unzip identifier is not unique?
In Swift I'm using unzip by launching a Process to unzip a file. I added a launchRequirement to the process in order to make sure the executable is code signed by Apple and the identifier is com.apple.unzip. After testing out my code on another machines (both physical and virtual), I found out that in some the identifier is actually com.apple.zipinfo, which broke the SigningIdentifier requirement. It's safe to assume that /usr/bin/unzip can be trusted since it's in a System Integrity Protection (SIP) location, but I'm wondering why this executable has different identifiers?

Codesign can't find keychain files (on M2 MacBook)
I've been distributing my Math Education app (Java-based) as a downloadable .dmg. My sw manufacturing process was working well on my Intel-iMac a year ago (signing, notarization, stapling). I need to support Apple Silicon, so I replicated the SW manuf. stack on my M2 MacBook, including putting my Developer and Installer Certificates in the Keychain Access. I get through building the M2,M2,M4 .dmg installer file just fine. But the Codesign is failing. It should be prompting me for my MacOS password (it does this in the Intel-Mac process), but fails this command: codesign --sign "Pierre Bierre (SL7L4YU8GT)" --force --options runtime --verbose --timestamp ~/DFG2D_MacOS_Manufacturing/MacOSInstallers/DFG2D_Mac_J17010_295 The response was: error: The specified item could not be found in the keychain. The signer reference is correct, and works fine on the Intel-Mac codesign process. What could explain why the same script fails in the M2 environment? Does codesign normally prompt for the MacOS user password ? Why would that fail?

Mac App Packaging
Can someone please explain why Mac app packaging is so farcically convoluted? Windows app packaging can be picked up in an hour or so. But I've spent longer trying to fathom how to package the Mac version than I did building the app. And it's not done with me yet. Every single line of code requires a deep dive into a new, unrelated skillset. So, it’s sidebar after sidebar. Kafka’s ‘The Trial’ comes to mind. Why does it have to be like this?

After years, notarytool now cannot find Keychain item
For years, I've been shipping my apps with a Perl script that now invokes notarytool to get the notarization, using this command /usr/bin/xcrun notarytool submit --apple-id jerry@sheepsystems.com --keychain-profile SSYShipProduct --team-id 4MAMECY9VS --output-format json /Users/jk/blah/blah/MyApp.zip --wait I used this script with this command several times during September 2024 to ship my apps, and it worked. But now, the above command fails with: Error: No Keychain password item found for profile: SSYShipProduct Run 'notarytool store-credentials' to create another credential profile. Of course, I am now running later versions of macOS beta and Xcode than I was in September. Does anyone know the problem? Screenshots from Terminal and Keychain Access are attached. Thank you.

Failed qualification checks ad-hoc profile
Hi, We have an app that is a default mail client, so it has this entry in its entitlements file: com.apple.developer.mail-client. This seems to create issues with ad-hoc distribution. We can distribute the app on App Store Connect without any issues and have been doing so for a while. We wanted to try using Xcode Cloud to manage our releases. The app export works fine for both App Store Distribution and Development Distribution. However, the ad-hoc distribution step fails. (We don't need ad-hoc distribution, but Xcode Cloud seems to prevent us from removing this step.) I tried building and releasing the app locally for ad-hoc distribution and encountered the same error as on Xcode Cloud. When Xcode tries to generate the profile, it outputs the following error: Provisioning profile "iOS Team Ad Hoc Provisioning Profile: com.infomaniak.mail" failed qualification checks: Profile doesn't support Default Mail App. Profile doesn't include the com.apple.developer.mail-client entitlement. Is it something broken with our config ? What are we missing ? Local error in Xcode Organizer: Remote error on Xcode cloud:

Test my app without ADP membership
Hello community, I'm new here, so please excuse my blunt question. I'm trying to understand how everything works and the logic behind it. I have an idea for an app which requires the FamilyControl entitlement. Now I am not sure if the idea even works, so I wanted to test it on my own device. Am I correct, that I cannot even test an App with such entitlements without paying for the ADP? Not even on my own device? I completely understand I need to be a member in the ADP if I want to distribute my app, but I'm not there, yet, and I just want to do a proof-of-concept. I thought I can't be the first one with that question, but couldn't find a past topic on this, so I'm posting it. Regards, Niklas

App Store code signing show "Beta Profile"
I encountered code signing issue with Apple Distribution certificate for both iOS and MacCatalyst. The app crashes with "Beta Profile". I followed this instruction to manually re-sign my ipa to confirm that I use the Apple Distribution and the correct Provisioning Profile. https://gist.github.com/WDUK/4239548f76bd77b2c4b0 When I double click on the Apple Distribution certificate in KeyChain Access, it shows "Extension: Apple Mac App Signing (Development)" and "Extension: Apple Developer Certificate (Submission)" I have been stuck in this issue for more than a month. I really need help because I do not know how to proceed further. Thank you.

Xcode failed to provision target. File a bug report...
I do have background Modes added to Xcode. How can I fix this? Automatic signing failed Xcode failed to provision this target. Please file a bug report at https://feedbackassistant.apple.com and include the Update Signing report from the Report navigator. Provisioning profile "iOS Team Provisioning Profile: com.designoverhaul.bladerunner" doesn't include the com.apple.developer.background-modes entitlement. I emailed Dev Support but they said they cant help. Thank you.

Invalid Code Signing Entitlements
Hi, I have a .NET MAUI app which I've added subscriptions to using the Plugin.InAppBilling nuget package. When I tested on TestFlight I got an almost immediate crash. After doing some research I followed advice to add an Entitlements.plist file to Platforms > iOS with the following entry: com.apple.developer.in-app-purchase The distribution provisioning profile I'm using to sign my app has the App ID set to an Identifier which has "In-App Purchase" ticked, but greyed out in it's "Capabilities" section on https://developer.apple.com/. I'm not sure why it's ticked and greyed out, but I assume that means that "In-App Purchase" is enabled. The app runs file locally but when I create an IPA file and add it to Transporter for upload to App Store Connect I get the following error: "Validation failed (409) Invalid Code Signing Entitlements. Your application bundle's signature contains code signing entitlements that are not supported on iOS. Specifically, key 'com.apple.developer.in-app-purchase' in 'Payload/[Removed].app/[Removed]' is not supported. (ID: [Removed])". Here is the structure of my csproj code for creating a IPA file for iOS: The command I use: dotnet publish [Removed]/app.csproj -f:net9.0-ios -c:Release ^ /p:PlatformTarget=Arm64 ^ /p:RuntimeIdentifier=ios-arm64 ^ /p:ServerAddress=[Removed] ^ /p:ServerUser=[Removed] ^ /p:ServerPassword=[Removed] ^ /p:ArchiveOnBuild=true ^ /p:BuildIpa=true I'm stuck trying to figure this out. If you could please point out any issues with what I'm doing or if you have any suggestions to resolve the problem I would very much appreciate it. Thanks, Ben

how to handle setup for NFC without NDEF & PACE and still support iOS 15.0
We have NFC capabilties enabled for our app ID - com.uob.mightyvn but our minimum deployment target is 15.0. We do not have an option deselect PACE from provisioning profile. Hence, the validation is failed for IPA. Invalid entitlement for core nfc framework. The sdk version '18.2' and min OS version '15.0' are not compatible for the entitlement 'com.apple.developer.nfc.readersession.formats' because 'NDEF is disallowed'

Can't run app on iPhone after registered UDID
The device UDID was registered to the developer account 40 hours ago, the STATUS column was "processing" in the first 24 hours, then turned to empty. But I still can't run my app (with distribution method "development"), when I try to run it after download it through my OTA URL, it prompts “the app cannot be installed because its integrity could not be verified” but everything runs good on a iPhone which was registered a month ago. What should I do now? keep waiting?

Error 65 upon stapling - cannot reset trust settings
Hi, I'm getting error 65 upon stapling and I am suspecting that non-default trust settings may be the reason as outlined here: Unfortunately whatever I do, I can't seem to reset the trust settings to their default values (removing the blue/white "+"), I'm not being asked for credentials upon closing the certificate window. I have also tried to unlock the System Roots key chain, to no avail. Also, when running security dump-trust-settings -d I get Number of trust settings : 0 for all certificates. Any ideas as to what I may be doing wrong? Is there any other setting that may be involved? Thanks!

Migrating Identifier from non-team prefix within single account
Hello, In our Account we have an iOS app with an explicit identifier "ABC123.com.some.app" that is using non-team prefix which is DEF456. It has also explicit identifiers for Widgets bundle and Notification Service. Due to non-team prefix, it can't access e.g. shared keychain and data put there by our other apps. Since we are working on features that require these capabilities, we would like to update the app identifier, so it is prefixed with our team id DEF456. Initially, we thought that the process would require steps like: Create new app, team-prefixed identifier(s) for app and all things that need them Recreate the provisioning profiles with new App Identifier Roll out the app using with new profiles via App Store but when trying to create the new identifier with com.some.app and team id prefix DEF456 we are getting following error: An App ID with Identifier com.some.app is not available. Please enter a different string. Can anybody advise us how to correctly perform such change and what steps are required from our end? We would like to keep our existing App Store entry, ratings and smoothly switch users. We are aware that this kind of migration results in loss of Keychain access. Thanks for any advice on that!

FamilyControls App Blocking Not Working for External TestFlight Testers
Hi everyone, I'm following up on this post I made earlier about an issue I'm having with FamilyControls and the DeviceActivityMonitor extension not working for external TestFlight testers. To briefly recap: I have official Apple approval for the com.apple.developer.family-controls entitlement (distribution) The entitlement is added to both my main app and the DeviceActivityMonitor extension The App Group is correctly configured for both targets On internal TestFlight builds, everything works as expected: app blocking works, the extension runs, and selected apps are shielded. On external TestFlight builds, users get the Screen Time permission prompt, can select apps to block, but nothing is blocked. Since that post, I submitted a Code Level Support request, and Apple asked me to file a bug report via Feedback Assistant. I did that almost a month ago. The only reply I’ve received since is that they can’t give a timeframe or guarantee it will be resolved. I'm stuck in limbo with no updates and no fix. This feature is critical to my app and I cannot launch without it. I’ve reached out to other developers who use app blocking, and none of them have run into this issue. My setup seems correct, and Apple has not said otherwise. If anyone has experienced something similar, found a workaround, or knows how to get real movement on a bug report like this, I would really appreciate any help. It’s been weeks, and I just want to launch my app. Thanks so much.

Provisioning Profile Defect: App Attest Entitlement (com.apple.developer.app-attest.environment) Missing Despite Enabled Capability
Hello everyone, I'm facing a critical, blocking issue where my developer account (Team ID: K655PX7A46) is unable to generate a valid provisioning profile with the App Attest entitlement. I have confirmed this is a server-side issue and am hoping to get visibility from an Apple engineer who can investigate. The Problem: When I generate a provisioning profile for an App ID with the "App Attest" capability enabled, the resulting profile is defective. It is missing the required com.apple.developer.app-attest.environment key in its entitlements dictionary, causing Xcode to fail the build. What I Have Proven: The issue is not a misconfiguration. The App Attest capability is correctly enabled and saved on the App ID configuration page. The issue is not isolated to one App ID. I created a brand new App ID from scratch, enabled the capability during creation, and the server still generates a defective profile with the same missing entitlement. I have definitive proof by inspecting the downloaded .mobileprovision file. The contents confirm the required key is missing. Steps to Reproduce on My Account: Create a new App ID on the Developer Portal. Enable the "App Attest" capability and save. Generate a new "iOS App Development" provisioning profile for this App ID. Download the profile and inspect its contents via security cms -D -i [profile]. Observe that the com.apple.developer.app-attest.environment key is missing. The Evidence (Contents of the Defective Profile): Here is the output from inspecting the profile for a brand new App ID (com.technology519.linksi.app2). As you can see, the correct entitlement is missing, and an incorrect devicecheck entitlement is present instead. This is a critical bug in the provisioning profile generation service for my account that is blocking all development. I have already filed a support ticket (Case #102721408444) but have so far only received generic, unhelpful responses. Can an Apple engineer please investigate this server-side issue with my account? Thank you.

Resolving Tap to Pay on iPhone errors when building for App Store or TestFlight distribution
I am receiving an entitlement error from stripe terminal SDK when integrating Tap to Pay from apple in the info.plist. Im hoping that someone can give me their input on my error output rather than diving into the stripe sdk to point me in the right direction of something I may have missed with entitlements. I have been approved for tap to pay entitlement and am following the instructions here from apple: https://developer.apple.com/documentation/proximityreader/setting-up-the-entitlement-for-tap-to-pay-on-iphone com.apple.developer.proximity-reader.tap-to-pay

No profiles for 'xxx.xxx.xxx.xxx' were found
We've been creating iOS apps for a few years now, but when I tried last month, I got an error in my XCode that says: No profiles for 'com.os.hub.mth2' were found Xcode couldn't find any iOS App Development provisioning profiles matching 'xxx.xxx.xxx.xxx'. I'm not sure if it's the cause or not, but when I look at the signing certificates, the Developer ID Application Certificate says: Missing Private Key The weird part of that is that I see a private key with this name in my Keychain access, so I'm not sure what's wrong. There has been a significant time gap between now and the last time we created a mobile app, so I'm not sure if something changed in XCode/MacOS to cause this issue, or if something expired. I'd appreciate any advice.
