Hello,
I have now been looking for a while of a way to get the number of MAU of my appstore app through the apple connect API. I ended up thinking i might actually be able to compute it with https://developer.apple.com/documentation/analytics-reports/app-sessions this App Sessions report. My question is thus the following :
Does the Sessions number actually gives me the number of all sessions, or only those from opt-in users ? It says that it is based on users who have agreed to share their data with Apple and developers, so I was wondering whether or not through the use of the methods described on this page https://developer.apple.com/documentation/analytics-reports/privacy,
it meant that the data was anonymized/encoded such that it would be close to the actual Sessions number, or if it meant it only counted opt-in users to compute the Sessions numer.
Thank you for your time, I hope I made myself as clear as possible. Ask me if you want more precisions or if you don't understand my question.

I modified the system.login.screensaver rule in the authorization database to use "authenticate" instead of "use-login-window-ui" to display a custom authentication plugin view when the screensaver starts or the screen locks.
However, I noticed an issue when the "Require Password after Display is Turned Off" setting is set to 5 minutes in lock screen settings:
If I close my Mac’s lid and reopen it within 5 minutes, my authentication plugin view is displayed as expected.
However, the screen is not in a locked state—the desktop remains accessible, and the black background that typically appears behind the lock screen is missing.
This behavior differs from the default lock screen behavior, where the screen remains fully locked, and the desktop is hidden.
Has anyone encountered this issue before? Is there a way to ensure the screen properly locks when using authenticate in the screensaver rule?
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?
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 need to open p12 file from other iOS applications to import private key to my application. My app is set up to be able to open nay file with following plist
<?xml version="1.0" encoding="UTF-8"?>

But my don't appear in share dialog from Files or Mail app for example. There are however other third party apps that can accept this file. Some of them use Share extension which I don't have, but some of them don't have it as far as I can understand. At least they don't present any UI and open apps directly.
Also I've tried to specify com.rsa.pkcs-12 UTI directly but it didn't help. Also noticed that *.crt files have similar behaviour.
Am I missing something about this specific file type?
Quinn, in your post "App Groups: macOS vs iOS: Fight!", you mention that an app must meet at least one of four criteria to access an app group container without user intervention:
Your app is deployed via the Mac App Store (A).
Or via TestFlight when running on macOS 15.1 or later (B).
Or the app group ID starts with your app’s Team ID (C).
Or your app’s claim to the app group is authorised by a provisioning profile embedded in the app (D) [1].
Our app is distributed directly (Developer ID), so it doesn't meet the first two criteria. We already had the app group ID set up to match the iOS ID (without our Team ID) and changing it now would affect our users already-stored data, so criteria C isn't really an option either.
That brings us to criteria D. We've added the App Groups Capability to our App ID on the Developer site and creating a Developer ID provisioning profile with this App ID. However, for some reason the App Group Capability is not included in the provisioning profile.
How then do we go about satisfying criteria D ("your app’s claim to the app group is authorised by a provisioning profile embedded in the app (D)")?
If this is impossible, how can we migrate our user's data away from the affected container?
Hello everyone,
I'm working on a project where I intend to use Secure Enclave-based, device-bound private keys within a Webauthn flow. I have the following question:
Is it possible to generate private keys in the Secure Enclave with integrated attestation in order to reliably prove to a relying party the authenticity and uncompromised state of the key?
If so, I would appreciate details on the implementation—specifically, any prerequisites, limitations, or particular API calls and configuration options that need to be considered.
I look forward to any advice, best practices, or pointers to further documentation on this topic.
Thank you in advance for your support!
Best regards,
Alex

Hello everyone,
In my application, i have implemented authentication using ASWebauthenticationSession. However, when redirecting the user to a WKWebView, no cookies are shared, causing the session to be lost and requiring the user to log in again.
Is there a way to share cookies between the two? If not, what would be the best approach to set up authentication that ensures SSO when switching to a WebView ?
Thank you very much for your help !
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...
It would be nice if Apple / XCode would be so gracious to explore the possibility of providing the ability to include:
Code scrambling / renaming
Control-flow obfuscation
String encryption
Anti-debugging
Anti-hooking
Jailbreak detection
App integrity checks
Runtime tamper detection
That way, we could eliminate the need to settle for third-party software.
Who do we have to bribe to submit such a request and entertain such an idea?

While working with Platform SSO on macOS, I’m trying to better understand how the system handles cases where a user’s local account password becomes unsynchronized with their Identity Provider (IdP) password—for example, when the device is offline during a password change.
My assumption is that macOS may store some form of persistent token during the Platform SSO user registration process (such as a certificate or similar credential), and that this token could allow the system to unlock the user’s login keychain even if the local password no longer matches the IdP password.
I’m hoping to get clarification on the following:
Does macOS actually use a persistent token to unlock the login keychain when the local account password is out of sync with the IdP password? If so, how is that mechanism designed to work?
If such a capability exists, is it something developers can leverage to enable a true passwordless authentication experience at the login window and lock screen (i.e., avoiding the need for a local password fallback)?
I’m trying to confirm what macOS officially supports so I can understand whether passwordless login is achievable using the persistent-token approach.
Thanks in advance for any clarification.

I'm using Secure Enclave to generate and use a private key like this:
let access = SecAccessControlCreateWithFlags(nil,
kSecAttrAccessibleWhenUnlockedThisDeviceOnly,
[.privateKeyUsage, .biometryAny],
nil)
let attributes: [String: Any] = [
kSecAttrKeyType as String: kSecAttrKeyTypeECSECPrimeRandom,
kSecAttrKeySizeInBits as String: 256,
kSecAttrTokenID as String: kSecAttrTokenIDSecureEnclave,
kSecAttrAccessControl as String: access as Any,
kSecAttrApplicationTag as String: "com.example.key".data(using: .utf8)!,
kSecReturnRef as String: true
]
let privateKey = SecKeyCreateRandomKey(attributes as CFDictionary, nil)
Later, I use this key to sign a message:
let signature = SecKeyCreateSignature(privateKey, .ecdsaSignatureMessageX962SHA256, dataToSign as CFData, nil)
This prompts for biometric authentication, but shows the default system text.
How can I customize or localize the biometric prompt (e.g., title, description, button text) shown during SecKeyCreateSignature?
Thanks!
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
Hey everyone,
I'm working on a password manager app for iOS and I'm trying to implement the new iOS 18 feature that lets users enable autofill directly from within the app. I know this exists because I've seen it in action in another app. They've clearly figured it out, but I'm struggling to find any documentation or info about the specific API.
Has anyone else had any luck finding this? Any help would be greatly appreciated!
Thanks in advance!
Hello,
Is there any way to detect if the iOS screen is currently being shared via FaceTime or iPhone Mirroring?
Our application relies on this information to help ensure that users are not accessing it from one location while physically being in another.
I am currently working on Fraud System Detection that will be used by one of the financial institutions. Those tools are related to ensuring user security.
Our goal is to identify features that can trigger an early warning system for attempted fraud. We have identified three uncertain variables:
Whether the user is having a conversation while using our app,
Whether the user has specific screen sharing apps on their phone,
Whether the user has enabled VPN connection.
Here my doubts appear:
Can we check the presence of a telephone conversation if we are not a VOIP application?
Can we check the presence of installed programs using Universal Link and canOpenUrl(_:) method?
Can we read "SCOPED" key from CFNetworkCopySystemProxySettings() dictionary?
I will be glad for any advice and help.

Hello,
I'm seeking some clarification regarding the use of accessibility and input monitoring APIs in sandboxed apps that are distributed through the App Store.
I understand that accessibility permissions are generally restricted for App Store apps. However, I've seen several recently released apps request these permissions directly upon first launch. I'm aware that apps submitted prior to 2012 may have legacy access to certain APIs, but the ones I'm referring to appear to be recent - within the past year.
While it's possible these apps were approved despite the restrictions, I want to make sure I'm not overlooking something. I also came across a recent discussion on this topic, and one post in particular stood out: Link
I’d really appreciate some clarification on what's officially allowed. Specifically:
Are accessibility permissions ever allowed? If so, under what circumstances?
Is input monitoring permitted for apps on the App Store? (The referenced post says yes, but since it's from 2022, I just want to confirm)
The linked post suggests that event generation might be allowed on the App Store, though the author hadn’t explored that privilege in detail and recommended opening a DTS tech support incident. I’ve done that and have a support case open - would it be possible to take a closer look at this?
For context, my app (currently distributed outside the App Store) uses CGEventPost and CGEventCreateMouseEvent to modify mouse behavior.
Thank you
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?
I'm looking for confirmation on the security aspects of fdesetup authrestart when used on a FileVault-enabled Mac.
As I understand it, this command temporarily stores the decryption key in memory to allow the system to restart without requiring manual entry of the FileVault password. However, I have a few security-related concerns:
Storage of the Decryption Key: Where exactly is the key stored during an authenticated restart? Is it protected within the Secure Enclave (for Apple Silicon Macs) or the T2 Security Chip on Intel Macs?
Key Lifetime & Wiping: At what point is the decryption key erased from memory? Does it persist in any form after the system has fully rebooted?
Protection Against Physical Attacks: If an attacker gains physical access to the machine before the restart completes, is there any possibility that they could extract the decryption key from memory?
Cold Boot Attack Resistance: Is there any risk that advanced forensic techniques (such as freezing RAM to retain data) could be used to recover the decryption key after issuing an authenticated restart?
Malware Resistance: Could a compromised system (e.g., root access by an attacker) intercept or misuse the decryption key before the restart?
I understand that on Apple Silicon and T2-equipped Macs, FileVault keys are tied to hardware-based encryption, making unauthorized access difficult.
However, I'd like to confirm whether Authenticated Restart introduces any new risks compared to a standard FileVault-enabled boot process.
