extension. So we are looking for an API that could be called from NE without causing any internet connectivity issue. Any guidance on how to resolve this issue would be greatly appreciated.

Hello, I am new to App development, so I am looking for some advice. I want to develop an app for iPhone, which downloads files (pdf, jpg)from a server to the local storage. I also want to get data from the server to be used in my app. This could be a database access or just simple xml files. I want a secure access based on userid and password. Since in a later version, my app should also run on Android Phones, I am reluctant to use iCloud. I was thinking sftp, but that does not seem to be supported for iOS.

’m experiencing an issue where a Text view is unexpectedly truncated with certain font sizes (e.g., .body) on iOS 17 and later. This does not occur on iOS 16. I’ve applied .fixedSize(horizontal: false, vertical: true) to allow the text to grow vertically, but it still doesn’t show the entire content. Depending on the text content or font size, it sometimes works, but not always. How can I ensure the full text is displayed correctly on iOS 17+? Here is a minimal reproducible SwiftUI example: let sampleText1 = """ これはサンプルのテキストです、 ・箇条書き１ ・箇条書き２ であかさたなクロを送り、 アアを『ああああいいいい』フライパンに入れ、あかさたなです😋 """ let sampleText2 = """ 【旬｜最高級】北海道産 生サンマ 釜飯 ----- Aaa iii uuu """ struct ContentView: View { var body: some View { ScrollView { VStack(alignment: .leading, spacing: 10) { HStack { MessageTextView(text: sampleText1) .layoutPriority(100) Spacer() } HStack { MessageTextView(text: sampleText2) .layoutPriority(100) Spacer() } } } } } struct MessageTextView: View { var text: String var body: some View { Text(text) .fixedSize(horizontal: false, vertical: true) .font(.body) .padding(.leading, 16) .padding(.trailing, 16) .padding(.top, 8) .padding(.bottom, 8) } } img1 img2

Hello Team, I try to delete photo from Photos for that i used this method, [[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{ [PHAssetChangeRequest deleteAssets:@[assetToDelete]]; completionHandler:^(BOOL success, NSError *error) { }]; This method pops up a dialog with Don't Allow or Delete. But some time in some iPhones not respond PHAssetChangeRequest deleteAssets method that's why that completionHandler not called because of that i can't perform any operation of PHPhotoLibrary then after. If I restart my iPhone then it works. Many users of my app complained about this issue. I have an iPhone 11 with iOS 15.3. But some iOS 12,14,16 users also face the same issue. So what exact issue is there? Is it related to iOS or a method? Thanks, Ankur

I am trying to make http3 client with Network.framework on Apple platforms. Codes that implement NWConnectionGroup.start with NWListener don't always work with warning below. I assume NWConnectionGroup.newConnectionHandler or NWListener.newConnectionHandler will be called to start connection from the server if it works. nw_protocol_instance_add_new_flow [C1.1.1:2] No listener registered, cannot accept new flow quic_stream_add_new_flow [C1.1.1:2] [-fde1594b83caa9b7] failed to create new stream for received stream id 3 so I tried: create the NWListener -> not work check whether NWConnectionGroup has a member to register or not NWListener -> not work (it doesn't have). use NWConnection instead of NWConnectionGroup -> not work Is my understanding correct? How should I do to set or associate listener with NWConnection/Group for newConnectionHandler is called and to delete wanings? What is the best practice in the case? Sample codes are below.

I have an iPhone 14 Pro. I downloaded the iOS 26 beta and had a SERIOUS error, rendering the phone unusable. I charged it to 60% and kept it plugged in while updating. While updating, I restarted several times at the Apple logo, then at the Welcome screen, and it had quite a few bugs with low battery warnings. When I turned it on, I noticed I had 1% (I thought it was strange). When it was plugged in, it wouldn't charge; it only had 1% left, and it also restarted every 2 minutes. Off-plugged, it did exactly the same thing. In the end, I had to go back to iOS 18.5; I had no problems with this version.

Hello, I have a question about data deserialization using NSKeyedUnarchiver in iOS SDK development. Current Situation: Previously, we were using the NSKeyedUnarchiver.unarchiveObject(with: Data) function We have changed to using the NSKeyedUnarchiver.unarchivedObject(ofClasses:from:) method to deserialize complex objects stored in UserDefaults We need to include all types in the ofClasses parameter, including Swift primitive types as well as various custom classes and structs within the project Questions: Implementation Approach: Is it correct pattern to include all classes defined in the project in the ofClasses array? Is this approach recommended? Runtime Stability: When using this approach, is there a possibility of runtime crashes? Are there any performance issues? Alternative Methods: If the current approach is not the correct pattern, what alternatives should we consider? Current Code Structure: All model classes conform to the NSSecureCoding protocol We use the requiringSecureCoding: true parameter We use a whitelist approach, explicitly listing only allowed classes I would like to know if this structure is appropriate, or if we should consider a different approach. Thank you.

I’m seeing a layout issue in SwiftUI on iOS 26 that only reproduces with specific Accessibility Motion settings. Steps to reproduce 1. Open Settings → Accessibility → Motion. 2. Enable Reduce Motion and Prefer Cross-Fade Transitions. 3. Launch an app with a SwiftUI TextField. 4. Tap the field to show the keyboard. 5. Dismiss the keyboard (tap outside, swipe down, etc.). Expected: After the keyboard is dismissed, the view’s bottom safe area / layout should return to normal. Actual: The view continues to reserve space equal to the keyboard height — as if the keyboard were still visible. UI anchored to the safe area remains shifted upward until the view is reloaded.

Context: I am currently developing an app using the Push-to-Talk (PTT) framework. I have reviewed both the PTT framework documentation and the CallKit demo project to better understand how to properly manage audio session activation and AVAudioEngine setup. I am not activating the audio session manually. The audio session configuration is handled in the incomingPushResult or didBeginTransmitting callbacks from the PTChannelManagerDelegate. I am using a single AVAudioEngine instance for both input and playback. The engine is started in the didActivate callback from the PTChannelManagerDelegate. When I receive a push in full duplex mode, I set the active participant to the user who is speaking. Issue When I attempt to talk while the other participant is already speaking, my input tap on the input node takes a few seconds to return valid PCM audio data. Initially, it returns an empty PCM audio block. Details: The audio session is already active and configured with .playAndRecord. The input tap is already installed when the engine is started. When I talk from a neutral state (no one is speaking), the system plays the standard "microphone activation" tone, which covers this initial delay. However, this does not happen when I am already receiving audio. Assumptions / Current Setup Because the audio session is active in play and record, I assumed that microphone input would be available immediately, even while receiving audio. However, there seems to be a delay before valid input is delivered to the tap, only occurring when switching from a receive state to simultaneously talking. Questions Is this expected behavior when using the PTT framework in full duplex mode with a shared AVAudioEngine? Should I be restarting or reconfiguring the engine or audio session when beginning to talk while receiving audio? Is there a recommended pattern for managing microphone readiness in this scenario to avoid the initial empty PCM buffer? Would using separate engines for input and output improve responsiveness? I would like to confirm the correct approach to handling simultaneous talk and receive in full duplex mode using PTT framework and AVAudioEngine. Specifically, I need guidance on ensuring the microphone is ready to capture audio immediately without the delay seen in my current implementation. Relevant Code Snippets Engine Setup func setup() { let input = audioEngine.inputNode do { try input.setVoiceProcessingEnabled(true) } catch { print("Could not enable voice processing \(error)") return } input.isVoiceProcessingAGCEnabled = false let output = audioEngine.outputNode let mainMixer = audioEngine.mainMixerNode audioEngine.connect(pttPlayerNode, to: mainMixer, format: outputFormat) audioEngine.connect(beepNode, to: mainMixer, format: outputFormat) audioEngine.connect(mainMixer, to: output, format: outputFormat) // Initialize converters converter = AVAudioConverter(from: inputFormat, to: outputFormat)! f32ToInt16Converter = AVAudioConverter(from: outputFormat, to: inputFormat)! audioEngine.prepare() } Input Tap Installation func installTap() { guard AudioHandler.shared.checkMicrophonePermission() else { print("Microphone not granted for recording") return } guard !isInputTapped else { print("[AudioEngine] Input is already tapped!") return } let input = audioEngine.inputNode let microphoneFormat = input.inputFormat(forBus: 0) let microphoneDownsampler = AVAudioConverter(from: microphoneFormat, to: outputFormat)! let desiredFormat = outputFormat let inputFramesNeeded = AVAudioFrameCount((Double(OpusCodec.DECODED_PACKET_NUM_SAMPLES) * microphoneFormat.sampleRate) / desiredFormat.sampleRate) input.installTap(onBus: 0, bufferSize: inputFramesNeeded, format: input.inputFormat(forBus: 0)) { [weak self] buffer, when in guard let self = self else { return } // Output buffer: 1920 frames at 16kHz guard let outputBuffer = AVAudioPCMBuffer(pcmFormat: desiredFormat, frameCapacity: AVAudioFrameCount(OpusCodec.DECODED_PACKET_NUM_SAMPLES)) else { return } outputBuffer.frameLength = outputBuffer.frameCapacity let inputBlock: AVAudioConverterInputBlock = { inNumPackets, outStatus in outStatus.pointee = .haveData return buffer } var error: NSError? let converterResult = microphoneDownsampler.convert(to: outputBuffer, error: &error, withInputFrom: inputBlock) if converterResult != .haveData { DebugLogger.shared.print("Downsample error \(converterResult)") } else { self.handleDownsampledBuffer(outputBuffer) } } isInputTapped = true }

Hi everyone We have brought the iOS development in-house from a consulting firm and have developed a new app that will replace the old one. To minimize disruption for users of the old app during this upgrade, we would like to release the new app as an update to the old one, using the Bundle ID from the old app. It is important to note that the old app has already been released through the App Store. The two apps share no code and are almost incompatible on any points. Is it possible to change the Bundle ID and delete UserDefaults from the old app during the transition to the new app? We look forward to your input!

Facing issue of NSUserDefaults data got cleared on update new version from app store. so all data of user got cleared and user have to login again. I was having app in store with version 1.1.3 and then we have uploaded new version to store with version 1.1.4 but when user download app from store their data was cleared from UserDefaults.so this is big issue in update. need to help. is that apple updated any process on update. Question How Apple change version build in device when we update app from app store. is it uninstall old build and install new build ? Or it is install new version on old version ? Should UserDefaults.standard will delete on update ? Updating Provisioning profile from manual to automatically cause issue on UserDefaults.standard Like UserDefaults got cleared and uuid will change ? Do we have anythings that we can identify specific user as uniq user ? What is better solution to store login data into SQLite store or in UserDefaults as model ? Will appreciate for your help. this is very big issue and login again on update will make app user more effect
