DeviceCheck Framework Crash: DCAnalytics nil Dictionary Insertion in Production
We're experiencing crashes in our production iOS app related to Apple's DeviceCheck framework. The crash occurs in DCAnalytics internal performance tracking, affecting some specific versions of iOS 18 (18.4.1, 18.5.0). Crash Signature CoreFoundation: -[__NSDictionaryM setObject:forKeyedSubscript:] + 460 DeviceCheck: -[DCAnalytics sendPerformanceForCategory:eventType:] + 236 Observed Patterns Scenario 1 - Token Generation: Crashed: com.appQueue EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000010 DeviceCheck: -[DCDevice generateTokenWithCompletionHandler:] Thread: Background dispatch queue Scenario 2 - Support Check: Crashed: com.apple.main-thread EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000008 DeviceCheck: -[DCDevice _isSupportedReturningError:] DeviceCheck: -[DCDevice isSupported] Thread: Main thread Root Cause Analysis The DCAnalytics component within DeviceCheck attempts to insert a nil value into an NSMutableDictionary when recording performance metrics, indicating missing nil validation before dictionary operations. Reproduction Context Crashes occur during standard DeviceCheck API usage: Calling DCDevice.isSupported property Calling DCDevice.generateToken(completionHandler:) (triggered by Firebase App Check SDK) Both operations invoke internal analytics that fail with nil insertion attempts. Concurrency Considerations We've implemented sequential access guards around DeviceCheck token generation to prevent race conditions, yet crashes persist. This suggests the issue likely originates within the DeviceCheck framework's internal implementation rather than concurrent access from our application code. Note: Scenario 2 occurs through Firebase SDK's App Check integration, which internally uses DeviceCheck for attestation. Request Can Apple engineering confirm if this is a known issue with DeviceCheck's analytics subsystem? Is there a recommended workaround to disable DCAnalytics or ensure thread-safe DeviceCheck API usage? Any guidance on preventing these crashes would be appreciated.

CryptoKitError
Hi, I am using CryptoKit in my app. I am getting an error sometimes with some users. I log the description to Firebase but I am not sure what is it exactly about.  CryptoKit.CryptoKitError error 2  CryptoKit.CryptoKitError error 3 I receive both of these errors. I also save debug prints to a log file and let users share them with me. Logs are line-by-line encrypted but after getting these errors in the app also decryption of log files doesn't work and it throws these errors too. I couldn't reproduce the same error by myself, and I can't reach the user's logs so I am a little blind about what triggers this. It would be helpful to understand what these errors mean. Thanks

Why won't my AutoFill Credential Provider show up in the context menu of a generic textfield?
I noticed, that even though my AutoFill Credential Provider Extension works with Safari for both Passwords and Passkeys, it doesn't work in context menus inside arbitrary textfields, meanwhile the same is true for the Apple Passwords app. This is a great hit to AutoFill productivity, as my extension is unable to fill textfields by just going to the context menu and clicking AutoFill > Passwords.. Is this a feature only available to Apple via private APIs, or is this something I can interface with? I checked and the Passwords app does use some undocumented but non-private entitlements: [Key] com.apple.authentication-services.access-credential-identities [Value] [Bool] true I also checked the responsible executable for some hints (AutoFillPanelService) however found nothing that would lead me to believe this is a public extension point. Another idea I had was trying to use a macOS Service for this, however Services in the "General" category won't show up in any context menu, only in the Application's Main Menu.

C++ HMAC-SHA256 Signature Works in Python, Fails in C++ — Possible Xcode Runtime Issue?
Hi all, I’m building a macOS-native C++ trading bot, compiled via Xcode. It sends REST API requests to a crypto exchange (Bitvavo) that require HMAC-SHA256 signatures using a pre-sign string (timestamp + method + path + body) and an API secret. Here’s the issue: • The exact same pre-sign string and API secret produce valid responses when signed using Python (hmac.new(secret, msg, hashlib.sha256)), • But when I generate the HMAC signature using C++ (HMAC(EVP_sha256, ...) via OpenSSL), the exchange returns an invalid signature error. Environment: • Xcode 15.3 / macOS 14.x • OpenSSL installed via Homebrew • HMAC test vectors match Python’s output for basic strings (so HMAC lib seems correct) Yet when using the real API keys and dynamic timestamped messages, something differs enough to break verification — possibly due to UTF-8 encoding, memory alignment, or newline handling differences in the Xcode C++ runtime? Has anyone experienced subtle differences between Python and C++ HMAC-SHA256 behavior when compiled in Xcode? I’ve published a GitHub repo for reproducibility: 🔗 https://github.com/vanBaardewijk/bitvavo-cpp-signature-test Thanks in advance for any suggestions or insights. Sascha

Auth Plugin Timeout Issue During Screen Unlock
Hi! We are developing an authentication plugin for macOS that integrates with the system's authentication flow. The plugin is designed to prompt the user for approval via a push notification in our app before allowing access. The plugin is added as the first mechanism in the authenticate rule, followed by the default builtin:authenticate as a fallback. When the system requests authentication (e.g., during screen unlock), our plugin successfully displays the custom UI and sends a push notification to the user's device. However, I've encountered the following issue: If the user does not approve the push notification within ~30 seconds, the system resets the screen lock (expected behavior). If the user approves the push notification within approximately 30 seconds but doesn’t start entering their password before the timeout expires, the system still resets the screen lock before they can enter their password, effectively canceling the session. What I've Tried: Attempted to imitate mouse movement after the push button was clicked to keep the session active. Created a display sleep prevention assertion using IOKit to prevent the screen from turning off. Used the caffeinate command to keep the display and system awake. Tried setting the result as allow for the authorization request and passing an empty password to prevent the display from turning off. I also checked the system logs when this issue occurred and found the following messages: ___loginwindow: -[LWScreenLock (Private) askForPasswordSecAgent] | localUser = >timeout loginwindow: -[LWScreenLock handleUnlockResult:] _block_invoke | ERROR: Unexpected _lockRequestedBy of:7 sleeping screen loginwindow: SleepDisplay | enter powerd: Process (loginwindow) is requesting display idle___ These messages suggest that the loginwindow process encounters a timeout condition, followed by the display entering sleep mode. Despite my attempts to prevent this behavior, the screen lock still resets prematurely. Questions: Is there a documented (or undocumented) system timeout for the entire authentication flow during screen unlock that I cannot override? Are there any strategies for pausing or extending the authentication timeout to allow for complex authentication flows like push notifications? Any guidance or insights would be greatly appreciated. Thank you!

Help with Passkey Registration & Authentication on iOS 17 (Credential Provider + Error Code 1004)
I’m implementing passkey registration and authentication in an iOS 17 app with a credential provider extension, but I’m running into an issue. Setup: I have a credential provider target configured. The app correctly shows the pop-up to register the passkey with my app. My Info.plist is set up properly. Issue: When the following function is triggered: override func prepareInterface(forPasskeyRegistration registrationRequest: ASCredentialRequest) { "code to generate registrationRequest..." let controller = ASAuthorizationController(authorizationRequests: [registrationRequest]) controller.delegate = self controller.presentationContextProvider = self controller.performRequests() } I get the following error: Domain=com.apple.AuthenticationServices.AuthorizationError Code=1004 I do not own the relying party domain (e.g., https://webauthn.io), so I cannot configure an apple-app-site-association file on the website. Question: How can I register and authenticate passkeys on any site that allows passkeys (such as webauthn.io) when I don’t control the webpage? Are there any workarounds or best practices for handling this in iOS 17? Any insights would be greatly appreciated!

deviceOwnerAuthenticationWithCompanion evaluation not working as expected
In one of my apps I would like to find out if users have their device set up to authenticate with their Apple Watch. According to the documentation (https://developer.apple.com/documentation/localauthentication/lapolicy/deviceownerauthenticationwithcompanion) this would be done by evaluating the LAPolicy like this: var error: NSError? var canEvaluateCompanion = false if #available(iOS 18.0, *) { canEvaluateCompanion = context.canEvaluatePolicy(.deviceOwnerAuthenticationWithCompanion, error: &error) } But when I run this on my iPhone 16 Pro (iOS 18.5) with a paired Apple Watch SE 2nd Gen (watchOS 11.5) it always returns false and the error is -1000 "No companion device available". But authentication with my watch is definitely enabled, because I regularly unlock my phone with the watch. Other evaluations of using biometrics just works as expected. Anything that I am missing?

Yubikey Authentication iPad/iOS26
Hey all, Question for the masses.... Does the Yubikey authentication have a OS dependency and it only works with a stable, public OS? Does Azure/Okta/Yubikey beta OS26? My CEO installed iPadOS 26 on his iPad and was not able to authenticate via Yubikey into our company environment. I ran the same scenario on my iPad using iPadOS 26 and I had the same results. Downgrading to iPAdOS doesn't pose these issues. I'm assuming something isn't fine-tuned yet?

App Attest Suddenly Failing in Production — Error 4 (serverUnavailable)
Hi Apple Team and Community, We've encountered a sudden and widespread failure with the App Attest service starting today across multiple production apps and regions. The previously working implementation is now consistently returning the following error on iOS: The operation couldn’t be completed. (com.apple.devicecheck.error error 4.) (serverUnavailable) Despite the green status on Apple’s System Status page, this appears to be a backend issue—possibly infrastructure or DNS-related. Notably: The issue affects multiple apps. It is reproducible across different geographies. No code changes were made recently to the attestation logic. We previously reported a similar concern in this thread: App Attest Attestation Failing, but this new occurrence seems unrelated to any client-side cause. Update: An Apple engineer in this thread(https://developer.apple.com/forums/thread/782987) confirmed that the issue was due to a temporary DNS problem and has now been resolved. Can anyone else confirm seeing this today? Any insights from Apple would be appreciated to ensure continued stability. Thanks!

App IPA upgrade loses access to keychaingroup
Hi, Our App relies on a keychain to store certificates and key-value pairs. However, when we upgraded from an older XCode 15.2 (1 year old) app version to a newer version XCode 16.2 (with identical keychain-groups entitlement), we found that the newer ipa cannot see the older keychain group anymore... We tried Testflight builds, but limited to only generating newer versions, we tried using the older App's code, cast as a newer App version, and then upgraded to the newer code (with an even newer app version!). Surprisingly we were able to see the older keychain group. So it seems that there's something different between the packaging/profile of the older (1 year) and newer (current) App versions that seems to cause the new version to not see the old keychainGroup... Any ideas?

mTLS : Guidance on Generating SecIdentity with Existing Private Key and Certificate
Hello, I am currently working on iOS application development using Swift, targeting iOS 17 and above, and need to implement mTLS for network connections. In the registration API flow, the app generates a private key and CSR on the device, sends the CSR to the server (via the registration API), and receives back the signed client certificate (CRT) along with the intermediate/CA certificate. These certificates are then imported on the device. The challenge I am facing is pairing the received CRT with the previously generated private key in order to create a SecIdentity. Could you please suggest the correct approach to generate a SecIdentity in this scenario? If there are any sample code snippets, WWDC videos, or documentation references available, I would greatly appreciate it if you could share them. Thank you for your guidance.

api and data collection app stroe connect
I added a feature to my app that retrieves only app settings (no personal data) from my API hosted on Cloudflare Workers. The app does not send, collect, track, or share any user data, and I do not store or process any personal information. Technical details such as IP address, user agent, and device information may be automatically transmitted as part of the internet protocol when the request is made, but my app does not log or use them. Cloudflare may collect this information. Question: Does this count as “data collection” for App Store Connect purposes, or can I select “No Data Collected”?

Custom Authorization Plugin in Login Flow
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

Securely passing credentials from Installer plug-in to newly installed agent — how to authenticate the caller?
I’m using a custom Installer plug-in (InstallerPane) to collect sensitive user input (username/password) during install. After the payload is laid down, I need to send those values to a newly installed agent (LaunchAgent) to persist them. What I tried I expose an XPC Mach service from the agent and have the plug-in call it. On the agent side I validate the XPC client using the audit token → SecCodeCopyGuestWithAttributes → SecCodeCheckValidity. However, the client process is InstallerRemotePluginService-* (Apple’s view service that hosts all plug-ins), so the signature I see is Apple’s, not mine. I can’t distinguish which plug-in made the call. Any suggestion on better approach ?

DeviceCheck Framework Crash: DCAnalytics nil Dictionary Insertion in Production
We're experiencing crashes in our production iOS app related to Apple's DeviceCheck framework. The crash occurs in DCAnalytics internal performance tracking, affecting some specific versions of iOS 18 (18.4.1, 18.5.0). Crash Signature CoreFoundation: -[__NSDictionaryM setObject:forKeyedSubscript:] + 460 DeviceCheck: -[DCAnalytics sendPerformanceForCategory:eventType:] + 236 Observed Patterns Scenario 1 - Token Generation: Crashed: com.appQueue EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000010 DeviceCheck: -[DCDevice generateTokenWithCompletionHandler:] Thread: Background dispatch queue Scenario 2 - Support Check: Crashed: com.apple.main-thread EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000008 DeviceCheck: -[DCDevice _isSupportedReturningError:] DeviceCheck: -[DCDevice isSupported] Thread: Main thread Root Cause Analysis The DCAnalytics component within DeviceCheck attempts to insert a nil value into an NSMutableDictionary when recording performance metrics, indicating missing nil validation before dictionary operations. Reproduction Context Crashes occur during standard DeviceCheck API usage: Calling DCDevice.isSupported property Calling DCDevice.generateToken(completionHandler:) (triggered by Firebase App Check SDK) Both operations invoke internal analytics that fail with nil insertion attempts. Concurrency Considerations We've implemented sequential access guards around DeviceCheck token generation to prevent race conditions, yet crashes persist. This suggests the issue likely originates within the DeviceCheck framework's internal implementation rather than concurrent access from our application code. Note: Scenario 2 occurs through Firebase SDK's App Check integration, which internally uses DeviceCheck for attestation. Request Can Apple engineering confirm if this is a known issue with DeviceCheck's analytics subsystem? Is there a recommended workaround to disable DCAnalytics or ensure thread-safe DeviceCheck API usage? Any guidance on preventing these crashes would be appreciated.

CryptoKitError
Hi, I am using CryptoKit in my app. I am getting an error sometimes with some users. I log the description to Firebase but I am not sure what is it exactly about.  CryptoKit.CryptoKitError error 2  CryptoKit.CryptoKitError error 3 I receive both of these errors. I also save debug prints to a log file and let users share them with me. Logs are line-by-line encrypted but after getting these errors in the app also decryption of log files doesn't work and it throws these errors too. I couldn't reproduce the same error by myself, and I can't reach the user's logs so I am a little blind about what triggers this. It would be helpful to understand what these errors mean. Thanks

Why won't my AutoFill Credential Provider show up in the context menu of a generic textfield?
I noticed, that even though my AutoFill Credential Provider Extension works with Safari for both Passwords and Passkeys, it doesn't work in context menus inside arbitrary textfields, meanwhile the same is true for the Apple Passwords app. This is a great hit to AutoFill productivity, as my extension is unable to fill textfields by just going to the context menu and clicking AutoFill > Passwords.. Is this a feature only available to Apple via private APIs, or is this something I can interface with? I checked and the Passwords app does use some undocumented but non-private entitlements: [Key] com.apple.authentication-services.access-credential-identities [Value] [Bool] true I also checked the responsible executable for some hints (AutoFillPanelService) however found nothing that would lead me to believe this is a public extension point. Another idea I had was trying to use a macOS Service for this, however Services in the "General" category won't show up in any context menu, only in the Application's Main Menu.

C++ HMAC-SHA256 Signature Works in Python, Fails in C++ — Possible Xcode Runtime Issue?
Hi all, I’m building a macOS-native C++ trading bot, compiled via Xcode. It sends REST API requests to a crypto exchange (Bitvavo) that require HMAC-SHA256 signatures using a pre-sign string (timestamp + method + path + body) and an API secret. Here’s the issue: • The exact same pre-sign string and API secret produce valid responses when signed using Python (hmac.new(secret, msg, hashlib.sha256)), • But when I generate the HMAC signature using C++ (HMAC(EVP_sha256, ...) via OpenSSL), the exchange returns an invalid signature error. Environment: • Xcode 15.3 / macOS 14.x • OpenSSL installed via Homebrew • HMAC test vectors match Python’s output for basic strings (so HMAC lib seems correct) Yet when using the real API keys and dynamic timestamped messages, something differs enough to break verification — possibly due to UTF-8 encoding, memory alignment, or newline handling differences in the Xcode C++ runtime? Has anyone experienced subtle differences between Python and C++ HMAC-SHA256 behavior when compiled in Xcode? I’ve published a GitHub repo for reproducibility: 🔗 https://github.com/vanBaardewijk/bitvavo-cpp-signature-test Thanks in advance for any suggestions or insights. Sascha

Auth Plugin Timeout Issue During Screen Unlock
Hi! We are developing an authentication plugin for macOS that integrates with the system's authentication flow. The plugin is designed to prompt the user for approval via a push notification in our app before allowing access. The plugin is added as the first mechanism in the authenticate rule, followed by the default builtin:authenticate as a fallback. When the system requests authentication (e.g., during screen unlock), our plugin successfully displays the custom UI and sends a push notification to the user's device. However, I've encountered the following issue: If the user does not approve the push notification within ~30 seconds, the system resets the screen lock (expected behavior). If the user approves the push notification within approximately 30 seconds but doesn’t start entering their password before the timeout expires, the system still resets the screen lock before they can enter their password, effectively canceling the session. What I've Tried: Attempted to imitate mouse movement after the push button was clicked to keep the session active. Created a display sleep prevention assertion using IOKit to prevent the screen from turning off. Used the caffeinate command to keep the display and system awake. Tried setting the result as allow for the authorization request and passing an empty password to prevent the display from turning off. I also checked the system logs when this issue occurred and found the following messages: ___loginwindow: -[LWScreenLock (Private) askForPasswordSecAgent] | localUser = >timeout loginwindow: -[LWScreenLock handleUnlockResult:] _block_invoke | ERROR: Unexpected _lockRequestedBy of:7 sleeping screen loginwindow: SleepDisplay | enter powerd: Process (loginwindow) is requesting display idle___ These messages suggest that the loginwindow process encounters a timeout condition, followed by the display entering sleep mode. Despite my attempts to prevent this behavior, the screen lock still resets prematurely. Questions: Is there a documented (or undocumented) system timeout for the entire authentication flow during screen unlock that I cannot override? Are there any strategies for pausing or extending the authentication timeout to allow for complex authentication flows like push notifications? Any guidance or insights would be greatly appreciated. Thank you!

Apply MacOS OS updated without password prompt
Hello, I am currently researching to develop an application where I want to apply the MacOS updates without the password prompt shown to the users. I did some research on this and understand that an MDM solution can apply these patches without user intervention. Are there any other ways we can achieve this? Any leads are much appreciated.

Help with Passkey Registration & Authentication on iOS 17 (Credential Provider + Error Code 1004)
I’m implementing passkey registration and authentication in an iOS 17 app with a credential provider extension, but I’m running into an issue. Setup: I have a credential provider target configured. The app correctly shows the pop-up to register the passkey with my app. My Info.plist is set up properly. Issue: When the following function is triggered: override func prepareInterface(forPasskeyRegistration registrationRequest: ASCredentialRequest) { "code to generate registrationRequest..." let controller = ASAuthorizationController(authorizationRequests: [registrationRequest]) controller.delegate = self controller.presentationContextProvider = self controller.performRequests() } I get the following error: Domain=com.apple.AuthenticationServices.AuthorizationError Code=1004 I do not own the relying party domain (e.g., https://webauthn.io), so I cannot configure an apple-app-site-association file on the website. Question: How can I register and authenticate passkeys on any site that allows passkeys (such as webauthn.io) when I don’t control the webpage? Are there any workarounds or best practices for handling this in iOS 17? Any insights would be greatly appreciated!

deviceOwnerAuthenticationWithCompanion evaluation not working as expected
In one of my apps I would like to find out if users have their device set up to authenticate with their Apple Watch. According to the documentation (https://developer.apple.com/documentation/localauthentication/lapolicy/deviceownerauthenticationwithcompanion) this would be done by evaluating the LAPolicy like this: var error: NSError? var canEvaluateCompanion = false if #available(iOS 18.0, *) { canEvaluateCompanion = context.canEvaluatePolicy(.deviceOwnerAuthenticationWithCompanion, error: &error) } But when I run this on my iPhone 16 Pro (iOS 18.5) with a paired Apple Watch SE 2nd Gen (watchOS 11.5) it always returns false and the error is -1000 "No companion device available". But authentication with my watch is definitely enabled, because I regularly unlock my phone with the watch. Other evaluations of using biometrics just works as expected. Anything that I am missing?

Yubikey Authentication iPad/iOS26
Hey all, Question for the masses.... Does the Yubikey authentication have a OS dependency and it only works with a stable, public OS? Does Azure/Okta/Yubikey beta OS26? My CEO installed iPadOS 26 on his iPad and was not able to authenticate via Yubikey into our company environment. I ran the same scenario on my iPad using iPadOS 26 and I had the same results. Downgrading to iPAdOS doesn't pose these issues. I'm assuming something isn't fine-tuned yet?

App Attest Suddenly Failing in Production — Error 4 (serverUnavailable)
Hi Apple Team and Community, We've encountered a sudden and widespread failure with the App Attest service starting today across multiple production apps and regions. The previously working implementation is now consistently returning the following error on iOS: The operation couldn’t be completed. (com.apple.devicecheck.error error 4.) (serverUnavailable) Despite the green status on Apple’s System Status page, this appears to be a backend issue—possibly infrastructure or DNS-related. Notably: The issue affects multiple apps. It is reproducible across different geographies. No code changes were made recently to the attestation logic. We previously reported a similar concern in this thread: App Attest Attestation Failing, but this new occurrence seems unrelated to any client-side cause. Update: An Apple engineer in this thread(https://developer.apple.com/forums/thread/782987) confirmed that the issue was due to a temporary DNS problem and has now been resolved. Can anyone else confirm seeing this today? Any insights from Apple would be appreciated to ensure continued stability. Thanks!

App IPA upgrade loses access to keychaingroup
Hi, Our App relies on a keychain to store certificates and key-value pairs. However, when we upgraded from an older XCode 15.2 (1 year old) app version to a newer version XCode 16.2 (with identical keychain-groups entitlement), we found that the newer ipa cannot see the older keychain group anymore... We tried Testflight builds, but limited to only generating newer versions, we tried using the older App's code, cast as a newer App version, and then upgraded to the newer code (with an even newer app version!). Surprisingly we were able to see the older keychain group. So it seems that there's something different between the packaging/profile of the older (1 year) and newer (current) App versions that seems to cause the new version to not see the old keychainGroup... Any ideas?

mTLS : Guidance on Generating SecIdentity with Existing Private Key and Certificate
Hello, I am currently working on iOS application development using Swift, targeting iOS 17 and above, and need to implement mTLS for network connections. In the registration API flow, the app generates a private key and CSR on the device, sends the CSR to the server (via the registration API), and receives back the signed client certificate (CRT) along with the intermediate/CA certificate. These certificates are then imported on the device. The challenge I am facing is pairing the received CRT with the previously generated private key in order to create a SecIdentity. Could you please suggest the correct approach to generate a SecIdentity in this scenario? If there are any sample code snippets, WWDC videos, or documentation references available, I would greatly appreciate it if you could share them. Thank you for your guidance.

api and data collection app stroe connect
I added a feature to my app that retrieves only app settings (no personal data) from my API hosted on Cloudflare Workers. The app does not send, collect, track, or share any user data, and I do not store or process any personal information. Technical details such as IP address, user agent, and device information may be automatically transmitted as part of the internet protocol when the request is made, but my app does not log or use them. Cloudflare may collect this information. Question: Does this count as “data collection” for App Store Connect purposes, or can I select “No Data Collected”?

Custom Authorization Plugin in Login Flow
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

Securely passing credentials from Installer plug-in to newly installed agent — how to authenticate the caller?
I’m using a custom Installer plug-in (InstallerPane) to collect sensitive user input (username/password) during install. After the payload is laid down, I need to send those values to a newly installed agent (LaunchAgent) to persist them. What I tried I expose an XPC Mach service from the agent and have the plug-in call it. On the agent side I validate the XPC client using the audit token → SecCodeCopyGuestWithAttributes → SecCodeCheckValidity. However, the client process is InstallerRemotePluginService-* (Apple’s view service that hosts all plug-ins), so the signature I see is Apple’s, not mine. I can’t distinguish which plug-in made the call. Any suggestion on better approach ?
