Hello Justin, As you suggested, I have repeated the tests multiple times, but I was not able to reproduce the crash. As mentioned, it appears to be difficult to encounter the issue consistently. I would also like to share an additional observation: we ran the same application on iPads with iPadOS 18.1 for nearly six months without encountering any crashes. However, after updating the devices to iPadOS 18.6.2, the crashes started occurring. Since the only change during this period was the iPadOS update from 18.1 to 18.6.2, I would appreciate your insight on whether any changes in this OS update could potentially contribute to this behavior?

Hello, Thank you for the suggestions!!. Below is a simplified structure of our current implementation, SceneDelegate.swift import UIKit class SceneDelegate: UIResponder, UIWindowSceneDelegate, UIApplicationDelegate { var viewController:ViewController! func sceneDidBecomeActive(_ scene: UIScene) { viewController.keyboardStatusHandler() } } ViewController.swift import UIKit import Foundation import GameController class ViewController: UIViewController, WKUIDelegate, UINavigationControllerDelegate, AVAudioPlayerDelegate, WKNavigationDelegate, ConnectWebViewDelegate{ override func viewDidLoad() { super.viewDidLoad() //other code NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow), name: UIResponder.keyboardWillShowNotification, object: nil) } @objc func keyboardWillShow(_ notification: NSNotification) { self.keyboardStatusHandler() } func keyboardStatusHandler(){ let isKeyboardConnected = GCKeyboard.coalesced != nil if(!isKeyboardConnected){ //use webView.evaluateJavaScript to send result to Angular } else { //use webView.evaluateJavaScript to send result to Angular } } } As mentioned in my initial message, application is a hybrid app, and the steps described above reflect the code. Based on your suggestion, I agree that this issue may be related to a memory management problem. I will attempt to reproduce the crash using both the Zombies Instrument and the Address Sanitiser as suggested.

Hello, I'm sorry, i forgot to mentioned the iPad OS version in the initial post. Crash happen in iPad OS is 18.6.2 tablet. Is the snippet in your original post your code's only interaction with the GCKeyboard API? To this question , Yes this is the only function that called GCKeyboard, For the places we called "keyboardStatusHandler()" function is like below, In the Scenedelgate , inside sceneDidBecomeActive(_:) Via a NotificationCenter observer registered in the view controller, triggered when the keyboard is shown: NotificationCenter.default.addObserver(self, selector: #selector(XXXXX), name: UIResponder.keyboardWillShowNotification,object: nil)

CrashReportUpdate.txt Hello Justin, Thank you for your reply!!. when i look at the full crash report, in the com.apple.main-thread there is a [_UIKeyboardStateManager updateDelegatePasteSupport] line. i attached the whole crash report to the message. Your help and suggestions would be greatly appreciated.!

@phidev same phenomenon occurs in the app that we are building(iOS 18.3.1) and is there any update on the bug report? Also if you able to fix it in a different way i would really like i you can share it!!

[quote='807167022, DTS Engineer, /thread/765186?answerId=807167022#807167022'] I think you’ll have to look at the network side of this. [/quote] Oh really, i will ask this from the network side. But the thing is OS related dialog box returning from NEHotspotConfigurationManager apply method with "Cannot Connect to ABCWiFi" is showing. So i'm a bit confused with the result of currentSSIDs() method. is there any explanation for this from iOS ?

Thank you for details and explanation. [quote='806989022, DTS Engineer, /thread/765186?answerId=806989022#806989022'] What sort of network requires you to set these parameters? [/quote] Actually it is a private network and to connect with this private network i need to setup all IP Address, SubNetMask, Router and DNS server address. [quote='806989022, DTS Engineer, /thread/765186?answerId=806989022#806989022'] You can monitor the current networking state to see if the join request was successful. [/quote] Like you suggested i already tried with monitoring the current connected Wifi SSID using the below code. So then i can figure the connected and not connected status correctly. let eapSetting = NEHotspotEAPSettings() eapSetting.username = self.username eapSetting.password = self.password eapSetting.supportedEAPTypes = [NEHotspotEAPSettings.EAPType.EAPPEAP.rawValue as NSNumber] eapSetting.trustedServerNames = ["ABC"] NEHotspotConfigurationManager.shared.removeConfiguration(forSSID: self.ssid) let hotspotConfiguration = NEHotspotConfiguration(ssid: self.ssid, eapSettings: eapSetting) manager.apply(hotspotConfiguration){ (error) in if self.currentSSIDs().first == self.ssid { print("Success") return } else { print("Error") return } } func currentSSIDs() -> [String] { guard let interfaceNames = CNCopySupportedInterfaces() as? [String] else { return [] } return interfaceNames.flatMap { name in guard let info = CNCopyCurrentNetworkInfo(name as! CFString) as? [String:AnyObject] else { return nil } guard let ssid = info[kCNNetworkInfoKeySSID as String] as? String else { return nil } return ssid } } I only need to test it for three cases, Wrong SSID Wrong UserName Wrong Password when i test for above test cases output from currentSSIDs() method is like below, Wrong SSID →　[] Wrong UserName →　[] Wrong Password →　["SSID1"] if currentSSIDs() method's output is like [] for above three case i was able to handle my error part without problem. But for Wrong Password it is return as connected. So i would like to know whether my code is wrong or is there a another way to catch these three cases?

Thank you for the quick reply, Yeah previous thread is really old. So i made a new one with same topic, subtopic, and tags. New thread: https://developer.apple.com/forums/thread/765186

Thank you for the reply. I was able to connect using the above flow that motioned. Now i'm trying to handle the error in the code.When i try even OS Dialog showing with "Cannot connect" response return as Success. https://forums.developer.apple.com/forums/thread/96834?page=2 I read the above thread and what i can understand from that is it's a bug in the os method. So does this problem fixed on latest iOS version? or is there a way to handle this problem? I wrote my error handling code bellow→ NEHotspotConfigurationManager.shared.removeConfiguration(forSSID: self.ssid) let hotspotConfiguration = NEHotspotConfiguration(ssid: self.ssid, eapSettings: eapSetting) manager.apply(hotspotConfiguration){ (error) in if let error = error { print("Error") return } else { print("Success") return } }

I mad a mistake and this phenomenon is happening in iPad 10th generation and iPad OS is ** 17.2 **. Environment: ・Device: iPad 10th generation ・OS：iPad OS 17.2 ・Native App : Swift 5

Does this means the bug is fixed in 17.2? https://developer.apple.com/documentation/safari-release-notes/safari-17_2-release-notes Fixed a cache miss bug in DOMCache that triggered service worker fetch errors. (115740959) (FB13188943) I'm also getting the same problem but it's in WKWebView loading Angular App. Does WKWebView problem also going to be fixed from above bug fix in 17.2?

i tried using NEHotspotEAPSettings in the below code and i and getting some errors. let eapSettings = NEHotspotEAPSettings() eapSettings.isTLSClientCertificateRequired = true eapSettings.ttlsInnerAuthenticationType = .eapttlsInnerAuthenticationEAP eapSettings.supportedEAPTypes = [NEHotspotEAPSettings.EAPType.EAPTLS.rawValue as NSNumber] guard let certificateURL = Bundle.main.url(forResource: "certificate-name", withExtension: "crt") else { print("Certificate file not found.") return } do { let certificateData = try Data(contentsOf: certificateURL) eapSettings.setTrustedServerCertificates([certificateData]) //AA } catch { print("Failed to load certificate data:", error.localizedDescription) return } configuration = NEHotspotConfiguration(ssid: ssidValue, eapSettings: eapSettings) //BB NEHotspotConfigurationManager.shared.apply(configuration!) { (error) in if let error = error { print("Failed to connect to WiFi network: \(error.localizedDescription)") } else print("Successfully connected to WiFi network.") } } Errors: 2023-06-20 17:44:40.079743+0900 [874:203915] [] NEHotspotEAPSettings invalid certificate data type //(comes from AA) 2023-06-20 17:44:40.080467+0900 [874:203915] [] NEHotspotConfiguration identity not provided //(comes from BB) 2023-06-20 17:44:40.080576+0900 [874:203915] [] NEHotspotConfiguration invalid EAP settings. //(comes from BB) Failed to connect to WiFi network: invalid EAP settings. i would like to know if there is a specific certificate datatype that needed to use with NEHotspotEAPSettings?

Thank you for the reply. I was bale to connect to Wi-Fi network programmatically using NEHotspotConfigurationManager(using SSID and Password). i would also like to know is there a specific function that we can use to connect to Wi-Fi using (SSID,Password and Certificate) in NEHotspotConfigurationManager?
