Hi, I am developing a Platform SSO in order to have integrated with our IdP, which I am also adapting to provide the right endpoints for Platform SSO. I have a few questions about the implementation: does the client-request-id need to be present on all requests? Is it unique per request, or requests that are bound together like those requesting a nonce and those who will use that nonce should use the same client-request-id? I am not sure how the loginManager.presentRegistrationViewController works. I'd like to get the user to authenticate to my IdP before device registration. So I am not sure if I should provide my own Webview or something similar or if this method should do something for me; My idea is to request user authentication once, save the state when performing device registration, so that I avoid asking for user authentication twice when performing user registration. Is this the right way to do it? How does platform SSO handles tokens? If one application of my IdP requests the authentication on a common OIDC/OAuth2 flow, should I perform some sort of token exchange? How about SAML? Platform SSO seems to be token-centric, but how does one handle SAML flows? Is it by using WebView as well?

Hi, I am using CryptoKit in my app. I am getting an error sometimes with some users. I log the description to Firebase but I am not sure what is it exactly about.  CryptoKit.CryptoKitError error 2  CryptoKit.CryptoKitError error 3 I receive both of these errors. I also save debug prints to a log file and let users share them with me. Logs are line-by-line encrypted but after getting these errors in the app also decryption of log files doesn't work and it throws these errors too. I couldn't reproduce the same error by myself, and I can't reach the user's logs so I am a little blind about what triggers this. It would be helpful to understand what these errors mean. Thanks

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.

Hi, 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.

WebAuthn Level 3 § 6.3.2 Step 2 states the authenticator must : Check if at least one of the specified combinations of PublicKeyCredentialType and cryptographic parameters in credTypesAndPubKeyAlgs is supported. If not, return an error code equivalent to "NotSupportedError" and terminate the operation. On my iPhone 15 Pro Max running iOS 18.5, Safari + Passwords does not exhibit this behavior; instead an error is not reported and an ES256 credential is created when an RP passes a non-empty sequence that does not contain {"type":"public-key","alg":-7} (e.g., [{"type":"public-key","alg":-8}]). When I use Chromium 138.0.7204.92 on my laptop running Arch Linux in conjunction with the Passwords app (connected via the "hybrid" protocol), a credential is not created and instead an error is reported per the spec.

Hi community, I'm wondering how can I request the permission of "System Audio Recording Only" under the Privacy & Security -> Screen & System Audio Recording via swift? Did a bunch of search but didn't find good documentation on it. Tried another approach here https://github.com/insidegui/AudioCap/blob/main/AudioCap/ProcessTap/AudioRecordingPermission.swift which doesn't work very reliably.

In some crashlog files, there are additional pieces of information related to codesigning. I can understand what most of themcorresponds to (ID, TeamID, Flags, Validation Category). But there is one I have some doubt about: Trust Level. As far as I can tell (or at least what Google and other search engines say), this is an unsigned 32 bit integer that defines the trust level with -1 being untrusted, 0, being basically an Apple executable and other potential bigger values corresponding to App Store binaries, Developer ID signature, etc. Yet, I'm not able to find a corresponding detailed documentation about this on Apple's developer website. I also had a look at the LightweightCodeRequirements "include" file and there does not seem to be such a field available. [Q] Is there any official documentation listing the different values for this trust level value and providing a clear description of what it corresponds to?

Step1. Update system.login.screensaver authorizationdb rule to use “authenticate-session-owner-or-admin”( to get old SFAutorizationPluginView at Lock Screen ). Here I will use my custom authorization plugin. Step 2. Once the rule is in place, logout and login, now click on Apple icon and select “Lock Screen”. Is there a way programmatically to update the Lock Icon and the test getting displayed on the first Unlock screen? When I write a custom authorisation plug-in, I am getting control of the text fields and any consecutive screen I add from there on. But all I want is to update the lock icon and text fields on 1st unlock display itself. Can you please suggest how I can achieve this? Here is the screenshot with marked areas I am looking control for.

Hi all, I’m building a macOS-native C++ trading bot, compiled via Xcode. It sends REST API requests to a crypto exchange (Bitvavo) that require HMAC-SHA256 signatures using a pre-sign string (timestamp + method + path + body) and an API secret. Here’s the issue: • The exact same pre-sign string and API secret produce valid responses when signed using Python (hmac.new(secret, msg, hashlib.sha256)), • But when I generate the HMAC signature using C++ (HMAC(EVP_sha256, ...) via OpenSSL), the exchange returns an invalid signature error. Environment: • Xcode 15.3 / macOS 14.x • OpenSSL installed via Homebrew • HMAC test vectors match Python’s output for basic strings (so HMAC lib seems correct) Yet when using the real API keys and dynamic timestamped messages, something differs enough to break verification — possibly due to UTF-8 encoding, memory alignment, or newline handling differences in the Xcode C++ runtime? Has anyone experienced subtle differences between Python and C++ HMAC-SHA256 behavior when compiled in Xcode? I’ve published a GitHub repo for reproducibility: 🔗 https://github.com/vanBaardewijk/bitvavo-cpp-signature-test Thanks in advance for any suggestions or insights. Sascha

Hi Apple, Currently we want to have enhancement for SMS OTP that we want to implement OTP Autofill, But after do some research we're stuck with option that the OTP only show in keyboard suggestion, is there any way for making OTP is automatically filled without user have to click the keyboard suggestion when receiving the SMS. Thanks Best Regards, Admiral Sultano Harly.

For context, my company develops a data loss prevention (DLP) product. Part of our functionality is the ability to detect sensitive data being pasted into a web browser or cloud-based app. The AppKit release notes for April 2025 document an upcoming “macOS pasteboard privacy” feature, which will presumably ship in macOS 26. Using the user default setting “EnablePasteboardPrivacyDeveloperPreview” documented in the release notes, I tested our agent under macOS 15.5, and encountered a modal alert reading " is trying to access the pasteboard" almost immediately, when the program reads the General pasteboard to scan its contents. Since our product is aimed at enterprise customers (and not individual Mac users), I believed Apple would implement a privacy control setting for this new feature. This would allow our customers to push a configuration profile via MDM, with the “Paste from Other Apps” setting for our application preset to “Allow”, so that they can install our product on their endpoints without manual intervention. Unfortunately, as of macOS 26 beta 4 (25A5316i), there does not seem to be any such setting documented under Device Management — for example in PrivacyPreferencesPolicyControl.Services, which lists a number of similar settings. Without such a setting available, a valuable function of our product will be effectively crippled when macOS 26 is released. Is there such a setting (that I've overlooked)? If not, allow me to urge Apple to find the resources to implement one, so that our customers can preset “Paste from Other Apps” to “Allow” for our application.

We’ve identified an issue in our app where, upon clicking the "Call Customer Center" button, users are unexpectedly shown a logo and message option on a native pop-up window. However, this wasn't the case before, and it should only display a phone number to dial, which was given inside our code. This is incorrect and misleading for our users, as: We are a Canadian-based service and have no affiliation with US messaging chat. The messaging feature was never enabled or intended for our app. Our app should only initiate a phone call to our customer support center — no messages or branding from third parties should appear

I'm trying to add a generic password to the keychain and get back the persistent ID for it, and give it .userPresence access control. Unfortunately, if I include that, I get paramError back from SecItemAdd. Here's the code: @discardableResult func set(username: String, hostname: String?, password: String, comment: String? = nil) throws -> PasswordEntry { // Delete any existing matching password… if let existing = try? getEntry(forUsername: username, hostname: hostname) { try deletePassword(withID: existing.id) } // Store the new password… var label = username if let hostname { label = label + "@" + hostname } var item: [String: Any] = [ kSecClass as String : kSecClassGenericPassword, kSecAttrDescription as String : "TermPass Password", kSecAttrGeneric as String : self.bundleID.data(using: .utf8)!, kSecAttrLabel as String : label, kSecAttrAccount as String : username, kSecValueData as String : password.data(using: .utf8)!, kSecReturnData as String : true, kSecReturnPersistentRef as String: true, ] if self.synchronizable { item[kSecAttrSynchronizable as String] = kCFBooleanTrue! } if let hostname { item[kSecAttrService as String] = hostname } if let comment { item[kSecAttrComment as String] = comment } // Apply access control to require the user to prove presence when // retrieving this password… var error: Unmanaged<CFError>? guard let accessControl = SecAccessControlCreateWithFlags(nil, kSecAttrAccessibleWhenUnlockedThisDeviceOnly, .userPresence, &error) else { let cfError = error!.takeUnretainedValue() as Error throw cfError } item[kSecAttrAccessControl as String] = accessControl item[kSecAttrAccessible as String] = kSecAttrAccessibleWhenUnlockedThisDeviceOnly var result: AnyObject! let status = SecItemAdd(item as CFDictionary, &result) try Errors.throwIfError(osstatus: status) load() guard let secItem = result as? [String : Any], let persistentRef = secItem[kSecValuePersistentRef as String] as? Data else { throw Errors.malformedItem } let entry = PasswordEntry(id: persistentRef, username: username, hostname: hostname, password: password, comment: comment) return entry } (Note that I also tried it omitting kSecAttrAccessible, but it had no effect.) This code works fine if I omit setting kSecAttrAccessControl. Any ideas? TIA!

I have 2 basic questions related to Launch Constraints: [Q1] Are Launch Constraints supposed to work when SIP is disabled? From what I'm observing, when SIP is disabled, Launch Constraints (e.g. Launch Constraint Parent Process) are not enforced. I can understand that. But it's a bit confusing considering that the stack diagram in the WWDC 2023 session is placing the 'Environment Constraints' block under SIP, not above. Also the documentation only mentions SIP for the 'is-sip-protected' fact. [Q2] Is the SpawnConstraint key in legacy launchd plist files (i.e. inside /Library/Launch(Agents|Daemons)) officially supported? From what I'm seeing, it seems to be working when SIP is enabled. But the WWDC session and the documentation don't really talk about this case.

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.

In the hopes of saving others time, the updated demo project (i.e. the new Shiny) can be found from the video 'Resources' section under 'Performing fast account creation with passkeys'. The beta documentation can also be found from there. All of the new functionality is available only on *OS 26 at this time.

I am trying to setup remote Java debugging between two machines running macOS (15.6 and 26). I am able to get the Java program to listen on a socket. However, I can connect to that socket only from the same machine, not from another machine on my local network. I use nc to test the connection. It reports Connection refused when trying to connect from the other machine. This issue sounds like it could be caused by the Java program lacking Local Network system permission. I am familiar with that issue arising when a program attempts to connect to a port on the local network. In that case, a dialog is displayed and System Settings can be used to grant Local Network permission to the client program. I don't know whether the same permission is required on the program that is receiving client requests. If it is, then I don't know how to grant that permission. There is no dialog, and System Settings does not provide any obvious way to grant permission to a program that I specify. Note that a Java application is a program run by the java command, not a bundled application. The java command contains a hard-wired Info.plist which, annoyingly, requests permission to use the microphone, but not Local Network access.

Hi everyone, I have a macOS application that uses Screen Recording permission. I build my app with an adhoc signature (not with a Developer ID certificate). For example, in version 1.0.0, I grant Screen Recording permission to the app. Later, I build a new version (1.1.0) and update by dragging the new app into the Applications folder to overwrite the previous one. However, when I launch the updated app, it asks for Screen Recording permission again, even though I have already granted it for the previous version. I don’t fully understand how TCC (Transparency, Consent, and Control) determines when permissions need to be re-granted. Can anyone explain how TCC manages permissions for updated builds, especially with adhoc signatures? Is there any way to retain permissions between updates, or any best practices to avoid having users re-authorize permissions after every update?

Hi, I'm looking at adding App Attest to an app, and I think I understand the mechanics of the attestation process, but I'm having trouble figuring out how development and testing are supposed to work. Two main questions: The "App Attest Environment" -- the documentation says that attestation requests made in the .development sandbox environment don't affect the app's risk metrics, but I'm not sure how to actually use this sandbox. My understanding is that one of the things App Attest does is to ensure that your app has been appropriately signed by the App Store, so it knows that it hasn't been tampered with. But the docs say that App Store builds (and Test Flight and Developer Enterprise Program) always use the .production environment. Does App Attest actually work for local developer-build apps if you have this entitlement set? Presumably only on hardware devices since it requires the Secure Enclave? Does our headend have to do something different when verifying the public key and subsequent attested requests for an app that's using the .development sandbox? The docs do mention that a headend server should potentially track two keys per device/user pair so that it can have a production and development key. How does the headend know if a key is from the sandbox environment? Thanks!

Has anybody else experienced something similar? This is on the login screen. I call update() and it doesn't call me back with view() 2025-08-21 17:04:38.669 Db SecurityAgentHelper-arm64[1134:2df1] [***:LoginView] calling update() Then silence...
