NSTask launchRequirementData
I've noticed that NSTaks has this property as of macOS 14.4 @property (nullable, copy) NSData *launchRequirementData API_AVAILABLE(macos(14.4)) API_UNAVAILABLE(ios, watchos, tvos, visionos); It has no documentation whatsoever. Even google search has no clue. Does this have anything to do with code signature requirements validation? Any explanations and examples would be appreciated!

Developer ID Certificate (How to replace damaged certificate?)
How do I replace an Apple Developer ID Certificate that indicates it is not trusted? When I look at my Certificate Expiring 02-20-2025, I see a valid status displayed. (See annotation #1.) However, when I look at my Apple Developer ID Certificate renewal, I see the words not trusted. (See annotation #2.) I downloaded the renewal certificate and double double-clicked the downloaded item to place it in my KeyChain. This certificate period is from 01-21-2025 to 01-22-2030. QUESTIONS Why does the renewal certificate say "certificate is not trusted"? (Its period is 01-21-2025 to 01-22-2030. Today is 01-27-2025.) How did the renewal certificate get damaged? What must I do to get the damaged certificate replaced with a valid one?

Codesigning completes, Notarization fails using notary tool
Notarization step fails: New AppID and password created: xcrun notarytool submit “.dmg” --apple-id “” --team-id “” --password “” --verbose --wait Error: HTTP status code: 401. Your Apple ID has been locked. Visit iForgot to reset your account (https://iforgot.apple.com), then generate a new app-specific password. Ensure that all authentication arguments are correct. I have reset app password many times, not result. Codesigning completes normally: Mac OS 11.5.2 Xcode 13.2.1

How does xpc_connection_set_peer_code_signing_requirement work?
I have created a XPC server and client using C APIs. I want to ensure that I trust the client, so I want to have a codesigning requirement on the server side, something like - xpc_connection_set_peer_code_signing_requirement(listener, "anchor apple generic and certificate leaf[subject.OU] = \"1234567\"") This checks if the client code was signed by a code-signing-identity issued by Apple and that the teamID in the leaf certificate is 1234567. My questions are- Is using teamID as a signing requirement enough? What else can I add to this requirement to make it more secure? How does xpc_connection_set_peer_code_signing_requirement work internally? Does it do any cryptographic operations to verify the clients signature or does it simply do string matching on the teamID? Is there a way actually verify the clients signature(cryptographically) before establishing a connection with the server? (so we know the client is who he claims to be)

What is the right procedure for asking for entitlements ?
I want to use the com.apple.vm.networking entitlement which has a note: This entitlement is restricted to developers of virtualization software. To request this entitlement, contact your Apple representative. https://developer.apple.com/support/technical/ says: « Request entitlements using entitlement forms and ask for status updates in the resulting email thread. » but I haven't been able to find these "entitlement forms". Does anyone know what the right process is to request an entitlement?

Notarize with Enterprise API Key
Hello! I've been facing an issue with notarizing a macOS app with an Enterprise API Key. Due to some misunderstanding setting up the project some years ago, the notarization step was using a developer's accounts API Key. I am looking to fix it to have everything centralized in the Enterprise account we work with, but I get "Debug [JWT] Generating new JWT for key ID" with the new key. This is using the xcrun notarytool directly to get more input. Using Fastlane it fails as: Error polling for notarization info: [11:29:25]: unexpected token at '' The project is deployed via MDM, so we need it to prevent the security warning. I used this documentation to create the key: https://developer.apple.com/documentation/enterpriseprogramapi/creating-api-keys-for-enterprise-program-api I have tried a Developer and an Admin access key, and the Account Holder has also created an Admin key but the errors keep the same. I just updated my Fastlane script to use the new key with the updated values. The old developer account key still works. I am not sure if I am missing any steps in the documentation or if this is not achievable. Important to add that all the profiles and certificates were already set up properly in the Enterprise account, the only error was using an App Store Connect Key instead of an Enterprise Key. Thanks in advance for the help.

iPad contoroled by MDM Profile can't connect Wi-Fi
iPad(第10世代、iOS v18.1)でMDMを使用してWi-Fiを設定すると、「ネットワーク「SSID名」に接続できない」という問題が発生しています。 この件についてアドバイスをいただければ幸いです。 私が取った手順は次のとおりです。 1.iPadをWi-Fiに接続し、Wi-Fi情報(SSID、ユーザー名、パスワード)をカスタム属性値としてMDMに登録します。 2. MDMから、Wi-Fiプロファイルをデバイスに配布します。 3.Wi-Fiプロファイルがデバイスにインストールされ、その後、ネットワークは自動的に切断されます。 ネットワークに再接続 4.To、OS設定の「Wi-Fi > My Network」に表示されているSSIDをタップしてください。 5.次の証明書画面で、「信頼」ボタンをタップします。 ここで、「ネットワーク「SSID名」に接続できません」というエラーが発生しました。 Appleサポートの提案に基づいて、以下を確認しました。しかし、問題はありません。 1.ルーターの電源がオンになっており、デバイスが通信範囲内にあります。 他のデバイスはWi-Fiに接続できるので問題ありません。 2.Wi-Fiがオンになり、ネットワークが認識されていることを確認します。 Wi-Fiが「オン」で、ネットワークが認識されます。 3.入力画面が表示された場合は、Wi-Fiパスワードを入力します。 入力画面が表示されません。 4.Wi-Fiネットワークに問題がないことを確認します。 接続されているWi-Fiネットワークの名前の下にWi-Fi警告/エラーは表示されません。 5.ケーブルと接続状態を確認します。 他のデバイスはWi-Fiに接続できるので問題ありません。 6.iPadを再起動します。 iPadを再起動しました。しかし、問題は解決しませんでした。 OS:iPadOS18.1 デバイス:iPad第10世代

Mac catalyst stuck at notarize
I have created a Mac Catalyst version of the same app, and it was transferred from an old account to a new one. However, the Mac Catalyst build has been stuck in progress for several days when attempting to notarize it. After many days, I got the rejection with the following error: Team is not yet configured for notarization. Please contact Developer Programs Support at developer.apple.com under the topic Development and Technical / Other Development or Technical Questions. I have already tried to create a new developer ID certificate, but it still has the same issue. On the other hand, the iOS app is working fine and has been published in the App Store. Could you please assist us in resolving this issue as quickly as possible? Your prompt help would be greatly appreciated.

The binary file is getting quarantined (com.apple.quarantine) while downloading onto another system even though it's digitally signed by a developer ID and notarised.
We are using SHC to compile on macOS to convert the .sh script to a binary file. This binary file is then digitally signed by the Apple developer account and then notarised. After that, it will work on the same system where we follow this process. But if we share this file to another system, then it gets quarantined (com.apple.quarantine) while downloading. Is there any way to prevent it by getting quarantine on another system or something I'm missing, any clues?

Urgent: xcrun notary submit Stuck - Notarization Process Halted
Hi everyone, Native Instruments is encountering a critical issue with the notarization process. The xcrun notary submit command appears to be stuck and is not completing, preventing us from notarizing our apps. Specifically, the command hangs indefinitely. This issue started today. We've already tried the following troubleshooting steps: Cancelling and re-running the command Checking my internet connection Checking the Apple System Status page Cleaning the build folder using a different machine This is a major blocker for our company, as it's preventing from from us from testing and releasing some of our products. It seems to be a similar issue as reported in https://developer.apple.com/forums/thread/772542?page=2. Has anyone else experienced xcrun notary submit getting stuck like this? Any insights or suggestions would be greatly appreciated. I'm particularly interested in knowing if there are any known issues with the notarization service currently. Details about my setup: Xcode Version: 16.1 macOS Version: 14.7.1 App Type: macOS app Thanks in advance for your help!

Unable to install Audio App Extension on iOS Device
I keep getting this error when trying to install Audio app extension. Everything is reviewed from certificates to profiles, for some reason CreatingCustomAudioEffects sample is deployed correctly but when Creating new Project (Audio Extension App) from new project Option, it doesn't work at all. If I remove Extension from Frameworks and deploy app, then no problem but then App crashes as extension is missing. Something wrong with Xcode? I am pretty sure it used to build new projects but not anymore. Failed to verify code signature of /var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.0k1RXy/extracted/AudioUnitsAppExtensionTest.app : 0xe8008015 (A valid provisioning profile for this executable was not found.) Please ensure sure that your app is signed by a valid provisioning profile. If this issue persists, please attach the following when sending a report to Apple: A sysdiagnose from this Mac A sysdiagnose from the device failing installation An IPA of the app failing installation

Unable to sign .app file with Developer ID installer certificate
I am using matlab to create an application (.app) using matlab application compiler. Along with that, I use matlab to create an installer for that. Unfortunately, the installer is in (.app) format. So do some custom things to install the dependencies and copying my application to Applications folder. I am able to sign the original application with Developer ID application certificate. But I am not able to sign the installer in .app format with Developer ID installer certificate. Is there any flag in any signing executable that allows me to use Developer ID installer certificate to sign .app file instead of typical (.pkg/.dmg)? Any help would be much appreciated.

Cosign issue
I am a new macOS developer, and the codesign issue is persistent. I've been trying to resolve it for days. There are two issues: 1.) When downloading and installing frameworks, they are not showing up in Xcode templates. 2.) Regarding codesigning, even though I've installed it on my external drive and placed it in various locations (Library, Templates, Frameworks, Application Contents, macOS Templates and Frameworks) and added through General Libraries in Xcode, persistently encountering issues. I'm experiencing a codesign problem. I've cleaned the build, cleared derived data, downloaded certificates, added them to the access key, and linked the binary. However, the issue persists. Please help me, as this is making the process much more difficult. I've been stuck on this for weeks.

Notarised app crashing, build app not crashing
I have an app that only crashes once it's been notarised. I read a few posts that essentially said before trying to identify issues by reviewing the crash report I should ensure signing and notarisation has happened correctly. I've worked through the document "Resolving common notarization issues" spctl -vvv --assess --type exec: gives no errors and correctly returns my developer id. codesign -dvv: returns a timestamp My app uses a hardened runtime. My app shows up in Xcode as a macOS Archive (e.g not a Generic Xcode Archive) Here is the crash report. Translated Report (Full Report Below) Process: Scene Finder [44479] Path: /Users/USER/Downloads/Scene Finder.app/Contents/MacOS/Scene Finder Identifier: Version: 0.9 (20250206.1) Code Type: ARM-64 (Native) Parent Process: launchd [1] User ID: 501 Date/Time: 2025-02-11 13:09:03.7786 +1000 OS Version: macOS 15.3 (24D60) Report Version: 12 Anonymous UUID: EE8B1269-0A8A-3AB6-516B-C752E8A18B5A Sleep/Wake UUID: 436CD7CF-7B13-4A9C-9425-7EF94CC007A9 Time Awake Since Boot: 98000 seconds Time Since Wake: 9524 seconds System Integrity Protection: enabled Crashed Thread: 0 Dispatch queue: com.apple.main-thread Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Termination Reason: Namespace SIGNAL, Code 6 Abort trap: 6 Terminating Process: Scene Finder [44479]

Export archive for app-store distribution command: 'xcodebuild -exportArchive -archivePath ...' exited with non-zero exit-code: 70
Hi, I have a project that integrates the Firebase SDK via SPM as a dependency of an internal Swift Package: My app ⟶ My Library ⟶ Firebase SDK The project builds successfully and can be archived locally ✅. The uploaded .ipa is valid and gets published 🚀. However, we are now trying to automate the release process using Xcode Cloud, but the iOS Archive action is failing ❌ on Xcode Cloud. The logs show the following error ⬇️: error: exportArchive codesign command failed (/Volumes/workspace/tmp/XcodeDistPipeline/XcodeDistPipeline.~~~oomCvM/Root/Payload/base-ios.app/Frameworks/FirebaseAnalytics.framework: replacing existing signature /Volumes/workspace/tmp/XcodeDistPipeline/XcodeDistPipeline.~~~oomCvM/Root/Payload/base-ios.app/Frameworks/FirebaseAnalytics.framework: invalid or corrupted code requirement(s) Requirement syntax error(s): line 1:178: unexpected token: <COMPANY_NAME> ) ** EXPORT FAILED ** I have been researching this issue for a while and have tried several solutions to fix it, but with no luck. Even though the error points to a specific library—the Firebase SDK—I don’t believe Firebase is the root cause. There were related issues in the past, but those were already fixed by the Firebase team, and as I mentioned, the project archives correctly when built locally. On the other hand, the error states: line 1:178: unexpected token: <COMPANY_ACRONYM> This makes me wonder if there’s an issue parsing our Team Name during the re-signing process, as it contains special characters ": "name": "Apple Distribution: Company Full Name "COMPANY_ACRONYM""

Best Practices for Maintaining Long-Term Validity of Signed XCFrameworks
I am developing and distributing an XCFramework, and I want to ensure that it remains valid for as long as possible. I have some questions regarding certificate expiration and revocation: I understand that if an XCFramework is signed with a timestamp, it remains valid even after the signing certificate expires. However, if the signing certificate is revoked, the XCFramework immediately becomes unusable. As far as I know, Apple allows a maximum of two active distribution certificates at the same time. I assume that once a certificate expires, it will eventually need to be revoked in order to issue a third certificate. Is this correct? If an expired certificate is later revoked, will the XCFrameworks signed with that certificate also become invalid, even though they were timestamped? I want to ensure that released XCFrameworks remain valid for as long as possible. What is the best approach to achieve this? If anyone has insights or official documentation references on how to manage signing certificates for long-term XCFramework validity, I would appreciate your guidance. Thank you!
