I read online that there is no way to extract the call log from an iPhone. I want to develop an app to help people remember to call their mom, and if they did, the "nagging" would disappear automatically. I'm looking for any workaround to know when a user called someone, without having them log it manually.

I have a project with a single app target that serves two environments, and two schemes, one for each env, using xcconfig files for defining environment-specific stuff. I'm trying to figure this out for months, so I've tried multiple approaches throughout this period: Have a single domain in "Associated domains" in Xcode, defined as webcredentials:X where X gets replaced using a value from xcconfig. Have two domain entries in "Associated domains" webcredentials:PROD_DOMAIN and webcredentials:STAGING_DOMAIN. Have a different order of domains Results are very interesting: whatever I do, whatever approach I take, password autofill works on staging, but doesn't work on production. I'm aware that we need to test production on Test Flight and AppStore builds. That's how we're testing it, and it's not working. Tested on multiple devices, on multiple networks (wifi + mobile data), in multiple countries.. you name it. The server side team has checked their implementation a dozen times; it's all configured properly, in the exact same way across environments (except bundle ID, ofc). We tried a couple websites for validating the apple-app-site-association file, and while all of those are focused on testing universal links, they all reported that the file is configured properly. Still, password autofill doesn't work. I prefer not to share my app's domains publicly here. Ideally I would contact Apple Developer Support directly, but they now require a test project for that, and since 'a test project' is not applicable to my issue, I'm posting here instead.

I must be missing something. How can an iphone that is in lockdown mode, using ONLY data, no Bluetooth connected and only one singular iPhone have seven UNLISTED items on the local network in privacy and settings?

I'm trying to setup device attestation. I believe I have everything setup correctly but the final step of signature validation never succeeds. I've added validation on the client side for debugging and it doesn't validate using CryptoKit. After the assertion is created, I try to validate it: assertion = try await DCAppAttestService.shared.generateAssertion(keyId, clientDataHash: clientDataHash) await validateAssertionLocallyForDebugging(keyId: keyId, assertionObject: assertion, clientDataHash: clientDataHash) In the validateAssertionLocallyForDebugging method, I extract all the data from the CBOR assertionObject and then setup the parameters to validate the signature, using the key that was created from the original attestation flow, but it fails every time. I'm getting the public key from the server using a temporary debugging API. let publicKeyData = Data(base64Encoded: publicKeyB64)! let p256PublicKey = try P256.Signing.PublicKey(derRepresentation: publicKeyData) let ecdsaSignature = try P256.Signing.ECDSASignature(derRepresentation: signature) let digestToVerify = SHA256.hash(data: authenticatorData + clientDataHash) print(" - Recreated Digest to Verify: \(Data(digestToVerify).hexDescription)") if p256PublicKey.isValidSignature(ecdsaSignature, for: digestToVerify) { print("[DEBUG] SUCCESS: Local signature validation passed!") } else { print("[DEBUG] FAILED: Local signature validation failed.") } I have checked my .entitlements file and it is set to development. I have checked the keyId and verified the public key. I have verified the public key X,Y, the RP ID Hash, COSE data, and pretty much anything else I could think of. I've also tried using Gemini and Claude to debug this and that just sends me in circles of trying hashed, unhashed, and double hashed clientData. I'm doing this from Xcode on an M3 macbook air to an iPhone 16 Pro Max. Do you have any ideas on why the signature is not validating with everything else appears to be working? Thanks

Hi folks We have a Developer ID Application which we create using electron. We made our last release for our Application on Nov'24 which was correctly working. Using the same code, we tried creating a notarized application again which started showing the following error while opening our Application. Monterey- M2- When we directly run the dmg on the dev machine, it does not give us the prompt. But if we download it from somewhere and run, the prompt comes up even in dev machine. We executed some commands to verify the notarization: 1- spctl --assess -vv /Applications/Refresh\ Pro.app On both dev machine and non-dev machine, the output was "accepted" /Applications/Refresh Pro.app: accepted source=Notarized Developer ID origin=Developer ID Application: Prograde Digital Incorporated (*******) 2- xcrun stapler validate /Applications/Refresh\ Pro.app On dev machine, we executed this command and the output is as follows. Processing: /Applications/Refresh Pro.app The validate action worked! 3- codesign -vvv --deep --strict /Applications/Refresh\ Pro.app/ /Applications/Refresh Pro.app: valid on disk /Applications/Refresh Pro.app: satisfies its Designated Requirement We have created a bug attaching the dmg. Please suggest anything we can try to make the release out the door. Bug link- https://feedbackassistant.apple.com/feedback/16811025

Hello Apple Developer Support, I am experiencing an issue with Apple Sign-In and Private Relay across two separate organizations. I have a web application that supports Apple Sign-In, configured under organization ID: 62P86SVLK4. Users can log in using their Apple accounts with the Hide My Email (Private Relay) feature enabled. This web application was created a long time ago and initially only had a web component. Recently, we developed a native mobile version of this application, which also supports Apple Sign-In. However, due to business constraints, the mobile application was created under a different organization ID: T6JT35U9NW. The Issue Since the web and mobile applications are registered under different organizations, accounts created using Apple Sign-In with Private Relay are not recognized across both applications. For example: A user creates an account in the web app using Apple Sign-In with Private Relay. When they attempt to log in to the mobile app with Apple Sign-In (also using Private Relay), authentication fails because the generated Private Relay email addresses do not match between the two organizations. Question Is there any way to link Private Relay accounts across these two organizations so that users who signed up on the web application can log in to the mobile application seamlessly? I appreciate any guidance on how to resolve this issue. Best regards, Kamil Gronert

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?

Hi everyone, I'm looking for a way to configure Passkey on iOS so that authentication is only possible using FaceID or TouchID. Specifically, I want to disable the use of passcodes and QR codes for authentication. Additionally, is there a method to detect if the authentication was done using a passcode or QR code? Thanks for your help!

I’d like to confirm something regarding the hosting of the apple-app-site-association (AASA) file. We have a server that publicly hosts the AASA file and is accessible globally. However, this server sits behind an additional security layer (a security server/reverse proxy). My question is: Will this security layer affect Apple’s ability to access and validate the AASA file for Universal Links or App Clips? Are there specific requirements (e.g. headers, redirects, TLS versions, etc.) that we need to ensure the security server does not block or modify? Any guidance or best practices would be appreciated. Thanks!

I have a very basic binary question around passkeys. Assuming everything is on latest and greatest version with respect to iOS, when user starts creating a passkey in platform-authenticator i.e., iCloudKeyChain (Apple Password Manager) , will iCloudKeyChain create a hardware-bound passkey in secure-enclave i.e., is brand new key-pair created right inside Secure-enclave ? OR will the keypair be created in software i.e., software-bound-passkey ?? i.e., software-bound keypair and store the private-key locally in the device encrypted with a key that is of course created in secure-enclave.

Cannot find developer mode in iPhone 16. Please help me resolve this

Hi, is it somehow possible to access a key that was generated by the DCAppAttestService generateKey() function? I need to be 100% sure that no actor from within or outside of my app can access the generated key with the DeviceCheck Framework. It would also be helpful to get some official resources to the topic. Thank you in advance, Mike

The header documentation for the (deprecated) LAContext.evaluatedPolicyDomainState property contains the following: @warning Please note that the value returned by this property can change exceptionally between major OS versions even if the state of biometry has not changed. I noticed that the documentation for the new LAContext.domainState property does not contain a similar warning. I also found this related thread from 2016/17. Is the domainState property not susceptible to changes between major OS versions? Or is this generally not an issue anymore?

override func prepareInterface(forPasskeyRegistration registrationRequest: any ASCredentialRequest) int this function how can i get the "challenge" from user agent, the params "challenge" need to be used in webauthn navigator.credentials.create

I am developing an Authorization plugin for macOS that should be invoked when a user unlocks their device from the lock screen. Based on advice from the other threads in these forums, I have understood that: The plugin needs to use SFAuthorizationPluginView The auth db entries to modify are system.login.screensaver and authenticate I found the NameAndPassword sample and after making some tweaks to it was able to get it to work from screensaver unlock. I am trying to add Webview-based authentication to the plugin, but have not had any success. The plugin window's width does not change (though the height does) and only a small portion of the HTML gets rendered. Is Webview-based authentication supported with SFAuthorizationPluginView? Are there any alternatives?

Hello, I am currently implementing a biometric authentication registration flow using WebAuthn. I am using ASAuthorizationPlatformPublicKeyCredentialRegistrationRequest, and I would like to know if there is a way to hide the "Save to another device" option that appears during the registration process. Specifically, I want to guide users to save the passkey only locally on their device, without prompting them to save it to iCloud Keychain or another device. If there is a way to hide this option or if there is a recommended approach to achieve this, I would greatly appreciate your guidance. Also, if this is not possible due to iOS version or API limitations, I would be grateful if you could share any best practices for limiting user options in this scenario. If anyone has experienced a similar issue, your advice would be very helpful. Thank you in advance.

Hi everyone, I am trying to use ASWebAuthenticationSession to authorize user using OAuth2. Service Webcredentials is set. /.well-known/apple-app-site-association file is set. When using API for iOS > 17.4 using new init with callback: .https(...) everything works as expected, however i cannot make .init(url: ,callbackURLScheme: ....) to work. How can i intercept callback using iOS <17.4? Do I really need to use universal links? callbackURL = https://mydomain.com/auth/callback

I have a launch daemon that's using the Endpoint Security framework which also is causing high memory usage (in Activity Monitor memory column shows for example 2GB and Real Memory 11MB) when building a big project in Xcode. Is it some kind of memory caching by the system? leaks -forkCorpse seems to not show any leaks. How can I attach with heap or Instruments without the process being killed with "ENDPOINTSECURITY, Code 2 EndpointSecurity client terminated because it failed to respond to a message before its deadline"?

Dear Apple Developer Support, We are currently encountering a recurring issue with the DeviceCheck API across multiple devices in our production environment. The following error is frequently returned: com.apple.devicecheck.error 0 We would like to ask the following: What are the possible underlying causes that could lead to this specific error code (0) in the DeviceCheck API? Is there any known behavior or condition where Wi-Fi network configurations (e.g., DNS filtering, proxy settings, captive portals) could result in this error? Are there known timeouts, connectivity expectations, or TLS-level requirements that the DeviceCheck API enforces which could fail silently under certain network conditions? Is this error ever triggered locally (e.g., client library-level issues) or is it always from a failed communication with Apple’s servers? Any technical clarification, documentation, or internal insight into this error code would be greatly appreciated. This would help us significantly narrow down root causes and better support our users

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?
