Hey everyone, I'm working on a password manager app for iOS and I'm trying to implement the new iOS 18 feature that lets users enable autofill directly from within the app. I know this exists because I've seen it in action in another app. They've clearly figured it out, but I'm struggling to find any documentation or info about the specific API. Has anyone else had any luck finding this? Any help would be greatly appreciated! Thanks in advance!

Hi everyone, I’m working on an iOS app that uses biometric authentication to access secure keychain items and private keys stored in the Secure Enclave with some data encryption/decryption with those keys. My goal is to minimize the number of biometric prompts by reusing the authentication result within a short time window. I have the following setup: When writing the biometry-restricted keychain items and Secure Enclave keys, I use LAContext with the property LATouchIDAuthenticationMaximumAllowableReuseDuration = 1 minute, and I pass this context as the kSecUseAuthenticationContext field in the query. When retrieving these items later (in a synchronous sequence upon app launch), I pass the same instance of LAContext as the kSecUseAuthenticationContext field. The issue: If I unlock my device and the biometric reuse time has not expired (i.e., less than 1 minute), the first two actions (keychain item retrieval and Secure Enclave key retrieval) do not prompt for Face ID. However, when I attempt to decrypt data with the private key using SecKeyCreateDecryptedData, I’m prompted for Face ID even if the biometric reuse time is still valid. If the biometric reuse time has expired (more than 1 minute since last authentication), I get prompted for Face ID on the first action (keychain retrieval), and subsequent actions (including data decryption) reuse that biometric result. Question: Does this behavior mean that SecKeyCreateDecryptedData ignore the LATouchIDAuthenticationMaximumAllowableReuseDuration property of LAContext, causing an additional biometric prompt during decryption with the private key? Or is there another reason for this behavior? Is there a way to make the biometric result reusable across all these actions, including decryption? Thank you!

I'm using Secure Enclave to generate and use a private key like this: let access = SecAccessControlCreateWithFlags(nil, kSecAttrAccessibleWhenUnlockedThisDeviceOnly, [.privateKeyUsage, .biometryAny], nil) let attributes: [String: Any] = [ kSecAttrKeyType as String: kSecAttrKeyTypeECSECPrimeRandom, kSecAttrKeySizeInBits as String: 256, kSecAttrTokenID as String: kSecAttrTokenIDSecureEnclave, kSecAttrAccessControl as String: access as Any, kSecAttrApplicationTag as String: "com.example.key".data(using: .utf8)!, kSecReturnRef as String: true ] let privateKey = SecKeyCreateRandomKey(attributes as CFDictionary, nil) Later, I use this key to sign a message: let signature = SecKeyCreateSignature(privateKey, .ecdsaSignatureMessageX962SHA256, dataToSign as CFData, nil) This prompts for biometric authentication, but shows the default system text. How can I customize or localize the biometric prompt (e.g., title, description, button text) shown during SecKeyCreateSignature? Thanks!

Regarding the issue of login controls remaining on screen for a few seconds when using a subclass of SFAuthorizationPluginView, I wanted to inquire whether any progress has been made on resolving it. To recap, per notes I found in the QAuthPlugins sample code: Due to a bug (FB12074874), the use of an SFAuthorizationPluginView subclass can cause the login controls to remain onscreen for a significant amount of time (roughly 5 seconds) after login is complete, resulting in them being onscreen at the same time as the Finder’s menu bar and the Dock. The exact circumstances under which this happens are not well understood, but one factor seems to be running on a laptop where the main display is mirrored to an external display. Specifically, I would like to know: If there any other information about how the issue is reproduced? For my part I can say that it reproduces with out the use of a mirrored display. So far it reproduces for all of our developers and testers, all of the time. Are there any known workarounds? Is there any expectation that this issue will be addressed? Thank you so much!

In my app, I use SecItem to store some data in the Keychain. I’d like to know — when a user sets up a new iPhone and transfers data from the old device, will those Keychain items be migrated or synced to the new device?

I am working on adding RFC4217 Secure FTP with TLS by extending Mike Gleason's classic libncftp client library. I refactored the code to include an FTP channel abstraction with FTP channel abstraction types for TCP, TLS, and TCP with Opportunistic TLS types. The first implementation of those included BSD sockets that libncftp has always supported with the clear TCP channel type. I first embarked on extending the sockets implementation by adding TCP, TLS, and TCP with Opportunistic TLS channel abstraction types against the new, modern Network.framework C-based APIs, including using the “tricky” framer technique to employ a TCP with Opportunistic TLS FTP channel abstraction type to support explicit FTPS as specified by RFC4217 where you have to connect first in the clear with TCP, request AUTH TLS, and then start TLS after receiving positive confirmation. That all worked great. Unfortunately, at the end of that effort, I discovered that many modern FTPS server implementations (vsftpd, pure-ftpd, proftpd) mandate TLS session reuse / resumption across the control and data channels, specifying the identical session ID and cipher suites across the control and data channels. Since Network.framework lacked a necessary and equivalent to the Secure Transport SSLSetPeerID, I retrenched and rewrote the necessary TLS and TCP with Opportunistic TLS FTP channel abstraction types using the now-deprecated Secure Transport APIs atop the Network.framework-based TCP clear FTP channel type abstraction I had just written. Using the canonical test server I had been using throughout development, test.rebex.net, this Secure Transport solution seemed to work perfectly, working in clear, secure-control-only, and secure-control+data explicit FTPS operation. I then proceeded to expand testing to include a broad set of Microsoft FTP Service, pure-ftpd, vsftpd, proftpd, and other FTP servers identified on the Internet (a subset from this list: https://gist.github.com/mnjstwins/85ac8348d6faeb32b25908d447943300). In doing that testing, beyond test.rebex.net, I was unable to identify a single (among hundreds), that successfully work with secure-control+data explicit FTPS operation even though nearly all of them work with secure-control-only explicit FTPS operation. So, I started regressing my libncftp + Network.framework + Secure Transport implementation against curl 8.7.1 on macOS 14.7.2 “Sonoma": % which curl; `which curl` --version /usr/bin/curl curl 8.7.1 (x86_64-apple-darwin23.0) libcurl/8.7.1 (SecureTransport) LibreSSL/3.3.6 zlib/1.2.12 nghttp2/1.61.0 Release-Date: 2024-03-27 Protocols: dict file ftp ftps gopher gophers http https imap imaps ipfs ipns ldap ldaps mqtt pop3 pop3s rtsp smb smbs smtp smtps telnet tftp Features: alt-svc AsynchDNS GSS-API HSTS HTTP2 HTTPS-proxy IPv6 Kerberos Largefile libz MultiSSL NTLM SPNEGO SSL threadsafe UnixSockets I find that curl (also apparently written against Secure Transport) works in almost all of the cases my libncftp does not. This is a representative example: % ./samples/misc/ncftpgetbytes -d stderr --secure --explicit --secure-both ftps://ftp.sjtu.edu.cn:21/pub/README.NetInstall which fails in the secure-control+data case with errSSLClosedAbort on the data channel TLS handshake, just after ClientHello, attempts whereas: % curl -4 --verbose --ftp-pasv --ftp-ssl-reqd ftp://ftp.sjtu.edu.cn:21/pub/README.NetInstall succeeds. I took an in-depth look at the implementation of github.com/apple-oss-distributions/curl/ and git/github.com/apple-oss-distributions/Security/ to identify areas where my implementation was, perhaps, deficient relative to curl and its curl/lib/vtls/sectransp.c Secure Transport implementation. As far as I can tell, I am doing everything consistently with what the Apple OSS implementation of curl is doing. The analysis included: SSLSetALPNProtocols Not applicable for FTP; only used for HTTP/2 and HTTP/3. SSLSetCertificate Should only be relevant when a custom, non-Keychain-based certificate is used. SSLSetEnabledCiphers This could be an issue; however, the cipher suite used for the data channel should be the same as that used for the control channel. curl talks about disabling "weak" cipher suites that are known-insecure even though the default suites macOS enables are unlikely to enable them. SSLSetProtocolVersionEnabled We do not appear to be getting a protocol version negotiation error, so this seems unlikely, but possible. SSLSetProtocolVersionMax We do not appear to be getting a protocol version negotiation error, so this seems unlikely, but possible. SSLSetProtocolVersionMin We do not appear to be getting a protocol version negotiation error, so this seems unlikely, but possible. SSLSetSessionOption( , kSSLSessionOptionFalseStart) curl does seem to enable this for certain versions of macOS and disables it for others. Possible. Running curl with the --false-start option does not seem to make a difference. SSLSetSessionOption( , kSSLSessionOptionSendOneByteRecord) Corresponds to "*****" which seems defaulted and is related to an SSL security flaw when using CBC-based block encryption ciphers, which is not applicable here. Based on that, further experiments I attempted included: Disable use of kSSLSessionOptionBreakOnServerAuth: No impact Assert use of kSSLSessionOptionFalseStart: No impact Assert use of kSSLSessionOptionSendOneByteRecord: No impact Use SSLSetProtocolVersionMin and SSLSetProtocolVersionMax in various combinations: No impact Use SSLSetProtocolVersionEnabled in various combinations: No impact Forcibly set a single cipher suite (TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, known to work with a given server): No impact Employ a SetDefaultCipherSuites function similar to what curl does (filtering out “weak” cipher suites): No impact Notably, I can never coax a similar set of cipher suites that macOS curl does with that technique. In fact, it publishes ciphers that aren’t even in <Security/CipherSuite.h> nor referenced by github.com/apple-oss-distributions/curl/curl/lib/vtls/sectransp.c. Assert use of kSSLSessionOptionAllowRenegotiation: No impact Assert use of kSSLSessionOptionEnableSessionTickets: No impact Looking at Wireshark, my ClientHello includes status_request, signed_certificate_timestamp, and extended_master_secret extensions whereas macOS curl's never do--same Secure Transport APIs. None of the above API experiments seem to influence the inclusion / exclusion of those three ClientHello additions. Any suggestions are welcomed that might shine a light on what native curl has access to that allows it to work with ST for these FTP secure-control+data use cases.

I have 2 basic questions related to Launch Constraints: [Q1] Are Launch Constraints supposed to work when SIP is disabled? From what I'm observing, when SIP is disabled, Launch Constraints (e.g. Launch Constraint Parent Process) are not enforced. I can understand that. But it's a bit confusing considering that the stack diagram in the WWDC 2023 session is placing the 'Environment Constraints' block under SIP, not above. Also the documentation only mentions SIP for the 'is-sip-protected' fact. [Q2] Is the SpawnConstraint key in legacy launchd plist files (i.e. inside /Library/Launch(Agents|Daemons)) officially supported? From what I'm seeing, it seems to be working when SIP is enabled. But the WWDC session and the documentation don't really talk about this case.

Issue Summary I'm encountering a DCError.invalidInput error when calling DCAppAttestService.shared.generateAssertion() in my App Attest implementation. This issue affects only a small subset of users - the majority of users can successfully complete both attestation and assertion flows without any issues. According to Apple Engineer feedback, there might be a small implementation issue in my code. Key Observations Success Rate: ~95% of users complete the flow successfully Failure Pattern: The remaining ~5% consistently fail at assertion generation Key Length: Logs show key length of 44 characters for both successful and failing cases Consistency: Users who experience the error tend to experience it consistently Platform: Issue observed across different iOS versions and device types Environment iOS App Attest implementation Using DCAppAttestService for both attestation and assertion Custom relying party server communication Issue affects ~5% of users consistently Key Implementation Details 1. Attestation Flow (Working) The attestation process works correctly: // Generate key and attest (successful for all users) self.attestService.generateKey { keyId, keyIdError in guard keyIdError == nil, let keyId = keyId else { return completionHandler(.failure(.dcError(keyIdError as! DCError))) } // Note: keyId length is consistently 44 characters for both successful and failing users // Attest key with Apple servers self.attestKey(keyId, clientData: clientData) { result in // ... verification with RP server // Key is successfully stored for ALL users (including those who later fail at assertion) } } 2. Assertion Flow (Failing for ~5% of Users with invalidInput) The assertion generation fails for a consistent subset of users: // Get assertion data from RP server self.assertRelyingParty.getAssertionData(kid, with: data) { result in switch result { case .success(let receivedData): let session = receivedData.session let clientData = receivedData.clientData let hash = clientData.toSHA256() // SHA256 hash of client data // THIS CALL FAILS WITH invalidInput for ~5% of users // Same keyId (44 chars) that worked for attestation self.attestService.generateAssertion(kid, clientDataHash: hash) { assertion, err in guard err == nil, let assertion = assertion else { // Error: DCError.invalidInput if let err = err as? DCError, err.code == .invalidKey { return reattestAndAssert(.invalidKey, completionHandler) } else { return completionHandler(.failure(.dcError(err as! DCError))) } } // ... verification logic } } } 3. Client Data Structure Client data JSON structure (identical for successful and failing users): // For attestation (works for all users) let clientData = ["challenge": receivedData.challenge] // For assertion (fails for ~5% of users with same structure) var clientData = ["challenge": receivedData.challenge] if let data = data { // Additional data for assertion clientData["account"] = data["account"] clientData["amount"] = data["amount"] } 4. SHA256 Hash Implementation extension Data { public func toSHA256() -> Data { return Data(SHA256.hash(data: self)) } } 5. Key Storage Implementation Using UserDefaults for key storage (works consistently for all users): private let keyStorageTag = "app-attest-keyid" func setKey(_ keyId: String) -> Result<(), KeyStorageError> { UserDefaults.standard.set(keyId, forKey: keyStorageTag) return .success(()) } func getKey() -> Result<String?, KeyStorageError> { let keyId = UserDefaults.standard.string(forKey: keyStorageTag) return .success(keyId) } Questions User-Specific Factors: Since this affects only ~5% of users consistently, could there be device-specific, iOS version-specific, or account-specific factors that cause invalidInput? Key State Validation: Is there any way to validate the state of an attested key before calling generateAssertion()? The key length (44 chars) appears normal for both successful and failing cases. Keychain vs UserDefaults: Could the issue be related to using UserDefaults instead of Keychain for key storage? Though this works for 95% of users. Race Conditions: Could there be subtle race conditions or timing issues that only affect certain users/devices? Error Recovery: Is there a recommended way to handle this error? Should we attempt re-attestation for these users? Additional Context & Debugging Attempts Consistent Failure: Users who experience this error typically experience it on every attempt Key Validation: Both successful and failing users have identical key formats (44 character strings) Device Diversity: Issue observed across different device models and iOS versions Server Logs: Our server successfully provides challenges and processes attestation for all users Re-attestation: Forcing re-attestation sometimes resolves the issue temporarily, but it often recurs The fact that 95% of users succeed with identical code suggests there might be some environmental or device-specific factor that we're not accounting for. Any insights into what could cause invalidInput for a subset of users would be invaluable.

I have developed a sample app following the example found Updating your app package installer to use the new Service Management API and referring this discussion on XPC Security. The app is working fine, I have used Swift NSXPCConnection in favour of xpc_connection_create_mach_service used in the example. (I am running app directly from Xcode) I am trying to set up security requirements for the client connection using setCodeSigningRequirement on the connection instance. But it fails for even basic requirement connection.setCodeSigningRequirement("anchor apple"). Error is as follows. cannot open file at line 46986 of [554764a6e7] os_unix.c:46986: (0) open(/private/var/db/DetachedSignatures) - Undefined error: 0 xpc_support_check_token: anchor apple error: Error Domain=NSOSStatusErrorDomain Code=-67050 "(null)" status: -67050 I have used codesign -d --verbose=4 /path/to/executable to check the attributes I do get them in the terminal.

Q: Please advise is there some setting required to be enabled or I have to sign code with some flags enabled. Note: My app is not running in a Sandbox or Hardened Runtime, which I want.

Hello! We have code that extracts macOS Installer package (.pkg, .mpkg) signature information using APIs defined in <xar/xar.h> The code opens the package using ‘xar_open’ API like this. func open(file: String) throws(XarError) { xarfile = xar_open(file, READ) if xarfile == nil { throw .fileOpenError } } This code produces a clang warning in our CI build system when built for macOS 12 and up. 'xar_open' was deprecated in macOS 12.0: xar is a deprecated file format and should not be used. Question #1: What is the appropriate / more preferred way to extract signature information from an Installer package given that xar related APIs are deprecated? We use xar APIs to validate the package signature prior to installation to prevent packagers not signed by our team ID from being installed. Question #2: “xar is a deprecated file format and should not be used.”. Does this phrase refer to the file format that should be avoided or the API that extract signature information? We distribute our product using Developer ID method that using pkg/mpkg formats which I believe internally follow the same structure as xar files. I hope this message does not mean we should rethink the distribution method for our products. Thank you. Filed FB FB17148233 as well.

Hi, We are using the following API from sys/random.h to generate entropy in our module. int getentropy(void* buffer, size_t size); Could you confirm if this API internally uses a non-physical entropy source and adhere to SP800-90B as the following document says: https://csrc.nist.gov/CSRC/media/projects/cryptographic-module-validation-program/documents/entropy/E181_PublicUse.pdf

Hello, I have a password manager app and have noticed a new feature in AutoFill &amp; Passwords called "Set Up Codes In". I see that my competitors have been able to implement this feature but cannot find any documentation on how to do this. How can I make it so my app can support this feature. Any help to pointing me to the documentation or otherwise would be greatly appreciated. Thanks! //Ray

Hello, I have a password manager app and would like to help my user's to enable the Safari autofill capability. I've made the password credential extension and that is working great. I just need to help my user's enable the feature. I could point them to Settings-&gt;General-&gt;AutoFill &amp; Password and instruct them to turn the feature on. However, I've noticed that my competitors are able to present an alert directly from their app to turn the feature on (without going to settings at all). I can't find any documentation on how to do this? Thanks for your help! //Ray

My high-level goal is to add support for Game Mode in a Java game, which launches via a macOS "launcher" app that runs the actual java game as a separate process (e.g. using the java command line tool). I asked this over in the Graphics & Games section and was told this, which is why I'm reposting this here. I'm uncertain how to speak to CLI tools and Java games launched from a macOS app. These sound like security and sandboxing questions which we recommend you ask about in those sections of the forums. The system seems to decide whether to enable Game Mode based on values in the Info.plist (e.g. for LSApplicationCategoryType and GCSupportsGameMode). However, the child process can't seem to see these values. Is there a way to change that? (The rest of this post is copied from my other forums post to provide additional context.) Imagine a native macOS app that acts as a "launcher" for a Java game.** For example, the "launcher" app might use the Swift Process API or a similar method to run the java command line tool (lets assume the user has installed Java themselves) to run the game. I have seen How to Enable Game Mode. If the native launcher app's Info.plist has the following keys set: LSApplicationCategoryType set to public.app-category.games LSSupportsGameMode set to true (for macOS 26+) GCSupportsGameMode set to true The launcher itself can cause Game Mode to activate if the launcher is fullscreened. However, if the launcher opens a Java process that opens a window, then the Java window is fullscreened, Game Mode doesn't seem to activate. In this case activating Game Mode for the launcher itself is unnecessary, but you'd expect Game Mode to activate when the actual game in the Java window is fullscreened. Is there a way to get Game Mode to activate in the latter case? ** The concrete case I'm thinking of is a third-party Minecraft Java Edition launcher, but the issue can also be demonstrated in a sample project (FB13786152). It seems like the official Minecraft launcher is able to do this, though it's not clear how. (Is its bundle identifier hardcoded in the OS to allow for this? Changing a sample app's bundle identifier to be the same as the official Minecraft launcher gets the behavior I want, but obviously this is not a practical solution.)

Hello, I'm seeking some clarification regarding the use of accessibility and input monitoring APIs in sandboxed apps that are distributed through the App Store. I understand that accessibility permissions are generally restricted for App Store apps. However, I've seen several recently released apps request these permissions directly upon first launch. I'm aware that apps submitted prior to 2012 may have legacy access to certain APIs, but the ones I'm referring to appear to be recent - within the past year. While it's possible these apps were approved despite the restrictions, I want to make sure I'm not overlooking something. I also came across a recent discussion on this topic, and one post in particular stood out: Link I’d really appreciate some clarification on what's officially allowed. Specifically: Are accessibility permissions ever allowed? If so, under what circumstances? Is input monitoring permitted for apps on the App Store? (The referenced post says yes, but since it's from 2022, I just want to confirm) The linked post suggests that event generation might be allowed on the App Store, though the author hadn’t explored that privilege in detail and recommended opening a DTS tech support incident. I’ve done that and have a support case open - would it be possible to take a closer look at this? For context, my app (currently distributed outside the App Store) uses CGEventPost and CGEventCreateMouseEvent to modify mouse behavior. Thank you

Hi Team, How can we fetch the macOS password requirement(for setting a new password) that are inforce during login for users? Is there a way to get this info in swift programming?

What Has Been Implemented Replaced the default loginwindow:login with a custom authorization plugin. The plugin: Performs primary OTP authentication. Displays a custom password prompt. Validates the password using Open Directory (OD) APIs. Next Scenario was handling password change Password change is simulated via: sudo pwpolicy -u robo -setpolicy "newPasswordRequired=1" On next login: Plugin retrieves the old password. OD API returns kODErrorCredentialsPasswordChangeRequired. Triggers a custom change password window to collect and set new password. Issue Observed : After changing password: The user’s login keychain resets. Custom entries under the login keychain are removed. We have tried few solutions Using API, SecKeychainChangePassword(...) Using CLI, security set-keychain-password -o oldpwd -p newpwd ~/Library/Keychains/login.keychain-db These approaches appear to successfully change the keychain password, but: On launching Keychain Access, two password prompts appear, after authentication, Keychain Access window doesn't appear (no app visibility). Question: Is there a reliable way (API or CLI) to reset or update the user’s login keychain password from within the custom authorization plugin, so: The keychain is not reset or lost. Keychain Access works normally post-login. The password update experience is seamless. Thank you for your help and I appreciate your time and consideration

In the hopes of saving others time, the updated demo project (i.e. the new Shiny) can be found from the video 'Resources' section under 'Performing fast account creation with passkeys'. The beta documentation can also be found from there. All of the new functionality is available only on *OS 26 at this time.

Trying to apply 'always trust' to certificate added to keychain using both SecItemAdd() and SecPKCS12Import() with SecTrustSettingsSetTrustSettings(). I created a launchdaemon for this purpose. AuthorizationDB is modified so that any process running in root can apply trust to certificate. let option = SecTrustSettingsResult.trustRoot.rawValue // SecTrustSettingsResult.trustAsRoot.rawValue for non-root certificates let status = SecTrustSettingsSetTrustSettings(secCertificate, SecTrustSettingsDomain.admin, [kSecTrustSettingsResult: NSNumber(value: option.rawValue)] as CFTypeRef). Above code is used to trust certificates and it was working on os upto 14.7.4. In 14.7.5 SecTrustSettingsSetTrustSettings() returns errAuthorizationInteractionNotAllowed. In 15.5 modifying authorization db with AuthorizationRightSet() itself is returning errAuthorizationDenied.Tried manually editing authorization db via terminal and same error occurred. Did apple update anything on Security framework? Any other way to trust certificates?

Hi, We use the iOS Keychain in our mobile app to securely store and retrieve data, which is tightly coupled with the initialization of some app features within the application. This issue is encountered during app launch We retrieve during Splash Screen UI controller at viewDidApper() The logic we use to access the Keychain is as follows: NSDate *NSDate_CD; NSString *account = [NSString stringWithUTF8String:@"SOME_KEY_ACCOUNT"]; NSString *attrgen = [NSString stringWithUTF8String:@"SOME_KEY"]; NSMutableDictionary *query = [[NSMutableDictionary alloc] init]; [query setObject:(__bridge id)(kSecClassGenericPassword) forKey:(__bridge id&lt;NSCopying&gt;)(kSecClass)]; [query setObject:attrgen forKey:(__bridge id&lt;NSCopying&gt;)(kSecAttrGeneric)]; [query setObject:(__bridge id)(kSecAttrAccessibleAfterFirstUnlockThisDeviceOnly) forKey:(__bridge id&lt;NSCopying&gt;)(kSecAttrAccessible)]; [query setObject: [NSBundle mainBundle].bundleIdentifier forKey:(__bridge id&lt;NSCopying&gt;)(kSecAttrService)]; [query setObject:account forKey:(__bridge id&lt;NSCopying&gt;)(kSecAttrAccount)]; [query setObject:@YES forKey:(__bridge id&lt;NSCopying&gt;)(kSecReturnAttributes)]; [query setObject:@YES forKey:(__bridge id&lt;NSCopying&gt;)(kSecReturnData)]; CFDictionaryRef valueAttributes = NULL; OSStatus status = SecItemCopyMatching((__bridge CFDictionaryRef)query, (CFTypeRef *)&amp;valueAttributes); NSDictionary *attributes = (__bridge_transfer NSDictionary *)valueAttributes; if(status==errSecSuccess) { NSDate_CD = [attributes objectForKey:(__bridge id)kSecAttrCreationDate]; } else { NSLog(@"Key chain query failed"); } However, some users have reported intermittent failures during app launch. Upon investigation, we discovered that these failures are caused by exceptions thrown by the iOS Keychain, which the app is currently not handling. Unfortunately, we do not log the exception or the Keychain error code in the app logs at the moment, but we plan to implement this logging feature in the near future. For now, we are trying to better understand the nature of these errors. Could you help clarify the following Keychain errors, which might be encountered from the code above? errSecServiceNotAvailable (-25307) errSecAllocate (-108) errSecNotAvailable (-25291) If these errors are encountered, are they typically persistent or are they temporary states that could resolve on their own? Your insights would be greatly appreciated. Thank you.
