When I reboot my iPhone 14 pro with Live Activity started, Keychase information disappears.
So there is a problem that I have to sign-in again when I enter the app.
There is no problem rebooting the iPhone without Live Activity.
iOS17 didn't have this problem.

I'm developing an authorization plugin for macOS and encountering a problem while trying to store a password in the system keychain (file-based keychain). The error message I'm receiving is:
Failed to add password: Write permissions error.
Operation status: -61
Here’s the code snippet I’m using:
import Foundation
import Security
@objc class KeychainHelper: NSObject {
@objc static func systemKeychain() -> SecKeychain? {
var searchListQ: CFArray? = nil
let err = SecKeychainCopyDomainSearchList(.system, &searchListQ)
guard err == errSecSuccess else {
return nil
}
let searchList = searchListQ! as! [SecKeychain]
return searchList.first
}
@objc static func storePasswordInSpecificKeychain(service: String, account: String, password: String) -> OSStatus {
guard let systemKeychainRef = systemKeychain() else {
print("Error: Could not get a reference to the system keychain.")
return errSecNoSuchKeychain
}
guard let passwordData = password.data(using: .utf8) else {
print("Failed to convert password to data.")
return errSecParam
}
let query: [String: Any] = [
kSecClass as String: kSecClassGenericPassword,
kSecAttrService as String: service,
kSecAttrAccount as String: account,
kSecValueData as String: passwordData,
kSecUseKeychain as String: systemKeychainRef // Specify the System Keychain
]
let status = SecItemAdd(query as CFDictionary, nil)
if status == errSecSuccess {
print("Password successfully added to the System Keychain.")
} else if status == errSecDuplicateItem {
print("Item already exists. Consider updating it instead.")
} else {
print("Failed to add password: \(SecCopyErrorMessageString(status, nil) ?? "Unknown error" as CFString)")
}
return status
}
}
I am callling storePasswordInSpecificKeychain through the objective-c code. I also used privileged in the authorizationDb (system.login.console).
Are there specific permissions that need to be granted for an authorization plugin to modify the system keychain?
I am currently implementing an authentication function using ASWebAuthenticationSession to log in with my Instagram account.
I set a custom scheme for the callbackURLScheme, but
In the Instagram redirect URL
I was told I can't use a custom scheme.
What should I do with the callbackURLScheme of the ASWebAuthenticationSession in this case?
I've written a little utility targeting Mac, for personal use. In it, I need to be able to select a file from an arbitrary location on my drive.
I have the "user selected file" entitlement added, and I have added my application to "Full Disk Access." But I still get a permissions error when I select a file with the file-open dialog (via .fileImporter).
I dragged the application from the Xcode build directory to Applications before adding it to Full Disk Access. Any ideas?
Having trouble decrypting a string using an encryption key and an IV.
var key: String
var iv: String
func decryptData(_ encryptedText: String) -> String?
{
if let textData = Data(base64Encoded: iv + encryptedText) {
do {
let sealedBox = try AES.GCM.SealedBox(combined: textData)
let key = SymmetricKey(data: key.data(using: .utf8)!)
let decryptedData = try AES.GCM.open(sealedBox, using: key)
return String(data: decryptedData, encoding: .utf8)
} catch {
print("Decryption failed: \(error)")
return nil
}
}
return nil
}
Proper coding choices aside (I'm just trying anything at this point,) the main problem is opening the SealedBox. If I go to an online decryption site, I can paste in my encrypted text, the encryption key, and the IV as plain text and I can encrypt and decrypt just fine.
But I can't seem to get the right combo in my Swift code. I don't have a "tag" even though I'm using the combined option. How can I make this work when all I will be receiving is the encrypted text, the encryption key, and the IV. (the encryption key is 256 bits)
Try an AES site with a key of 32 digits and an IV of 16 digits and text of your choice. Use the encrypted version of the text and then the key and IV in my code and you'll see the problem. I can make the SealedBox but I can't open it to get the decrypted data. So I'm not combining the right things the right way. Anyone notice the problem?

I've made a simple command line app that requires Screen recording permission.
When I ran it from Xcode, it prompts for a permission and once I allowed it from the settings, it runs well.
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <CoreGraphics/CGDisplayStream.h>
int main() {
printf("# Start #\n");
if (CGPreflightScreenCaptureAccess()) {
printf("# Permitted.\n");
} else {
printf("# Not permitted.\n");
if (CGRequestScreenCaptureAccess() == false) {
printf("# CGRequestScreenCaptureAccess() returning false\n");
}
}
size_t output_width = 1280;
size_t output_height = 720;
dispatch_queue_t dq = dispatch_queue_create("com.domain.screengrabber", DISPATCH_QUEUE_SERIAL);
CGError err;
CGDisplayStreamRef sref = CGDisplayStreamCreateWithDispatchQueue(
1,
output_width,
output_height,
'BGRA',
NULL,
dq,
^(
CGDisplayStreamFrameStatus status,
uint64_t time,
IOSurfaceRef frame,
CGDisplayStreamUpdateRef ref
) {
printf("Got frame: %llu, FrameStatus:%d \n", time, status);
}
);
err = CGDisplayStreamStart(sref);
if (kCGErrorSuccess != err) {
printf("Error: failed to start streaming the display. %d\n", err);
exit(EXIT_FAILURE);
}
while (true) {
usleep(1e5);
}
CGDisplayStreamStop(sref);
printf("\n\n");
return 0;
}
Now I want to execute this from terminal, so I went to the build folder and
typed the app name.
cd /Users/klee/Library/Developer/Xcode/DerivedData/ScreenStreamTest-ezddqbkzhndhakadslymnvpowtig/Build/Products/Debug
./ScreenStreamTest
But I am getting following output without any prompt for permission.
# Start #
# Not permitted.
# CGRequestScreenCaptureAccess() returning false
Error: failed to start streaming the display. 1001
Is there a something I need to consider for this type of command line app?
Hello developers,
I'm currently working on an authorization plugin for macOS. I have a custom UI implemented using SFAuthorizationPluginView, which prompts the user to input their password. The plugin is running in non-privileged mode, and I want to store the password securely in the system keychain.
However, I came across an article that states the system keychain can only be accessed in privileged mode. At the same time, I read that custom UIs, like mine, cannot be displayed in privileged mode.
This presents a dilemma:
In non-privileged mode: I can show my custom UI but can't access the system keychain.
In privileged mode: I can access the system keychain but can't display my custom UI.
Is there any workaround to achieve both? Can I securely store the password in the system keychain while still using my custom UI, or am I missing something here?
Any advice or suggestions are highly appreciated!
Thanks in advance! 😊
I am trying to send email from our internal server. We are using gmail as smtp client. Gmail is bound to a domain hosted on squarespace. I have all the required DNS records - DKIM, DMARC, SPF configured in squarespace. In the Apple Developer Portal, I have also added allowed domains and email addresses in the Sign In with Apple settings. SPF verification passed.
The problem is that emails sent to @privaterelay.appleid.com are not reaching the final recipient. On our end, the emails are sent and there are no errors.
In the email signature the DKIM domain and the domain in the From: address match completely. Domain on tools like mxtoolbox passes all checks.
Also, there is no response from the gmail server that the email was not delivered. To all other emails the emails are being sent with no problems. Please help me figure this out, maybe I am missing something.
When we develop 'Sign in with Apple' function on our app, we visited https://appleid.apple.com to verify the account. However, appleid.apple.com is mapped to an American IP, and it is not suitable for our app which is operated in China. I wonder whether there is a China Mainland IP available for the verification? Thanks very much.
We have a macOS app that has a Photos Extension, which shares documents with the app via an app group container. Historically we used to have an iOS-style group identifier (group.${TeamIdentifier}${groupName}), because we were lead by the web interface in the developer portal to believe this to be the right way to name groups.
Later with the first macOS 15 betas last year there was a bug with the operating system warning users, our app would access data from different apps, but it was our own app group container directory.
Therefore we added a macOS-style group identifier (${TeamIdentifier}${groupName}) and wrote a migration of documents to the new group container directory.
So basically we need to have access to these two app group containers for the foreseeable future.
Now with the introduction of iOS-style group identifiers for macOS, Xcode Cloud no longer archives our app for TestFlight or AppStore, because it complains:
ITMS-90286: Invalid code signing entitlements - Your application bundle’s signature contains code signing entitlements that aren’t supported on macOS. Specifically, the “[group.${TeamIdentifier}${groupName}, ${TeamIdentifier}${groupName}]” value for the com.apple.security.application-groups key in isn’t supported. This value should be a string or an array of strings, where each string is the “group” value or your Team ID, followed by a dot (“.”), followed by the group name. If you're using the “group” prefix, verify that the provisioning profile used to sign the app contains the com.apple.security.application-groups entitlement and its associated value(s).
We have included the iOS-style group identifier in the provisioning profile, generated automatically, but can't do the same for the macOS-style group identifier, because the web interface only accepts identifiers starting with "group".
How can we get Xcode Cloud to archive our app again using both group identifiers?
Thanks in advance
Hello --
I am developing an Authentication Plug-in for the purpose of invoking login with no user interaction (headless).
There seems to be sufficient documentation and sample code on how to implement a plug-in and mechanism, and debug the same, which is great. What I am trying to understand is exactly how to modify the login right (system.login.console) in order to accomplish my goal.
Question 1:
I had the idea of installing my mechanism as the first mechanism of the login right, and when invoked to set the username and password into the engine’s context, in the belief that this would negate the system from needing to display the login screen. I didn’t modify or remove any other mechanisms. This did not work, in the sense that the login screen was still shown. Should this work in theory?
Question 2:
I then tried modifying the login right to remove anything that interacted with the user, leaving only the following:
<array>
<string>builtin:prelogin</string>
<string>builtin:login-begin</string>
<string>builtin:forward-login,privileged</string>
<string>builtin:auto-login,privileged</string> <string>MyAuthPlugin:customauth,privileged</string>
<string>PKINITMechanism:auth,privileged</string>
<string>builtin:login-success</string>
<string>HomeDirMechanism:login,privileged</string>
<string>HomeDirMechanism:status</string>
<string>MCXMechanism:login</string>
<string>CryptoTokenKit:login</string>
</array>
The mechanisms I removed were:
<string>builtin:policy-banner</string>
<string>loginwindow:login</string>
<string>builtin:reset-password,privileged</string>
<string>loginwindow:FDESupport,privileged</string>
<string>builtin:authenticate,privileged</string>
<string>loginwindow:success</string>
<string>loginwindow:done</string>
In place of builtin:authenticate I supplied my own mechanism to verify the user’s password using OD and then set the username and password in the context. This attempt appears to have failed quite badly, as authd reported an error almost immediately (I believe it was related to the AuthEngine failing to init).
There’s very little information to go on as to what each of these mechanisms do, and which are required, etc.
Am I on the wrong track in attempting this? What would be the correct approach?
I'm seeing some odd behavior which may be a bug. I've broken it down to a least common denominator to reproduce it. But maybe I'm doing something wrong.
I am opening a file read-write. I'm then mapping the file read-only and private:
void* pointer = mmap(NULL, 17, PROT_READ, MAP_FILE | MAP_PRIVATE, fd, 0);
I then unmap the memory and close the file. After the close, eslogger shows me this:
{"close":{"modified":false,[...],"was_mapped_writable":false}}
Which makes sense.
I then change the mmap statement to:
void* pointer = mmap(NULL, 17, PROT_READ, MAP_FILE | MAP_SHARED, fd, 0);
I run the new code and and the close looks like:
{"close":{"modified":false, [....], "was_mapped_writable":true}}
Which also makes sense.
I then run the original again (ie, with MAP_PRIVATE vs. MAP_SHARED) and the close looks like:
{"close":{"modified":false,"was_mapped_writable":true,[...]}
Which doesn't appear to be correct.
Now if I just open and close the file (again, read-write) and don't mmap anything the close still shows:
{"close":{ [...], "was_mapped_writable":true,"modified":false}}
And the same is true if I open the file read-only.
It will remain that way until I delete the file. If I recreate the file and try again, everything is good until I map it MAP_SHARED.
I tried this with macOS 13.6.7 and macOS 15.0.1.
Hi everyone,
I am trying to use ASWebAuthenticationSession to authorize user using OAuth2.
Service Webcredentials is set.
/.well-known/apple-app-site-association file is set.
When using API for iOS > 17.4 using new init with callback: .https(...) everything works as expected, however i cannot make .init(url: ,callbackURLScheme: ....) to work.
How can i intercept callback using iOS <17.4?
Do I really need to use universal links?
callbackURL = https://mydomain.com/auth/callback
We run simple iOS Swift code triggered by a remote notification:
UserDefaults.standard.set("key", forKey: "value")
It runs fine when the app is active or inactive, but when the device is closed/locked and the code is triggered, we see a warning in Xcode:
Couldn't write values for keys (
key
) in CFPrefsPlistSource<0x3018802d0> (Domain: com.example, User: kCFPreferencesCurrentUser, ByHost: No, Container: (null), Contents Need Refresh: No): Path not accessible
Not updating lastKnownShmemState in CFPrefsPlistSource<0x3018802d0> (Domain: com.example, User: kCFPreferencesCurrentUser, ByHost: No, Container: (null), Contents Need Refresh: No): 767 -> 767
The issue is that there seems to be no way to catch that warning. The value is set, when it's re-read the value is correct. But the value is never written to disk, so after an app restart/update the value is gone, potentially has an old wrong value.
This code runs without any interruption, it's just showing the warning on iOS 17.7.1 on iPad:
UserDefaults.standard.set("key", forKey: "value")
UserDefaults.standard.synchronize()
print("value: \(UserDefaults.standard.string(forKey: "key"))")
Should there not be a way to catch this, so the code can act accordingly to the circumstances? It would be good to know inside the code that the value is not persisted. I would expect that an exception is generated somewhere which can be caught.
It seems .completeFileProtectionUntilFirstUserAuthentication enables files to be written to disk while the device is closed/locked, can something similar be used for UserDefaults.standard?
Hello,
I started looking to implement SSO with Apple on my website using this tutorial : https://developers.appcharge.com/docs/apple-sso-login
However, when going to https://developer.apple.com/account/resources/identifiers/list
to generate a new Key, i'm getting the error :
"Unable to find a team with the given Team ID 'XXXXXXXX' to which you belong. Please contact Apple Developer Program Support".
It was a breeze to implement Google SSO, but not for Apple.
I can't find much help online, could you guide me ?

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!
Hi,
ASCredentialProvider had been almost identically implemented on both iOS and macOS so far, but the ProvidesTextToInsert feature was only added to iOS. It would have been a crucial point to make Credential Providers available in all textfields, without users having to rely on developers correctly setting roles for their Text Fields.
It's right now impossible to paste credentials into Notes, or some other non-password text box both in web and desktop apps for example, in a seamless, OS-supported way without abusing Accessibility APIs which are understandably disallowed in Mac App Store apps. Or just pasting an SSH key, or anything. On macOS this has so many possibilities. It could even have a terminal command.
It's even more interesting that "Passwords..." is an option in macOS's AutoFill context menu, just like on iOS, however Credential Providers did not gain this feature on macOS, only on iOS.
Is this an upcoming feature, or should we find alternatives? Or should I file a feature request? If it's already in the works, it's pointless to file it.
In the FAQ about Local Network, a lot of topics are covered but, unless I missed something, I didn't see the topic of MDMs being covered.
[Q] Could the FAQ be updated to cover whether it is possible to grant this Local Network permission through a configuration profile?
The answer, based on google searches and different forums, seems to be a negative. It seems a bit strange considering that this feature has been available on iOS for at least 3 years.
Anyway, even if it is not possible, it would be useful to add in the FAQ that this is not possible.
Is there a way to know the event of user unlocking on iOS Device in Application?
Hi,
I develop a Mac application, initially on Catalina/Xcode12, but I recently upgrade to Monterey/Xcode13. I'm about to publish a new version: on Monterey all works as expected, but when I try the app on Sequoia, as a last step before uploading to the App Store, I encountered some weird security issues:
The main symptom is that it's no longer possible to save any file from the app using the Save panel, although the User Select File entitlement is set to Read/Write.
I've tried reinstalling different versions of the app, including the most recent downloaded from TestFlight. But, whatever the version, any try to save using the panel (e.g. on the desktop) results in a warning telling that I don't have authorization to record the file to that folder.
Moreover, when I type spctl -a -t exec -v /Applications/***.app in the terminal, it returns rejected, even when the application has been installed by TestFlight.
An EtreCheck report tells that my app is not signed, while codesign -dv /Applications/***.app returns a valid signature. I'm lost...
It suspect a Gate Keeper problem, but I cannot found any info on the web about how this system could be reset. I tried sudo spctl --reset-default, but it returns This operation is no longer supported...
I wonder if these symptoms depend on how the app is archived and could be propagated to my final users, or just related to a corrupted install of Sequoia on my local machine. My feeling is that a signature problem should have been detected by the archive validation, but how could we be sure?
Any idea would be greatly appreciated, thanks!
