Like many/most developers, I gave Connect the info required to comply with the DSA. Perhaps unlike most, I always give unique email addresses so that I can easily track the source of abuse. Yesterday I finally had a phish come in to my DSA address claiming "Message blocked" and doing the standard click-to-login-for-details FOMO bait. So, yep, DSA just becomes yet another public database that malicious actors can use to target you. It would be really nice if Apple provided a way to supply our contact info only for legitimate business purposes. Mail Privacy Protection (or similar) for this would be a start.

Hi everyone, I’m developing a health-related mobile app and considering using EAS Update to deliver over-the-air (OTA) updates for JavaScript code and assets. Before implementing this, I want to ensure that this approach complies with Apple App Store policies, especially given the sensitivity of health-related apps. Here are my concerns: Does using EAS Update (OTA) align with Apple’s guidelines regarding app updates and dynamic behavior changes? Are there specific rules or restrictions for health apps using OTA updates that I should be cautious of? Could this approach be flagged as violating Apple’s policies on app integrity, especially those requiring updates to go through the App Store review process? I’d greatly appreciate any insights, advice, or references to Apple’s official documentation regarding OTA updates for apps distributed through the App Store. Thanks in advance for your help!

I have a use case where I want to retrieve a third-party access token and pass it between servers to allow different services to make API calls. But when looking through the third-party docs, I found this note: "One important aspect to understand about access tokens is that most tokens are portable. However, Apple does not allow moving tokens to servers." It's found here: https://developers.facebook.com/docs/facebook-login/guides/access-tokens#portabletokens Does anyone have more information on what this means? Has anyone had issues with passing tokens between clients/servers or servers/servers on Apple devices? Thanks!

Hi! I've just opened Xcode and found that I can't build my app anymore. The error was about signing. Basically, there's no team in my account. Also, I've found that all my certificates have been revoked! I created my dev account a month ago and released only one macOS app. It's SecFolder (it's not self-promotion!!!). App not even in the App Store. I planned to self-distribute it. I'm in a little shock right now since I've just launched and had my first users. And of course, my app is now gone from their Macs, screaming "malware" popup in their faces now :( Since my app is all about paranoia security, this is basically a death sentence for my project... Could someone with experience in the Apple dev ecosystem help me understand what might have gone wrong? Why might Apple think that my app is malware or something? P.S. My app is about Advanced File Access Control for macOS. It gives user complete control over which applications can access specified by user files and folders

can i get transferid by /auth/usermigrationinfo api before transfered app? https://developer.apple.com/documentation/sign_in_with_apple/transferring-your-apps-and-users-to-another-team#Generate-the-transfer-identifier

Hi everyone, I'm encountering an issue where the background location indicator remains visible on the status bar even though I have set the location permissions to Never for my app in the system settings. Despite taking all the necessary steps to stop location tracking (including stopping updates, geofencing, and other location-related services), the indicator still appears. This seems to be a bug since everything has been turned off on my end. Here’s what I’ve already tried: Setting location permissions to Never in the settings. Stopping startUpdatingLocation(), stopMonitoringSignificantLocationChanges(), and geofencing (using locationManager.stopMonitoringRegions()). Calling locationManager.showsBackgroundLocationIndicator = false. Ensuring that the CLLocationManager is fully invalidated. Despite all of this, the background location indicator still remains in the status bar. I’ve tested it on real devices, as well as in the simulator, with no improvement. Has anyone experienced something similar, or can suggest why this might be happening? Could this be related to an iOS 18+ issue? Any insights or guidance would be greatly appreciated.

I was wondering if anyone had experience with Managed Device Profiles on iPad to be able to answer a quick question regarding passcode reset. We are using Microsoft Intune to manage our fleet of iPads that our store employees will use on an Ad-Hoc basis. When a user logs into an iPad for the day, we are issuing a resetPasscode command to the MicrosoftGraph specifying that device ID. We are getting a successful response to the iPad itself. But the device is allowing the user 1 hour of free time to dismiss the reset passcode dialogue. Which enables them to use the iPad unprotected for up to an hour, which is not what we want. Does anyone know of any way to force the user to select a passcode immediately? I know this is a device side restriction. But is there anything apple can do to help us in this instance, since our MDM profile can't close this time window on the Intune side?

To apply for NFC & SE Platform entitlement, I need to provide information regarding licensed applets and TSM. However, I currently lack background knowledge in these areas. Could you provide me with an overview or examples of what licensed applets and TSM entail?

Hi. We are trying to get the access token before calling any API. The app can go in bad network areas but the token acquisition keeps happening for the network call. The devices are managed devices which means it has some policies installed. We are using MSAL lib for the authentication and we are investigating from that angle too but the below error seems to be coming from apple authentication which needs our attention. ========================================== LaunchServices: store (null) or url (null) was nil: Error Domain=NSOSStatusErrorDomain Code=-54 "process may not map database" UserInfo={NSDebugDescription=process may not map database, _LSLine=68, _LSFunction=_LSServer_GetServerStoreForConnectionWithCompletionHandler} Attempt to map database failed: permission was denied. This attempt will not be retried. Failed to initialize client context with error Error Domain=NSOSStatusErrorDomain Code=-54 "process may not map database" UserInfo={NSDebugDescription=process may not map database, _LSLine=68, _LSFunction=_LSServer_GetServerStoreForConnectionWithCompletionHandler} Failed to get application extension record: Error Domain=NSOSStatusErrorDomain Code=-54 "(null)" ASAuthorizationController credential request failed with error: Error Domain=com.apple.AuthenticationServices.AuthorizationError Code=1003 "(null)" ========================================== This happens mostly when we switches the network or keep the device in no or low network area. This comes sometimes when app goes in background too. Just trying to give as much as information I could. Any lead would be highly appreciated. Thank you

I have configured DKIM and amazon's default spf. but can't get emails using Amazon Send, do I have to configure a custom domain name here for this to work, I'd like to get a definitive conclusion!

Hello! Few month ago i did get hacked on my pc and then my android and iphone. Did get at notice that payments couldent draw. lucky I only had 240kr on lunar card that it did draw 200kr to a gift card. Did get mail from skrill that a account whas created with one of my Gmail’s. Tryed to log them out but window did keep close. Gmail did flag like crazy and wanted me to change pw. how the fuck when I lost control of my phone?!?!??! Just lock it god Damn. let’s make it short! I shared network to pc from my phone With usb. I don’t just think it whas a attacker program as Gmail did flag. I think I did get mirror linked on my android and maybe my iphone. Had a real struggle to reset my pc and phones before it worked. My iPhone drains battery like crazy and feels laggy sometimes. A non registered number whas added to two Gmail’s that they did try to change pw multiple times. did notice I Linux pc activity on my fb and some other stuff. My iphone do reboot still sometimes and every second reboot wifi/bluet can’t be activated and mobile share change pw as the original one did look. Next reboot all work and are the same again. Iam scared that iam still hacked or havent removed him from everything. How can I make sure that Iam still not mirror linked and that he or she can’t access anything? Sorry for the long text but iam scared as fuck.

I am in need of assistance with sandboxing the riot games client and game league of legends. I originally played on a vm from linux but after the change to the incredibly intrusive rootkit malware vanguard. I cannot play from a vm or at least it would be difficult, if this route of containerizing it on mac proves to be more difficult (which wouldn't make sense) then I will go back to spoofing the a vm to not look like a vm. This is even more infuriating because I almost exclusively play Team Fight Tactics in which there is zero cheating and cheating would give a player zero advantage. I decided I would try the Mac version of the game but apple does not sandbox applications at all like flatpak and flatseal from linux. The game has access to my entire system and can read and write to my home directory. This is a massive security risk. I originally tried checking the system settings privacy and security section but the application was not listed anywhere nor was it given access on any of the sections listed. I checked both user local and global tcc.dbs and neither had records that gave the game or client any privileges. This was concerning because tcc.db appears to be the only user facing way of managing permissions that you would think would be a bare minimum baseline and yet the game and client have full access to my system and those permissions are listed nowhere and are given no where. Ie. the default is just to let it do as it pleases even though its a game that only thing it needs to render to the screen. MacOS should properly fix this and implement proper sandboxing of applications like flatpak. I then began building a configuration scheme for sandbox-exec seeing as it was the last opportunity to correctly contain the application to only have the permissions it needs. I carefully crafted the config but it fails just as simply allowing all with allow default... (version 1) (allow default) I run the application with the following command: sandbox-exec -f ~/config.sb "/Users/Shared/Riot Games/Riot Client.app/Contents/MacOS/RiotClientServices" Below are some of the errors produced from running the client sandboxed. 00:44:09.819 (SplashScreenManager) Displaying splash screen from default-splash.html for 2000ms 00:44:09.825 app.isPackaged true 00:44:09.842 Loading page from http://127.0.0.1:51563/index.html sandbox initialization failed: Operation not permitted Failed to initialize sandbox.[0102/004409.953876:ERROR:exception_snapshot_mac.cc(139)] exception_thread not found in task [0102/004409.954838:ERROR:process_reader_mac.cc(309)] thread_get_state(4): (os/kern) invalid argument (4) [0102/004409.954852:ERROR:process_reader_mac.cc(309)] thread_get_state(4): (os/kern) invalid argument (4) [0102/004409.955178:WARNING:process_reader_mac.cc(532)] multiple MH_EXECUTE modules (/usr/libexec/rosetta/runtime, /Library/Apple/usr/libexec/oah/libRosettaRuntime) [0102/004409.955364:WARNING:process_reader_mac.cc(532)] multiple MH_EXECUTE modules (/usr/libexec/rosetta/runtime, /Users/Shared/Riot Games/Riot Client.app/Contents/Frameworks/Riot Client.app/Contents/Frameworks/Riot Client Helper (Renderer).app/Contents/MacOS/Riot Client Helper (Renderer)) [0102/004410.111422:ERROR:exception_snapshot_mac.cc(139)] exception_thread not found in task [4607:0102/004415.168524:ERROR:gpu_process_host.cc(991)] GPU process exited unexpectedly: exit_code=6 [4607:0102/004415.187770:ERROR:network_service_instance_impl.cc(521)] Network service crashed, restarting service. 00:44:15.215 Renderer process has unexpectedly crashed or was killed: crashed (6) { reason: 'crashed', exitCode: 6 }

The Core Problem After Users sign out from the App, the app isn’t properly retrieving the user on second sign in. Instead, it’s treating the user as “Unknown” and saving a new entry in CloudKit and locally. Is there a tutorial aside from 'Juice' that is recent and up to date?

We have 2 developers: Developer A created a Bundle ID and configured Sign in with Apple, but didn't create a corresponding App. This Bundle ID is only used for login on our official website. Developer B created a Bundle ID, configured Sign in with Apple, and has a corresponding App. The issue we're encountering is that because these two Bundle IDs are under different teams, when using the same Apple ID to log into these two applications, different accounts are generated. (We've tested that when creating Service IDs under the same team, logging in with Bundle IDs under the same team generates the same account.) Since Developer A's Bundle ID doesn't have a created app, it cannot be transferred to Developer B. Therefore, we'd like to know if there's any way to make the accounts generated from logging in with the same Apple ID be identical across these two teams?

I am experiencing an issue with Apple Sign-In on Vision Pro. When I build and run the app from Xcode, everything works fine—after signing in, the app returns to the foreground as expected. However, when I launch the app directly on Vision Pro (not from Xcode), after completing the sign-in process, the app does not reopen from the background automatically. Instead, it closes, and I have to manually tap the app icon to reopen it. Has anyone else encountered this issue? Is there a way to ensure the app properly resumes after sign-in without requiring manual intervention?

Hi I am currently developping the "Sign in with apple" feature. We set up everything according to the documentation : https://developer.apple.com/help/account/configure-app-capabilities/configure-private-email-relay-service When trying to send an email from one of the registered communication emails (that is SPF and DKIM Authentication compliant) the emails are still ending up in the spam box. If it can help the received email address (that is hidden) is a gmail. I can not catch what is missing/wrong on our side.

In response to inquiries from users, we have confirmed the following phenomenon. If you select "Private email address" in the flow of new user registration with Apple ID, you will not receive the verification code email when performing two-factor authentication. ■User impact If you use your Apple ID to link an external account without making your email address public, you will not receive the authentication code during two-factor authentication and will not be able to proceed. The date and time of the impact is currently unknown. ◎Impact 1: New registration If you select "Private email address" in the flow of registering a new user with Apple ID, the verification code will not be received during two-factor authentication and registration will not be completed. ◎Impact 2: Login of existing account When two-factor authentication is required for an existing account registered with Apple ID set to "Private email address," the verification code is not received and the user cannot log in. →If you have not registered a login method other than Apple ID for the relevant account, there is no other way to log in. ■About workarounds ・I thought that I could avoid this issue by canceling the private setting of my Apple ID, but I was unable to do so. →There is currently no workaround found for existing users who are experiencing this issue. ・However, the scope of influence is limited. ■Cause investigation status Premise: For an Apple ID whose email address is not made public, the two-factor authentication authentication code email follows the following route. ①CDC/GIGYA miraiz-persol.jp (SendGrid) Apple's email server (relay server to hide the user's real email address) User mailbox →Since '1' are working, the problem seems to have occurred after the connection from ② or ③. (At this stage, we cannot determine who is at fault: the user, MIRAIZ, or Apple. We are currently investigating.) ◎Hypothesis ・Is there something wrong with Apple's mail server? ・Is it not delivered because the user's mailbox is full? ■Questions, research, and responses we would like to receive Please check the following two points and reply. 1st point As shown in the attached image, there seems to be no problem with the SPF settings. Is it possible to check to see if any errors have occurred with Apple's mail server? 2nd point Are there any cases where you still can't receive emails even if you deactivate your Apple ID? I would like to know if there are any patterns in which emails are not being delivered in terms of past inquiries or overall specifications

I'm trying to set up Sign In With Apple on my .NET 7 Web App (Not sure how many people here use this). I followed the guide by Scott Brady here: https://www.scottbrady91.com/openid-connect/implementing-sign-in-with-apple-in-aspnet-core It reaches Apple Sign In OK, authenticates, and passes back to my server, but the callback responds with this error. OpenIdConnectProtocolException: Message contains error: 'invalid_client', error_description: 'error_description is null', error_uri: 'error_uri is null'. Googling hasn't helped much, other than I saw a post saying to wait 48 hours, which I have now done (not that that makes sense anyway). Any idea whats been done wrong? Code below, replacing sensitive data. Startup.cs .AddOpenIdConnect("apple", async options => { options.Authority = "https://appleid.apple.com"; // disco doc: https://appleid.apple.com/.well-known/openid-configuration options.ClientId = "com.rackemapp.applelogin"; // Service ID options.CallbackPath = "/signin-apple"; // corresponding to your redirect URI options.ResponseType = "code id_token"; // hybrid flow due to lack of PKCE support options.ResponseMode = "form_post"; // form post due to prevent PII in the URL options.UsePkce = false; // apple does not currently support PKCE (April 2021) options.DisableTelemetry = true; options.Scope.Clear(); // apple does not support the profile scope options.Scope.Add("openid"); options.Scope.Add("email"); options.Scope.Add("name"); options.Events.OnAuthorizationCodeReceived = context => { context.TokenEndpointRequest.ClientSecret = AppleTokenGenerator.CreateNewToken(); return Task.CompletedTask; }; }); Apple Token Generator public static class AppleTokenGenerator { public static string CreateNewToken() { const string iss = "[MyTeamId]"; // your account's team ID found in the dev portal const string aud = "https://appleid.apple.com"; const string sub = "com.rackemapp.applelogin"; // same as client_id var now = DateTime.UtcNow; // contents of your .p8 file const string privateKey = "[MyKey]"; var ecdsa = ECDsa.Create(); ecdsa?.ImportPkcs8PrivateKey(Convert.FromBase64String(privateKey), out _); var handler = new JsonWebTokenHandler(); return handler.CreateToken(new SecurityTokenDescriptor { Issuer = iss, Audience = aud, Claims = new Dictionary<string, object> { { "sub", sub } }, Expires = now.AddMinutes(5), // expiry can be a maximum of 6 months - generate one per request or re-use until expiration IssuedAt = now, NotBefore = now, SigningCredentials = new SigningCredentials(new ECDsaSecurityKey(ecdsa), SecurityAlgorithms.EcdsaSha256) }); } } Also attached, images of my keys and setp in developer portal

This post is an extension to Importing Cryptographic Keys that covers one specific common case: importing a PEM-based RSA private key and its certificate to form a digital identity. If you have questions or comments, start a new thread in Privacy & Security > General. Tag your thread with Security so that I see it. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" Importing a PEM-based RSA Private Key and its Certificate I regularly see folks struggle to import an RSA private key and its corresponding certificate. Importing Cryptographic Keys outlines various options for importing keys, but in this post I want to cover one specific case, namely, a PEM-based RSA private key and its corresponding certificate. Together these form a digital identity, represented as a SecIdentity object. IMPORTANT If you can repackage your digital identity as a PKCS#12, please do. It’s easy to import that using SecPKCS12Import. If you can switch to an elliptic curve (EC) private key, please do. It’s generally better and Apple CryptoKit has direct support for importing an EC PEM. Assuming that’s not the case, let’s explore how to import a PEM-base RSA private key and its corresponding certificate to form a digital identity. Note The code below was built with Xcode 16.2 and tested on the iOS 18.2 simulator. It uses the helper routines from Calling Security Framework from Swift. This code assumes the data protection keychain. If you’re targeting macOS, add kSecUseDataProtectionKeychain to all the keychain calls. See TN3137 On Mac keychain APIs and implementations for more background to that. Unwrap the PEM To start, you need to get the data out of the PEM: /// Extracts the data from a PEM. /// /// As PEM files can contain a large range of data types, you must supply the /// expected prefix and suffix strings. For example, for a certificate these /// are `"-----BEGIN CERTIFICATE-----` and `-----END CERTIFICATE-----`. /// /// - important: This assumes the simplest possible PEM format. It does not /// handle metadata at the top of the PEM or PEMs with multiple items in them. func dataFromPEM(_ pem: String, _ expectedPrefix: String, _ expectedSuffix: String) -> Data? { let lines = pem.split(separator: "\n") guard let first = lines.first, first == expectedPrefix, let last = lines.last, last == expectedSuffix else { return nil } let base64 = lines.dropFirst().dropLast().joined() guard let data = Data(base64Encoded: base64) else { return nil } return data } IMPORTANT Read the doc comment to learn about some important limitations with this code. Import a Certificate When adding a digital identity to the keychain, it’s best to import the certificate and the key separately and then add them to the keychain. That makes it easier to track down problems you encounter. To import a PEM-based certificate, extract the data from the PEM and call SecCertificateCreateWithData: /// Import a certificate in PEM format. /// /// - important: See ``dataFromPEM(_:_:_:)`` for some important limitations. func importCertificatePEM(_ pem: String) throws -> SecCertificate { guard let data = dataFromPEM(pem, "-----BEGIN CERTIFICATE-----", "-----END CERTIFICATE-----"), let cert = SecCertificateCreateWithData(nil, data as NSData) else { throw NSError(domain: NSOSStatusErrorDomain, code: Int(errSecParam), userInfo: nil) } return cert } Here’s an example that shows this in action: let benjyCertificatePEM = """ -----BEGIN CERTIFICATE----- MIIC4TCCAcmgAwIBAgIBCzANBgkqhkiG9w0BAQsFADAfMRAwDgYDVQQDDAdNb3Vz ZUNBMQswCQYDVQQGEwJHQjAeFw0xOTA5MzAxNDI0NDFaFw0yOTA5MjcxNDI0NDFa MB0xDjAMBgNVBAMMBUJlbmp5MQswCQYDVQQGEwJHQjCCASIwDQYJKoZIhvcNAQEB BQADggEPADCCAQoCggEBAOQe5ai68FQhTVIgpsDK+UOPIrgKzqJcW+wwLnJRp6GV V9EmifJq7wjrXeqmP1XgcNtu7cVhDx+/ONKl/8hscak54HTQrgwE6mK628RThld9 BmZoOjaWWCkoU5bH7ZIYgrKF1tAO5uTAmVJB9v7DQQvKERwjQ10ZbFOW6v8j2gDL esZQbFIC7f/viDXLsPq8dUZuyyb9BXrpEJpXpFDi/wzCV3C1wmtOUrU27xz4gBzi 3o9O6U4QmaF91xxaTk0Ot+/RLI70mR7TYa+u6q7UW/KK9q1+8LeTVs1x24VA5csx HCAQf+xvMoKlocmUxCDBYkTFkmtyhmGRN52XucHgu0kCAwEAAaMqMCgwDgYDVR0P AQH/BAQDAgWgMBYGA1UdJQEB/wQMMAoGCCsGAQUFBwMCMA0GCSqGSIb3DQEBCwUA A4IBAQAyrArH7+IyHTyEOrv/kZr3s3h4HWczSVeiO9qWD03/fVew84J524DiSBK4 mtAy3V/hqXrzrQEbsfyT7ZhQ6EqB/W0flpVYbku10cSVgoeSfjgBJLqgJRZKFonv OQPjTf9HEDo5A1bQdnUF1y6SwdFaY16lH9mZ5B8AI57mduSg90c6Ao1GvtbAciNk W8y4OTQp4drh18hpHegrgTIbuoWwgy8V4MX6W39XhkCUNhrQUUJk3mEfbC/yqfIG YNds0NRI3QCTJCUbuXvDrLEn4iqRfbzq5cbulQBxBCUtLZFFjKE4M42fJh6D6oRR yZSx4Ac3c+xYqTCjf0UdcUGxaxF/ -----END CERTIFICATE----- """ print(try? importCertificatePEM(benjyCertificatePEM)) If you run this it prints: Optional(<cert(0x11e304c10) s: Benjy i: MouseCA>) Import a Private Key To import a PEM-base RSA private key, extract the data from the PEM and call SecKeyCreateWithData: /// Import an 2048-bit RSA private key in PEM format. /// /// Don’t use this code if: /// /// * If you can switch to an EC key.

If you’re starting out with separate private key and certificate PEMs, you have to use SecItemCopyMatching. Note macOS also has SecIdentityCreateWithCertificate, but it has some seriously limitations. First, it’s only available on macOS. Second, it requires the key to be in the keychain. If you’re going to add the key to the keychain anyway, you might as well use SecItemCopyMatching. To form a digital identity from a separate private key and certificate: Add the certificate to the keychain. Add the private key to the keychain. Call SecItemCopyMatching to get back a digital identity. Here’s an example of that in action: /// Imports a digital identity composed of separate certificate and private key PEMs. /// /// - important: See ``dataFromPEM(_:_:_:)`` for some important limitations. /// See ``importRSA2048PrivateKeyPEM(_:)`` for alternative strategies that are /// much easier to deploy. func addRSA2048DigitalIdentityPEMToKeychain(certificate: String, privateKey: String) throws -> SecIdentity { // First import the certificate and private key. This has the advantage in // that it triggers an early failure if the data is in the wrong format. let certificate = try importCertificatePEM(certificate) let privateKey = try importRSA2048PrivateKeyPEM(privateKey) // Check that the private key matches the public key in the certificate. If // not, someone has given you bogus credentials. let certificatePublicKey = try secCall { SecCertificateCopyKey(certificate) } let publicKey = try secCall { SecKeyCopyPublicKey(privateKey) } guard CFEqual(certificatePublicKey, publicKey) else { throw NSError(domain: NSOSStatusErrorDomain, code: Int(errSecPublicKeyInconsistent)) } // Add the certificate first. If that fails — and the most likely error is // `errSecDuplicateItem` — we want to stop immediately. try secCall { SecItemAdd([ kSecValueRef: certificate, ] as NSDictionary, nil) } // The add the private key. do { try secCall { SecItemAdd([ kSecValueRef: privateKey, ] as NSDictionary, nil) } } catch let error as NSError { // We ignore a `errSecDuplicateItem` error when adding the key. It’s // possible to have multiple digital identities that share the same key, // so if you try to add the key and it’s already in the keychain then // that’s fine. guard error.domain == NSOSStatusErrorDomain, error.code == errSecDuplicateItem else { throw error } } // Finally, search for the resulting identity. // // I originally tried querying for the identity based on the certificate’s // attributes — the ones that contribute to uniqueness, namely // `kSecAttrCertificateType`, `kSecAttrIssuer`, and `kSecAttrSerialNumber` — // but that failed for reasons I don't fully understand (r. 144152660). So // now I get all digital identities and find the one with our certificate. let identities = try secCall { SecItemCopyMatching([ kSecClass: kSecClassIdentity, kSecMatchLimit: kSecMatchLimitAll, kSecReturnRef: true, ] as NSDictionary, $0) } as! [SecIdentity] let identityQ = try identities.first { i in try secCall { SecIdentityCopyCertificate(i, $0) } == certificate } return try secCall(Int(errSecItemNotFound)) { identityQ } } IMPORTANT This code is quite subtle.

hello. I am using the app with webview. When I log in to Apple, a typeerror appears. How can I solve this?
