Hi, I have a question about UIDevice identifierForVendor. I am distributing 3 apps using an enterprise account. All apps use the same developer account and certificates. The bundle IDs of the apps are as follows: com.abc.inhouse.mail com.abc.searchent com.abc.noteent In the Enterprise builds, apps 1 and 2 share the same identifierForVendor (IDFV). However, app 3 has a different IDFV value. According to Apple documentation, the IDFV is determined based on the bundle ID when distributing through Enterprise. Why does app 3 have a different IDFV? Are there any other factors besides the bundle ID that affect the IDFV in Enterprise builds? Please help me figure this out. Thank you for your time!

I managed to lose my password in a mixup with my password manager. It has taken me a few hours to work out how to reset it. Following the forgotten password link on the sign in page only takes you to a point where you are asked to reset the password on your iCloud user id. If they are one and the same that's ok. Mine aren't. I eventually found the answer: in the settings app choose developer 2 scroll to the end and choose the sandbox apple account 3. choose this and reset

When developing and testing using my phone I got prompted for allowing app tracking. I later uploaded a build to TestFlight, deleted the old testing app and installed the TestFlight build. I am now stuck in an infinite loop of not getting prompted for allowing app tracking for the app. When entering the app settings the toggle for tracking never appears which leaves me not able to enter the app's content. My guess is that the prompt can only be shown once for the app bundle, but there has to be a way for me to get prompted again without changing the app bundle id. Help is appreciated since this app is scheduled to be published in a week.

Hi team, We are experiencing an issue where some users in China are unable to create passkeys due to authentication errors. This is the UI flows The method we use to prompt users is passkey creation. Technically, this is implemented using Apple’s AuthenticationServices framework. We create an instance of ASAuthorizationController and conform to ASAuthorizationControllerDelegate to handle the results of the authentication attempt. In failure cases, we receive ASAuthorizationError.failed (code 1004), along with some additional details describing the nature of the failure. However, we are currently unable to determine the exact root cause of this issue or how to resolve it. At this point, we can only make assumptions based on the limited error information provided. Our current hypothesis is that due to network restrictions, Apple may be unable to reach the .well-known endpoint where we host the associated domain file. Alternatively, even if the file is successfully loaded and cached to Apple’s CDN, the system in China may not be able to reach the CDN itself. We would greatly appreciate it if you could help us understand what might be causing this problem and guide us on how we can resolve it effectively. Thanks, Hung

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.

You can then choose to add it to the keychain or not. However, it requires a PKCS#12 as input. 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.

There is a sudden surge of users in our apps with invalidated biometrics. Even though the issue is being handled correctly and the user has another way to login, some of the users forgot their passwords and they can not login. Is there any known issue with Biometrics in iOS 18.3.2 or later? There is a (possible) related discussion here: https://discussions.apple.com/thread/256011565

I am running a service available on both an app and a web platform with "Sign In with Apple." Should I store the tokens separately, or should I overwrite them in a single storage location? When a user requests to sign out, should I revoke both the app and web tokens, or will revoking the app token automatically cover the web token as well?

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”?

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?

I’m considering storing some sensitive information in the userID field of a passkey, as described in the createCredentialRegistrationRequest method.(link to method). I'm aware of the largeBlob extension introduced in iOS 17+, but it doesn't meet my needs since I want to create a cross-platform passkey that can be used across various devices — and currently, not many devices support the largeBlob extension. According to W3C documentation, the userID field is not considered private information and can be displayed to the user without requiring a verification process. Based on my understanding, it's also not encrypted, which means it might be accessible with physical access to the device. So here are my questions: How do Apple devices (especially iPhones) handle the userID field in their authenticators? Is it possible to access the userID without user verification, as permitted by the W3C specification? Are there any alternative methods to access the userID value stored in a passkey on Apple devices?

Hello. I want to do the following and need your help. I want to import a certificate (pkcs#12) into my macOS keychain with a setting that prohibits exporting the certificate. I want to import the certificate (pkcs#12) into my login keychain or system keychain. I was able to achieve [1] with the help of the following threads, but have the following problems. https://developer.apple.com/forums/thread/677314?answerId=824644022#824644022 how to import into login keychain or system keychain How to achieve this without using the deprecated API To import into the login keychain, I could use the “SecKeychainCopyDefault” function instead of the “SecKeychainCopySearchList” function, However, both of these functions were deprecated APIs. https://developer.apple.com/documentation/security/seckeychaincopysearchlist(_:) https://developer.apple.com/documentation/security/seckeychaincopydefault(_:) I checked the following URL and it seems that using the SecItem API is correct, but I could not figure out how to use it. https://developer.apple.com/documentation/technotes/tn3137-on-mac-keychains Is there any way to import them into the login keychain or system keychain without using these deprecated APIs?

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.

Developers of our e-shop are preparing to enable Apple Sign In for account login. Apple ID verification is conducted via the domain appleid.apple.com, and the responses should be coming back from the following two Apple IP addresses: IPv4 Address: 17.32.194.6 IPv4 Address: 17.32.194.37 Question is whether these addresses are correct and if they remain unchanged over time. Alternatively, it is existing an official list of IP addresses that may be used for Apple Sign In verification response? This is necessary to ensure precise network communication settings and protection by F5 security solution. Thanks a lot for answers.

I’ve come to discover over the course of three weeks of trying to gain access to my original iTunes account that because of the old security protocols I cannot get access to my music. Apple has said there is no way to access that data without being able to send a reset to the old deleted email attached to that data. That said Cox deleted all of my emails when they migrated over to yahoo so I cannot send an email to reset password to gain access and Apple does not have a protocol in place even though it’s very clear. The current account is linked to the old account. Any of your developers out there have an idea on how I can get past this because the birthdate and the username are not matching up to what they should be. Appreciate your brain muscle guys. It’s a lifetime of music.

Hi, We're in the process of implementing Apple's App Integrity, but am getting stalled due to missing documents. Can anyone assist with this? We've been following https://developer.apple.com/documentation/devicecheck/validating-apps-that-connect-to-your-server to make the necessary updates, but have come up short with where the document references decoding the Attestation Object. Can we get more information here and how the decoding process work?

Our service has ended and the app has been removed from the App store. This app supported Sign in with Apple, but even if I try to revoke the account from the iOS settings or account.apple.com on the web, but can't delete it and no error is displayed. Does anyone know the cause of this problem or have encountered it? I'm not sure if it's related, but this app was previously transferred from another organization.

We are using Apple's PSSO to federate device login to out own IdP. We have developed our own extension app and deployed it using MDM. Things works fine but there are 2 issues that we are trying to get to the root cause - On some devices after restarting we see an error message on the logic screen saying "The registration for this device is invalid and must be repaired" And other error message is "SmartCard configuration is invalid for this account" For the 1st we have figured out that this happens when the registration doesn't happen fully and the key is not tied to the user so when the disk needs to be decrypted at the FileVault screen the issue is raised. For the "SmartCard configuration is invalid for this account" issue also one aspect is invalid registration but there has been other instances as well where the devices were registered completely but then also the the above error was raised. We verified the registration being completed by checking if the SmartCard is visible in the System Report containing the key. Has anyone seen the above issues and any possible resolution around it?

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

Hello Apple Team We are integrating App Attest with our backend and seeing a 400 Bad Request response when calling the attestation endpoint.

Hello Apple Developer Community, We have been experiencing a persistent notification issue in our application, Flowace, after updating to macOS 15 and above. The issue is affecting our customers but does not occur on our internal test machines. Issue Description When users share their screen using Flowace, they receive a repetitive system notification stating: "Flowace has accessed your screen and system audio XX times in the past 30 days. You can manage this in settings." This pop-up appears approximately every minute, even though screen sharing and audio access work correctly. This behavior was not present in macOS 15.1.1 or earlier versions and appears to be related to recent privacy enhancements in macOS. Impact on Users The frequent pop-ups disrupt workflows, making it difficult for users to focus while using screen-sharing features. No issues are detected in Privacy &amp; Security Settings, where Flowace has the necessary permissions. The issue is not reproducible on our internal test machines, making troubleshooting difficult. Our application is enterprise level and works all the time, so technically this pop only comes after a period of not using the app. Request for Assistance We would like to understand: Has anyone else encountered a similar issue in macOS 15+?
