In response to inquiries from users, we have confirmed the following phenomenon. If you select "Private email address" in the flow of new user registration with Apple ID, you will not receive the verification code email when performing two-factor authentication. ■User impact If you use your Apple ID to link an external account without making your email address public, you will not receive the authentication code during two-factor authentication and will not be able to proceed. The date and time of the impact is currently unknown. ◎Impact 1: New registration If you select "Private email address" in the flow of registering a new user with Apple ID, the verification code will not be received during two-factor authentication and registration will not be completed. ◎Impact 2: Login of existing account When two-factor authentication is required for an existing account registered with Apple ID set to "Private email address," the verification code is not received and the user cannot log in. →If you have not registered a login method other than Apple ID for the relevant account, there is no other way to log in. ■About workarounds ・I thought that I could avoid this issue by canceling the private setting of my Apple ID, but I was unable to do so. →There is currently no workaround found for existing users who are experiencing this issue. ・However, the scope of influence is limited. ■Cause investigation status Premise: For an Apple ID whose email address is not made public, the two-factor authentication authentication code email follows the following route. ①CDC/GIGYA miraiz-persol.jp (SendGrid) Apple's email server (relay server to hide the user's real email address) User mailbox →Since '1' are working, the problem seems to have occurred after the connection from ② or ③. (At this stage, we cannot determine who is at fault: the user, MIRAIZ, or Apple. We are currently investigating.) ◎Hypothesis ・Is there something wrong with Apple's mail server? ・Is it not delivered because the user's mailbox is full? ■Questions, research, and responses we would like to receive Please check the following two points and reply. 1st point As shown in the attached image, there seems to be no problem with the SPF settings. Is it possible to check to see if any errors have occurred with Apple's mail server? 2nd point Are there any cases where you still can't receive emails even if you deactivate your Apple ID? I would like to know if there are any patterns in which emails are not being delivered in terms of past inquiries or overall specifications

When presenting a cookie banner for GDPR purposes, should ATT precede the cookie banner? It seems that showing a Cookie Banner and then showing the ATT permission prompt afterwards (if a user elects to allow cookies/tracking) would be more appropriate. Related question: Should the “Allow Tracking” toggle for an app in system settings serve as a master switch for any granular tracking that might be managed by a 3rd party Consent Management Platform? If ATT is intended to serve as a master switch for tracking consent, if the ATT prompt is presented before a cookie banner, should the banner even appear if a user declines tracking consent? I’m not finding any good resources that describe this flow in detail and I’m seeing implementations all over the place on this. Help! Thanks!!!

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 implemented a feature to receive name and email address after Sign in with Apple, and it works perfectly in our testing. However, during the app review, they says it doesn't work, and the app is rejected. Why does it work differently?

I’m implementing Passkey registration on iOS using ASAuthorizationPlatformPublicKeyCredentialProvider. On the server side, I’m using a WebAuthn library that throws the error UnexpectedRPIDHash: Unexpected RP ID hash during verifyRegistrationResponse(). Domain: pebblepath.link (publicly routable, valid SSL certificate, no warnings in Safari) Associated Domains in Xcode**: webcredentials:pebblepath.link AASA file: { "applinks": { "apps": [] }, "webcredentials": { "apps": [ "H33XH8JMV6.com.reactivex.pebblepath" ] } } Xcode Configuration: Team ID: H33XH8JMV6 Bundle ID: com.reactivex.pebblepath Associated Domains: webcredentials:pebblepath.link Logs: iOS clientDataJSON shows "origin": "https://pebblepath.link". Server logs confirm expectedOrigin = "https://pebblepath.link" and expectedRPID = "pebblepath.link". Despite this, the server library still errors out: finishRegistration error: UnexpectedRPIDHash. I’ve verified that: The domain has a valid CA-signed SSL cert (no Safari warnings). The AASA file is reachable at https://pebblepath.link/.well-known/apple-app-site-association. The app’s entitlements match H33XH8JMV6.com.reactivex.pebblepath. I’ve removed old passkeys from Settings → Passwords on the device and retried fresh. I’m testing on a real device with iOS 16+; I am using a Development provisioning profile, but that shouldn’t cause an RP ID mismatch as long as the domain is valid. Every log indicates that the domain and origin match exactly, but the WebAuthn library still throws UnexpectedRPIDHash, implying iOS is embedding a different (or unrecognized) RP ID hash in the credential. Has anyone else encountered this with iOS passkeys and a valid domain/AASA setup? Is there an extra step needed to ensure iOS recognizes the domain for passkey registration? Any guidance or insights would be greatly appreciated!

Hi, my app is receiving all keyboard events through Input Monitoring preference. It completely stopped to work on macOS 15 Sequoia and I have no idea why. Where can I read what has been changed in Input Monitoring? Thanks!

Hi Apple Team and Community, We encountered a sudden and widespread failure related to the App Attest service on Friday, July 25, starting at around 9:22 AM UTC. After an extended investigation, our network engineers noted that the size of the attestation objects received from the attestKey call grew in size notably starting at that time. As a result, our firewall began blocking the requests from our app made to our servers with the Base64-encoded attestation objects in the payload, as these requests began triggering our firewall's max request length rule. Could Apple engineers please confirm whether there was any change rolled out by Apple at or around that time that would cause the attestation object size to increase? Can anyone else confirm seeing this? Any insights from Apple or others would be appreciated to ensure continued stability. Thanks!

Like many/most developers, I gave Connect the info required to comply with the DSA. Perhaps unlike most, I always give unique email addresses so that I can easily track the source of abuse. Yesterday I finally had a phish come in to my DSA address claiming "Message blocked" and doing the standard click-to-login-for-details FOMO bait. So, yep, DSA just becomes yet another public database that malicious actors can use to target you. It would be really nice if Apple provided a way to supply our contact info only for legitimate business purposes. Mail Privacy Protection (or similar) for this would be a start.

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

this is my monitor image that shows DeviceCheck api responding very slowly.

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?

When using Apple's Journal app through iPhone Mirroring, the user is allowed to authenticate via TouchID on the Mac instead of requiring you to unlock your phone, authenticate and then re-lock it to access it again in iPhone Mirroring. Any other app that's using a call to authenticate via FaceID can't do this under iPhone Mirroring. Is there a new API call for this, or is it still a private API for Apple only?

Our business model is to identify Frauds using our advanced AI/ML model. However, in order to do so we need to collect many device information which seems to be ok according to https://developer.apple.com/app-store/user-privacy-and-data-use/ But it's also prohibited to generate a fingerprint, so I need more clarification here. Does it mean I can only use the data to identify that a user if either fraud or not but I cannot generate a fingerprint to identify the device? If so, I can see many SKD in the market that generates Fingerprints like https://fingerprint.com/blog/local-device-fingerprint-ios/ and https://shield.com/?

While I was submitting a new feedback today for an iPhone/iPad storage issue, I saw a new log called “iOS storage log”. I could find no reference to this when I searched online. It made me wonder if it was new and if it contained personal data? Most of us only have one device, with all our personal data. Therefore, I’d appreciate any input on what personal data these logs contain.

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'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!

Hi everyone, I'm developing an iOS app using the AppsFlyer SDK. I understand that starting with iOS 14.5, if a user denies the App Tracking Transparency (ATT) permission, we are not allowed to access the IDFA or perform cross-app tracking. However, I’d like to clarify which in-app events are still legally and technically safe to send when the user denies ATT permission. Specifically, I want to know: Is it acceptable to send events like onboarding_completed, paywall_viewed, subscription_started, subscribe, subscribe_price, or app_opened if they are not linked to IDFA or any form of user tracking? Would sending such internal behavioral events (used purely for SKAdNetwork performance tracking or in-app analytics) violate Apple’s privacy policy if no device identifiers are attached? Additionally, if these events are sent in fully anonymous form (i.e., not associated with IDFA, user ID, email, or any identifiable metadata), does Apple still consider this a privacy concern? In other words, can onboarding_completed, paywall_viewed, subsribe, subscribe_price, etc., be sent in anonymous format without violating ATT policies? Are there any official Apple guidelines or best practices that outline what types of events are considered compliant in the absence of ATT consent? My goal is to remain 100% compliant with Apple’s policies while still analyzing meaningful user behavior to improve the in-app experience. Any clarification or pointers to documentation would be greatly appreciated. Thanks in advance!

Hey, there are plans to design a government app. When a citizen will login they will see their passport, driving license etc... What is the solution of avoiding mandatory in-app user data deletion?
