I will post my app xyz.app uses XY swift package
this swift package is a wrapper for XYSDK.xcframework
XYSDK.xcframework written in c++ and app running on arm64 macos and iphones succesfully.
I got this error when i want to distribute it.
Currently i sign .framework for ios with Apple Distribution Certificate
and same certificate for macos framework there is no other signing step for swift package or xcframework
other than that when i want to archive it validates succesfully.
Exporting step shows that app has signed, has provisining profile.
but .framework is only signed has no provisioning profile.
Also one point i see:
i have one target named xyz and its Frameworks, Lİbraries and Embedded Context has only XY package but Embed part has no option like embed and sign etc. Blank.
I need more info about what am i doing wrong in which step ?
I am stuck and can not move any further like weeks
Error Detail:
Invalid Signature. The binary with bundle identifier XYSDK at path “xyz.app/Frameworks/XYSDK.framework” contains an invalid signature. Make sure you have signed your application with a distribution certificate, not an ad hoc certificate or a development certificate. Verify that the code signing settings in Xcode are correct at the target level (which override any values at the project level). Additionally, make sure the bundle you are uploading was built using a Release target in Xcode, not a Simulator target. If you are certain your code signing settings are correct, choose “Clean All” in Xcode, delete the “build” directory in the Finder, and rebuild your release target.

I have a macOS application that was previously distributed under my personal Apple Developer account using a Developer ID certificate. We’ve recently transitioned distribution to our company’s Apple Developer account.
The app’s bundle identifier has been successfully transferred, and I’ve signed a new build of the app using the company’s Developer ID certificate. The app installs and runs correctly under the new signature. However, I’ve encountered a problem: the app is no longer able to access previously granted permissions (e.g., Screen Recording, System Audio Recording, and Input Monitoring). Furthermore, it cannot re-prompt for these permissions because they appear as already granted in System Settings.
From what I understand, this issue is due to the change in the code signing identity. Specifically, the designated requirements used by macOS to identify an app have changed, so the system no longer associates the new version of the app with the previously granted permissions (as outlined in Apple's Technical Note TN3127).
The only workaround I’ve found so far is to manually reset the app's permissions using Terminal commands (e.g., tccutil reset), but this is not something we can reasonably ask end users to do.
Question:
Is there a recommended or supported approach to either preserve permissions when changing Developer ID identities, or programmatically trigger a permissions reset for existing users? We're looking for a seamless solution that doesn't degrade user experience.

My app designer cannot sign his code changes. He says the only way he can sign his code is for me to give him my Admin privileges. I have revoked and recreated my certificate, hoping to get a private passkey, but there was no private passkey issued with the certificate. Help, please?

Hello Quinn and Apple Developer Support,
We are encountering an issue where our notarization queue appears to be stuck, and we would greatly appreciate your help.
A few days ago, we assisted another team by submitting their app for notarization using our own Apple Developer account, because their own notarization attempts were getting stuck. However, the submission we made for them under our account has now been stuck in the “In Progress” state for about 5 days.
Later, their own submission (using their account) was rejected after 2–3 days, but our submission for them (under our account) has never completed.
Since then, all our subsequent notarization requests have also remained “In Progress”, which strongly suggests that the stuck submission is blocking our entire notarization queue.
Here are the details from our submission history:
xcrun notarytool history --apple-id "xxx" --team-id "xxx" --password "xxx"
Partial results:
id: 0bafa66f-4f47-4327-811f-a05481be5d0b status: In Progress
id: 2d00b75a-a17a-44fc-afa1-71e0e39ec2cd status: In Progress
The first ID is our own app’s submission.
The second ID belongs to the submission we made for the other team.
Both have been stuck in “In Progress” for several days, which seems abnormal.
Could you please help us clear or reset the notarization queue for our account so that we can continue submitting our own apps?
Thank you very much for your time and assistance!
Best regards,
gongcj

I’m unable to notarize the executable and the .app — the status has been showing “In Progress” for over an hour. Upon checking the xcrun logs, it indicates that the submission ID was not received. I also noticed there’s an Apple Developer Service outage reported since October 8, 2025. Could you please let me know when this outage is expected to be resolved? It would be very helpful.
Hello everyone,
I'm hoping to find a solution for a critical issue that is blocking my app's submission to the App Store.
My app uses the Screen Time API and therefore has a main app and a DeviceActivityMonitor extension.
The main app has been successfully granted the Family Controls (Distribution) entitlement. However, the DeviceActivityMonitor extension is stuck with only the Family Controls (Development) entitlement.
This mismatch causes my build to fail during the archive/distribution process with the error:
"Provisioning profile failed qualification. Profile doesn't support Family Controls (Development)."
This is a hard blocker, as the extension is a mandatory part of the API. I have already filled out the entitlement request form and also contacted Developer Support (Case #102666581576), who confirmed they could not assist and directed me here.
My question is:
What is the correct procedure to escalate or resolve the issue of a required extension not receiving the distribution-level Family Controls entitlement after the main app has already been approved?
Has anyone else encountered this specific "Development" vs. "Distribution" mismatch and found a definitive way to resolve it? Any guidance would be greatly appreciated.
Thank you!
Hi guys,
I am new to publishing apps on Apple Store. I used python, pyside6, torch, pyinstaller to build an app for Apple Store.
For codesigning, I used the correct "Developer ID Application" to sign the code. When I validate the .app file (codesign -vv --strict ), I got the following
my_app.app: valid on disk
my_app.app: satisfies its Designated Requirement
Next, I used ditto to "ditto -c -k --sequesterRsrc --keepParent my_app.app my_app.zip" to zip it.
Then, I submitted this my_app.zip file for notarization with "xcrun notarytool submit ..." and got the following "accepted" message.
Received new status: Accepted
Current status: Accepted...............
[20:08:54.530Z] Info [API] Submission in terminal status: Accepted
Processing complete
After that, I want to staple it with "xcrun stapler staple my_app.app", but I got the following
Could not validate ticket for my_app.app
The staple and validate action failed! Error 65.
To further investigate it, I ran "spctl -a -vvv my_app.app" and got
my_app.app: rejected
source=Unnotarized Developer ID
origin=Developer ID Application...
I don't know why this would happen after notarization accepted. Could someone help me understand this issue? Thanks!
My notary service has been stuck for more than 5 hours. Is it because i am a new user or there is an notary service outage.

Good afternoon,
Our team is currently developing a mobile application that includes video call functionality, and we are seeking the optimal approach to enable incoming calls on iOS devices.
Ideally, we would like calls to be delivered even when the app is completely closed or after the device is restarted. As I understand it, this may require obtaining VoIP permissions; otherwise, calls may only work when the app is open or running in the background.
I would appreciate it if you could confirm my understanding and advise me on the steps or requirements for obtaining the appropriate permissions.
Currently, when I try to launch the app in XCode, I see an error (screenshot).
I've developed a Mac app distributed through the App Store that uses NSAppleScript to control Spotify and Apple Music. I'm experiencing inconsistent behavior with automation permission prompts that's affecting user experience.
Expected Behavior:
When my app first attempts to send Apple Events to Spotify or Apple Music, macOS should display the automation permission prompt, and upon user approval, the app should appear in System Preferences > Security & Privacy > Privacy > Automation.
Actual Behavior:
Initial permission prompts work correctly when both apps are actively used after my app download. If a user hasn't launched Spotify/Apple Music for an extended period, the permission prompt fails to appear when they later open the music app. The music app doesn't appear in the Automation privacy pane too. Once this happens, permission prompts never trigger again for that app
Steps to Reproduce:
Fresh install of my app
Don't use Spotify for several days/weeks
Launch Spotify
Trigger Apple Events from my app to Spotify
No permission prompt appears, app doesn't show in Automation settings
If you're using Apple Music during this time it runs without any problems.
Troubleshooting Attempted:
Used tccutil reset AppleEvents [bundle-identifier] - no effect
Verified target apps are fully launched before sending Apple Events
Tried different AppleScript commands to trigger permissions
Problem occurs inconsistently across different Macs
Technical Details:
macOS 13+ support
Using standard NSAppleScript with simple commands like "tell application 'Spotify' to playpause"
App Store distribution (no private APIs)
Issue affects both Spotify and Apple Music but seems more prevalent with Apple Music
Questions:
Is there a reliable way to programmatically trigger the automation permission prompt?
Are there timing dependencies for when macOS decides to show permission prompts?
Could app priority/usage patterns affect permission prompt behavior?
I use MediaManager to run the functions and initialize it on AppDidFinishLaunching method and start monitoring there.
Any insights or workarounds would be greatly appreciated. This inconsistency is affecting user onboarding and app functionality.
Hi everyone,
I am trying to generate an .ipa file for my .NET MAUI (net9.0-ios) application, but every attempt fails with the same codesigning error. I have tried multiple approaches, including building from Windows paired to macOS, and directly building through the macOS terminal, but nothing is working.
Below are the exact steps I followed:
Steps I Performed
1.>Generated the Apple Development certificate using Keychain Access on macOS.
2.>Added that certificate into my developer account and created the corresponding provisioning profile.
3.>Created an App ID, attached the App ID to the provisioning profile, and downloaded it.
4.>Added the provisioning profile into Xcode.
Verified that the certificate is correctly visible in Keychain Access (private key available).
Attempted to build/publish the MAUI app to generate the .ipa file.
Issue
Whenever I run the publish command or build via Windows/macOS, codesigning fails with the following error:
/usr/bin/codesign exited with code 1:
Frameworks/libSkiaSharp.framework: replacing existing signature
Warning: unable to build chain to self-signed root for signer "Apple Development: Created via API (8388XAA3RT)"

Warning: unable to build chain to self-signed root for signer "Apple Development: Created via API (8388XAA3RT)"
PCS_EmpApp.app: errSecInternalComponent
Build failed with 4 error(s) and 509 warning(s)
Environment
.NET: 9.0
MAUI: latest tools
Xcode: 26.0.1
macOS: 26.0.1
Building for ios-arm64 (device)
What I suspect
It looks like the signer certificate might not be trusted, or the certificate chain cannot connect to an Apple root CA. But the certificate was created using the Developer website and appears valid.
Need Help With
Why is codesign unable to build the certificate chain?
Do I need a different type of certificate? (App Store / Distribution vs Development?)
How can I successfully generate the .ipa file?
Any guidance will be greatly appreciated. Thank you!

Hello,
I have created multiple Developer ID Application and Developer ID Installer certificates across different Apple OS versions without keeping the Certificate Signing Requests (CSR).
As I’m not very experienced with Apple’s system, I made this mistake and now I am unable to create new certificates because I have reached the maximum number of certificates allowed.
I develop software based on Electron and have been building and signing my applications with electron-builder, integrating the app signing needed to submit the app to the Apple Store via Transporter.
Here is the relevant portion of my package.json build config:
"mac": {

}
Currently, I have recreated the Mac Developer Application and Mac Developer Installer certificates, but without valid Developer ID Installer and Developer ID Application certificates, I always get this error during build:

From my understanding, the system cannot find a valid Developer ID Application identity for signing. The existing certificates all show the CSSMERR_TP_NOT_TRUSTED error and the signing command fails with errSecInternalComponent.
**I have confirmed that the certificates are installed in my keychain, but they may be missing private keys or not fully trusted.
Is there a possibility to reset my Apple Developer account’s Developer ID Application and Developer ID Installer certificates, so I can start fresh and generate new valid certificates?
Could you please advise on how to proceed or if there is any way to clear the current certificate limit?**
Thank you very much for your help.

I'm attempting to upload an updated version of our macOS app for distribution via the App Store. We've done this without issue before, but I am now receiving a warning when I upload the app via Transporter:
"Cannot be used with TestFlight because the signature for the bundle at “AXON Studio.app” is missing an application identifier but has an application identifier in the provisioning profile for the bundle. Bundles with application identifiers in the provisioning profile are expected to have the same identifier signed into the bundle in order to be eligible for TestFlight." (90886)
I just recently started seeing this warning when I upload our application via Transporter. Before this warning started happening, I was using the exact same process and scripts to build/package/codesign our application. NOTE: we are not using Xcode to build our application, so we can't take advantage of any codesigning/packaging automation provided by Xcode (the app is written in C#/.NET 6.0), so we are doing all build/package/codesign steps using the appropriate macOS command line utilities. Also, I have verified that the app bundle and its contents have valid signatures.
Does anyone have any idea what may have changed to cause this warning, or how I might go about determining the root cause so I can fix it?
Hello,
We have a working application with several entitlements - com.apple.developer.endpoint-security.client and com.apple.developer.team-identifier.
Recently, the Developer ID signing certificate expired and we created a new one according to the instructions on the website. Also the provisioning profile for those entitlements expired so we edited it to use the new certificate.
We built using xcodebuild in a script and signed with codesign, We supply the certificate id and the entitlement in a plist file like this :
codesign --timestamp --force --sign "${application_signature}" --options=runtime "${obj}" --entitlements "${SR_ENTITLEMENT_PATH}"
(those env vars hold the correct values for the cert id and plist path as far as we checked).
The signing works and looks ok with "codesign -dvvv":
(XXXX replaces the real file name for privacy)
Signature size=9050
Authority=Developer ID Application: XXXXXX. (XXXXX)
Authority=Developer ID Certification Authority
Authority=Apple Root CA

But when the app need to run it is killed and the console shows the following:
amfid: /private/tmp/XXXXX not valid: Error Domain=AppleMobileFileIntegrityError Code=-420 "The signature on the file is invalid" UserInfo={NSURL=file:///private/tmp/XXXXX, NSLocalizedDescription=The signature on the file is invalid} kernel: mac_vnode_check_signature: /private/tmp/CybereasonSensor: code signature validation failed fatally: When validating /private/tmp/XXXXX: Code has restricted entitlements, but the validation of its code signature failed.
We didn't change any code or build differently (it's done by a CI jenkins job.
So if the file is signed and the and has the entitlements why does it fail? what should be done?

I believe that this is related to the post https://developer.apple.com/forums/thread/790880.
I essentially have the same problem that they did. I submit my Distribution PKG for notarization but the notarization fails and when I attempt to install the PKG user the UI I get a "External component packages (3) trustLevel=0 (trust evaluation failed; treating as invalid due to higher trust level for parent product archive)"
However if I install using "sudo installer -verboseR -pkg ConcealDistribution.pkg -target /" everything works as expected.
The difference between me and the other post is that when I expand my PKG using pkgutil --expand I do not have a Resources folder within my top level distribution. Instead my structure looks like
ConcealDistribution
├── Distribution
├── ConcealConnect.pkg
├── ConcealBrowse.pkg
└── ConcealUpdate.pkg
The specific notary service errors I receive are as follows
{
"logFormatVersion": 1,

"message": "The contents of the package at ConcealDistribution.pkg could not be extracted.",

}
]
}
For what its worth all the inner PKGs have their executables signed, the PKGs are signed themselves and they are all notarized and stapled without issue. Then I am attempting to sign and notarize the outer PKG and that is where the problems pop up.
Additionally I'm not sure when this stopped working as I expected but just a few months ago I was able to do this exact same process and install with the UI and have it work.

Hi Team,
I have created multiple certificates for macOS application. Below are the certificates created-
Apple Development Certificate
DeveloperID Installer Certificate
Apple Distribution Certificate
others certificates
Later, I have imported the all these above certificates in keychain-access.
Now, I tried to compile the code through Xcode. I am getting error for code signing certificate.
Warning: unable to build chain to self-signed root for signer "Apple Development: Amit (M2WMF2YERI)”
....
Command CodeSign failed with a nonzero exit code
When I checked the TeamID of User(Amit) I can see that his current TeamID is [P8ZW3W9R2Q].
There is mismatch of teamID in apple development certificate generation.
Note-
All certificates are generated with current TeamID[P8ZW3W9R2Q] of user (Amit) except Apple Development certificate which has been generated with TeamID [M2WMF2YERI] which is generated with old TeamID of user (Amit).
I attempted to generate the apple development certificate multiple times but it is getting generated with old TeamID TeamID[M2WMF2YERI] of user(Amit)
Summary-
While creating a developer certificate using apple developer account and mapping it in keychain, the certificate is being generated with old apple account details (Inactive) instead of the current one. This is causing issues when using the certificate in keychain.
If anyone has encountered this issue, how it was resolved?
Thanks
Hey,
Just recently I realized something I have been overlooking in my build pipelines.
I thought that by adding the the "hardened runtime", I disable 3rd-party library injection (I do not have the disable-library-validation entitlement added).
However, I was using some checks on my code and I noticed that the "library validation" code signature check fails on my applications (e.g. adding the .libraryValidation requirement via the LightweightCodeRequirements framework) - with codesign -dvvvv /path/to/app I can check it doesn't have the CS_REQUIRE_LV flag:
[...]
CodeDirectory v=20500 size=937 flags=0x10000(runtime) hashes=18+7 location=embedded
[...]
then I used in Xcode the "Other Code Signing Flags" setting and added the -o library option, which added the flag:
[...]
CodeDirectory v=20500 size=937 flags=0x12000(library-validation,runtime) hashes=18+7 location=embedded
[...]
Is this flag something I should be explicitly setting? Because I was under the impression enabling hardened runtime would be enough. Popular Developer ID distributed applications (e.g. Google Chrome, Parallels Desktop, Slack) all have this flag set.
