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 was testing an app with AppleSignIn with a Firebase backend and wanted to test account deletion functionality. I was unaware of needing to revoke the token with Apple before proceeding with account deletion. Now, when I try to create a new account with the same appleId email, the token passed to Firebase is invalid and the login fails. As such, I am blocked from testing my app with authenticated Apple users, so I'm trying to understand what the workaround is. Thanks in advance!

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 Also, I've found that all my certificates have been revoked!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

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

With the new ios 26 update, certain numbers will be filtered into other inboxes within imessage. What numbers are classified as "known", and will not be moved into these filters. Do they need to be a contact in your phone, or if a business texts you how will that be filtered?

Our product includes a background sync process that synchronizes credentials between devices. We need to update ASCredentialIdentityStore when credentials are changed, we have noticed that the ASCredentialIdentityStore.shared.saveCredentialIdentities() fails to run when the device is locked. Is it possible to update ASCredentialIdentityStore when the device is locked?

Hi, I've been developing an app with a server. I'm hosting the server on an IPv6-ONLY network that's hidden behind the CloudFlare, so it works flawlessly from the clients point of view, but if server needs to access external resources, they need to be accessible over IPv6. As it turns out, appleid.apple.com doesn't support IPv6, and the Sign In with Apple happens with the help of my server. So, I can't sign users in as Apple doesn't support IPv6 traffic on appleid.apple.com. Are there any plans to support IPv6 in the near future, or should I work on the networking setup to enable IPv4 just for the Apple SSO? Or maybe there's a clever workaround I'm missing?

Hi, Just follow the related post to implement this method in the app, but it gave me error, like: "An SSL error has occurred and a secure connection to the server cannot be made" the info plist configuration like below, NSPinnedDomains mysite.com NSIncludesSubdomains NSPinnedCAIdentities SPKI-SHA256-BASE64 r/mIkG3eEpVdm+u/ko/cwxzOMo1bk4TyHIlByibiA5E= The pub key is right for me, since it works when I use different pub key pinning through URLSession interface. So here, I dont know where to start the troubleshooting, any advice would be appreciated.

I'm currently working on a project in Swift where I need to digitally sign a PDF file. I have the following resources available: Private Key stored in the iOS Keychain with a tag. Public Key also stored in the iOS Keychain with a tag. A valid certificate stored as a PEM string. I need to digitally sign a PDF file with the above keys and certificate, but I'm struggling to find a clear and straightforward example or guidance on how to achieve this in Swift. Specifically, I’m looking for help with: Creating the digital signature using the private key and certificate. Embedding this signature into the PDF file. Any considerations I should be aware of regarding the format of the signed PDF (e.g., CMS, PKCS7, etc.). If anyone has experience with digitally signing PDFs in Swift, I would greatly appreciate your guidance or code examples. Thank you in advance!

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

I have two applications, and I recently decided to add the Apple Sign In feature. Initially, I configured it for one of the apps as the Primary ID for this feature. Everything worked well, and I decided to add it to the second app. I made a mistake and used the First app as Primary ID using the "Group with an existing primary App ID" flag. Now, when I sign in using the second app, I don't see it in the list of apps in iPhone Settings for Apple Sign In; I only see the primary app. And with that, I no longer see a prompt for sharing/hiding email, and I am unable to revoke credentials correctly. I decided to change the Second app's Sign-in config and set it as the Primary ID for the feature. I was hoping to get two apps independent for the SignIn. However, it doesn't seem to make a difference. The second app behaves the same way, as long as the first app used SignIn, the second one always thinks that the user has already used that feature and never shows the correct prompt. Is there something I missed after changing the Configuration?

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.

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’d like to submit a feature request regarding the availability of Foundation Models in MessageFilter extensions. Background MessageFilter extensions play a critical role in protecting users from spam, phishing, and unwanted messages. With the introduction of Foundation Models and Apple Intelligence, Apple has provided powerful on-device natural language understanding capabilities that are highly aligned with the goals of MessageFilter. However, Foundation Models are currently unavailable in MessageFilter extensions. Why Foundation Models Are a Great Fit for MessageFilter Message filtering is fundamentally a natural language classification problem. Foundation Models would significantly improve: Detection of phishing and scam messages Classification of promotional vs transactional content Understanding intent, tone, and semantic context beyond keyword matching Adaptation to evolving scam patterns without server-side processing All of this can be done fully on-device, preserving user privacy and aligning with Apple’s privacy-first design principles. Current Limitations Today, MessageFilter extensions are limited to relatively simple heuristics or lightweight models. This often results in: Higher false positives Lower recall for sophisticated scam messages Increased development complexity to compensate for limited NLP capabilities Request Could Apple consider one of the following: Allowing Foundation Models to be used directly within MessageFilter extensions Providing a constrained or optimized Foundation Model API specifically designed for MessageFilter Enabling a supported mechanism for MessageFilter extensions to delegate inference to the containing app using Foundation Models Even limited access (e.g. short text only, strict execution limits) would be extremely valuable. Closing Foundation Models have the potential to significantly raise the quality and effectiveness of message filtering on Apple platforms while maintaining strong privacy guarantees. Supporting them in MessageFilter extensions would be a major improvement for both developers and users. Thank you for your consideration and for continuing to invest in on-device intelligence.

Hi, I've recently tested my custom AuthorizationPlugin on macOS 15 (Sequoia) and I'm seeing a significant change in rendering (or precisely not rendering) the control returned by my SFAuthorizationPluginView's subclass' viewForType method comparing to macOS 14. (I developed and tested my solution on macOS 14 earlier this year). I use SFAuthorizationPluginView to present a NSView (Custom view) which contains a NSSecureTextField and a NSImageView. I show my custom plugin after the user successfully entered username and password (or only the password if the List of Users is configured in System Settings) into the builtin fields provided by loginwindow:login, so injecting my plugin:mechanism pair into the system.login.console after loginwindow:success. (I need to run my mechanism after builtin:authenticate,privileged since my plugin relies on the authentication result coming from my custom PAM module). This setup now however doesn't seem to be working: after entering the (username and) password, the circular spinner appears and my NSView never gets rendered. I've found a workaround to place my plugin:mechanism pair after loginwindow:done, so in the end of the whole authorization chain. I tried to run the good old NameAndPassword bundle, injecting it into the place of the loginwindow:login. Controls are being rendered correctly, but if I place it even right after loginwindow:login it doesn't get rendered as my custom plugin. Is anybody aware if there's anything has intentionally been changed in macOS 15? Or may it be a bug? I guess the original intention of the SFAuthorizationPluginView class was to overwrite/redefine the UI instead of the builtin username + password field, so if I look at it that way it's expected that the view it contains only gets rendered if we use it instead of loginwindow:login. On the other hand this hasn't been the case until now. Thanks for any help!

Hello I am trying to release an application using EXPO ROUTER + EXPO RN WEB. I am trying to implement Apple Login using Firebase. I have already put necessary info in both App Store Connect and Firebas console. Now I am so confused what I have to do next. What are some resource I could use or tips you could possibly give me when making apple login available using firebase. Pleas all helps are welcomed and needed

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 have an Autofill Passkey Provider working for Safari and Chrome via WebAuthn protocol. Unfortunately, Chrome will not offer my extension as a logon credential provider unless I add the credential to the ASCredentialIdentityStore. I wonder what is the best way to access the ASCredentialIdentityStore from an AutoFill extension? I understand I cannot access it directly from the extension context, so what is the best way to trigger my container app to run, based on a new WebAuthn registration? The best I can think of so far is for the www site to provide an App Link to launch my container app as part of the registration ceremony. Safari will offer my extension even without adding it to the ASCredentialIdentityStore, so I guess I should file a request with Chrome to work this way too, given difficulty of syncing ASCredentialIdentityStore with WebAuthn registration.

Hi, preivously on appleid.apple.com, navigating to this page on safari would show the in-app modal to continue with Apple. Now with account.apple.com, this is not the case. We are not seeing the in-app modal to continue with Apple
