Incremental builds using xcodebuild are very slow, around 3x slower when compared to the same build using Xcode. Recently, I discovered that CODE_SIGNING_ALLOWED=NO" fixed the issue, but of course, I can't then run iOS app. It seems like automatic signing using xcodebuild is somehow broken. Therefore, I think I could set CODE_SIGNING_ALLOWED=NO" and sign it manually later. However, I'm not sure how to do that. I checked what Xcode does and it's: /usr/bin/codesign --force --sign - --entitlements /Users/wkulik/Library/Developer/Xcode/DerivedData/XYZ-hblnhsksxjrctzekqmlevcflnsji/Build/Intermediates.noindex/XYZ.build/Debug-iphonesimulator/XYZ.build/XYZ.app.xcent --timestamp\=none --generate-entitlement-der /Users/wkulik/Library/Developer/Xcode/DerivedData/XYZ-hblnhsksxjrctzekqmlevcflnsji/Build/Products/Debug-iphonesimulator/XYZ.app However, if I run xcodebuild with disabled signing I don't have XYZ.app.xcent required by this command. I also tried: codesign --force --deep --sign "Apple Development: John Snow (XYZ)" /Users/wkulik/Library/Developer/Xcode/DerivedData/XYZ-hblnhsksxjrctzekqmlevcflnsji/Build/Products/Debug-iphonesimulator/XYZ.app but the app immediately terminates (the same way like when unsigned). Could anyone help with that?

Hi Team, mac installer is crashing in macos15 after successfully installing. but it is working in below mac os versions. .app file in successfully code signed and notarized. crash logs is attahced, please check. sh-2024-10-17-124323 2 1.ips below is our entitlement.plist file for reference. we are clueless what is causing issues in macos 15 as we are unable to luanch it post succesful installation. please kind take a look into the logs attached and help us resolve the issues.

Hi all, I have two apple accounts. Stupidly my project is written in Account A and my paid developer account is Account B. When I tried to archive and publish under Account A, it says "Team "*** (Personal Team)" is not enrolled in the Apple Developer Program". But when I add a team to Account B, "Command CodeSign failed with a nonzero exit code". I know it is not the code itself because it runs fine when I use Account A. Just couldn't publish. Any advice? Many many thanks

Codesigned and notarized app cannot directly write files inside the app bundle (neither in my.app/Contents/Resources/ nor my.app/Contents/MacOS/). Are there any restrictions regarding this? Is there a way to bypass these restrictions? Here is the situation I encountered: The main app contains several sub-apps and sub-executables. When the main app calls the sub-apps or sub-executables, it can write files within the app bundle, but when executed directly, it cannot write files. The app is usually opened using the GUI, and when using the command line, neither the main app nor the sub-apps/sub-executables can write files within the app bundle. My codesigning environment is: Sonoma 14.0 on mac mini M1. I manually sign the app directly using the codesign command in CI instead of using Xcode. The process will traverse all of the files and sub-apps in the app folder and sign them from the deepest paths to the shallowest paths. I also tried applying this process to other applications, but all of them encountered the same issue of failing to write files. The app should not be sandboxed (I did not add sandbox entitlements). I have tried adding the entitlement com.apple.security.files.user-selected.read-write, but this has not resolved the issue.

In the past, I used to export a developer-signed test version of my macOS app in Xcode, create a zip archive from the Finder, upload it to my website and share the link to the testers. The last time I did this with macOS 14 the tester was still able to download the test app and run it. But it seems that with macOS 15 the trick to open the context menu on the downloaded app and click Open to bypass the macOS warning that the app couldn't be checked when simply double-clicking it, doesn't work anymore. Now I'm always shown an alert that macOS couldn't check the app for malware, and pushes me to move it to the bin. In this StackOverflow topic from 10 years ago they suggested to use ditto and tar to compress and uncompress the app, but neither worked for me. How can I share macOS apps that I signed myself with testers without physically handing them a drive containing the uncompressed app?

Project Background: I developed a Mac project using Electron and VSCode Successfully uploaded the packaged pkg using Transporter, However, I will receive an email informing me that there are some issues with the project: ITMS-90296: App sandbox not enabled - The following executors must include the 'com. apple. security. app sandbox' entitlement with a Boolean value of true in the entitlement property list: [[com. electron. iflyrecclient. pkg/Payload/iFlytek Listen. app/Contents/MacOS/iFlytek Listen]] ITMS-90886: 'Cannot be used with TestFlight because the signature for the bundle at' iFlytek hears. 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.' Here is my packaging process: Generate an app using the electron packager tool Sign the app using @ electron osx sign (version 1.3.1) After signing, use productbuild - component Yourappname App/Applications - sign "3rd Party Mac Developer Installer: * * * * * (XXXXXXXXXX)" Yourappname. pkg command generates pkg PS： For the second step, I have set sand box=true in both entitlents.plist and entitlents.macinheriting. plist. And after signing, using codesign -dvvv -- entitiements - /path to view the app file shows' checkbox=true ', and the [iFlytek Listen. app/Contents/MacOS/iFlytek Listen] file in the issue also exists. Using the Suspicious Package software to view pkg also has sandbox=true. A few months ago, I uploaded it once and the issues mentioned in the email did not appear. The only changes were the macOS system version number and the replacement of the signature with provisionprofileprovisionprofile. I have reviewed similar issues on the Apple Developer Forums, but have not been resolved

I tried building the React App for Any iOS device (Arm64) but I get error. Although I can build successfully for any iOS Simulators In the codesigning step I get the following error, "Warning: unable to build chain to self-signed root for signer "Apple Development: my email address ( ... ) " I don't have paid membership of Apple Developer Program, does that cause this failure? Also, to archive also do I need Apple Developer Program paid membership?

I work with a team that is responsible for our company's centralized infrastructure for code signing various products within our portfolio, including iOS apps. For security purposes, we want to sign apps before their posting on the App Store, and also to log this activity for eventual security audits. Not surprisingly, we need automated processes; we can't use an IDE like Xcode to do the work. We must queue, process, and log all signing jobs, and have Macs dedicated to this purpose. I can't go into many details about our infrastructure due to confidentiality concerns, so I'll apologize now if my questions seem a little vague. We currently require our iOS developers to submit one or more new provisioning profiles as well as their IPA archive for signing. We support supplying multiple provisioning profiles because some of our developers include embedded third-party extensions within their IPAs, and these extensions can also have their own provisioning profiles. Within our back end, we open the archive, sign the relevant portions using the entitlements in one of the profiles (that we believe to be the appropriate one for the particular archive element), overwrite each supplied provisioning profile with (what we believe to be) the appropriate one from user input, and re-compress the archive. Here come the questions: When we receive multiple provisioning profiles, how do we know which profile should be used to help with signing which archive elements? What data (e.g. entitlements application-identifier, team-identifier) can we use? We also need to know which provisioning profiles from their input correspond to those that already exist within the archive. What data can we use to map profiles from one set to the other? Should we be requiring our users to submit new provisioning profiles in the first place? Or should we edit/recycle the existing ones in some way? We'd like to remove any unnecessary burdens for our users, if possible.

Adobe says that Animate works with the latest Mac OS. When I publish apps with Animate, they work on my computer. With a self-signed certificate, they work on some older Mac OS versions, but not on the 2 most recent. How can I test my apps on others' Mac computers? Robert

I have already posted asking about this: [quote='768005021, CynthiaSun, /thread/768005, /profile/CynthiaSun'] Codesigned and notarized app cannot directly write files inside the app bundle... [/quote] But there are still some doubts that have not been answered. We use Qt to develop an application on the macOS platform, and we are attempting to perform code signing and notarization to ensure our the application is trusted by Apple. However, there are a few things that seem weird regarding this statement: "App bundles are read-only by design." Let me provide more details. Currently, when our application starts, it needs to create folder (e.g. Temp) in the root directory of the executable For example: Myapp.app/Contents/MacOS/Myapp ---> Myapp.app/Contents/MacOS/Temp The folder is designed for storing runtime logs or config files for our application. In the past, users may also modify the settings inside target folder if needed. However, the strange thing is that after the application is codesigned and notarized. When we double-click the application Myapp (a.k.a Myapp.app) in Finder, it could successfully launch and create the Temp folder inside the Myapp.app/Contents/MacOS folder. However, when we navigate and attempt to run the main application executable in command line mode (as our application supports this command line execution) $ cd Myapp.app/Contents/MacOS $ ./Myapp -h As our application will check if the root folder has write permission before starting (i.e., check if Myapp.app/Contents/MacOS is writable because we require to create Temp folder in the following steps) It pop up the error that folder does not have write permission. The aforementioned scenarios seems to conflict with this statement: "App bundles are read-only by design" (because when the application is launched directly by clicking in Finder, the Temp folder can be created successfully, but via the console command line, it cannot). I would like to confirm again if writing files in the notarized application MacOS directory is not allowed? If not, have any recommended approaches? (e.g., changing the folder to another directory). What causes the different results in these running scenarios? We are not concerned about breaking the signature after application launched, as it seems that macOS will add it to system trust list after first time successfully launch. (Download the app from internet --> System: it is an app downloaded from the internet. Are you sure want to open it...? OK --> Although our application creates the Temp folder after first launch, when we click the application second time, it could directly open the app)

Platforms: Ventura and Big Sur Steps to Reproduce: Create new application and installer CSRs with keypairs Generate new certificates in Apple web portal Repackage certificates as .p12 using exported private keys since they are not referenced in keychain app by default. Import certificates into MacOS Keychain Set certificate access to "Always Trust" for all certificate uses Sign binary fails using "codesign --force --sign " Sign installer package succeeds using "productsign --sign Additional Info: The private keys ware initially not recognized by the Keychain application resulting a certificate without a private key "leaf" beneath them. To resolve it I exported the private key and repackaged certificate as a .p12 file. Both certificates appear "good" when evaluated for code signing The installer certificate shows an intermediate and root while the application certificate does not Repackaging as .p12 with expected intermediate and root did not resolve the issue Installing all available intermediates and roots from Apple did not resolve the issue Signing a test app with XCode succeeds In production, we sign using CMake so we need to be able to sign code from the command line with codesign.

I am working on releasing my macOS arm64 app. My problem is that after the user downloads the dmg, double-clicking my.app in the dmg, a Gatekeeper pop-up box will appear with a warning that the developer cannot be verified. Question: Can an application signed with "com.apple.security.cs.disable-library-validation" be published as trusted? If yes, what steps have I missed? If not, can I get an official response from Apple? （Because I referred to this post, it seems to mention that it is possible to publish trusted software.I have looked up similar questions on the forum and tried many things, but nothing works. ） Here are my steps: Use the codesign to sign my.app. Because my app needs to access third-party dynamic libraries, entitlements.plist contains a "com.apple.security.cs.disable-library-validation". After the "codesign -dvvv" check, the signature was successful.✅ Use the "xcrun notarytool" command to notarize my app, and the status is displayed as accepted.✅ Use "xcrun stapler staple" to attach the notarization to my app, and it returns success.✅ Use the "spctl -a -v " command to verify whether my app has passed Gatekeeper, and it returns that it has passed.✅ Then I packaged my.app into a dmg, and then attached the notarization mark to the dmg, which was successful.✅ I completed the above steps and distributed the dmg. When I downloaded the dmg as a user test and double-clicked my.app in it, the Gatekeeper pop-up box still appeared, and the developer cannot be verified.❌

Hello, I'm new at developing an ios app, but I have created a basic app, I plan to use just for me using xcode and the language swift. I intend to use this app, to display a video and images on ipads that will be used as KIOS on a trade show. I don't need this app to be published on the app store as I intend to use it solely for my use. Is there a way I can do something like this that won't be restricted with the 10 days restriction? I learned xcode/swift as little as I could to create the app, but now I'm limited to the 10 days, and only 3 devices. Is there a way I can create an offline app, that doesn't have the all the restrictions? I plan to use these ipads over and over again on tradeshows to display my work.

Hi, I am a long time programmer in C#, and newer to Rust, and a rookie to MacOS 15.1. Over the past few days I have made numerous attempts to run a Rust GUI binary that I compiled on Mac. Here are some examples of things I have tried using. Executable compiled in M1 mac not running on Apple Silicon Mac - help - The Rust Programming Language Forum And here.... How to run unsigned apps in macOS 15.1 Also here... "sudo spctl --master-disable" There are many more that I have tried. I also tried moving the binary from my developer folder to the Application folder and running.... xattr -r -d com.apple.quarantine /Applications/csv Note that "csv" is the name of my binary. You have probably seen this 100 times, so can you point me to me to something that allows my Rust binaries to run under MacOS? PS The Rust program code works just fine under Linux. I can either type Cargo Run and run the binary from the Terminal or go directly to the executable and double click on it to open the GUI application. The only thing that MacOS lets me do it open the GUI from the Terminal. Commander One says that I do not have the proper credentials to open the file directly. Finder also does not allow me to open the binary directly. Thanks, Jim

Hi, I know my swiftui, but I'm completely new to macOS development. Using Xcode 16.2 I wrote a backup app that fits my needs. I got it to use iCloud Documents in its own container. It runs beautifully on my developing Mac. When I copy it over to my other Mac and try to open it, I just get a message that macOS can't open the app ("Das Programm kann nicht geöffnet werden") In terminal I get this message: "embedded provisioning profile not valid: file:///Users/niko/FlexBackup.app/Contents/embedded.provisionprofile error: Error Domain=CPProfileManager Code=-212 "Provisioning profile does not allow this device." I have "automatically manage signing" turned on and a Xcode Managed Profile. How can I run my app on all of y Macs?

Hi, For the purposes of iteration speed in development builds, on an iPhone in development mode, I am attempting to use hot reloaded dylibs. The goal is that the app is rarely fully restarted and small code changes can be applied quickly, drastically reducing iteration speed. For this purpose I have a socket server on my Mac that sends changed dylibs to my app on my iPhone. This works great on Mac, however on iOS i am running into codesigning problems. I am using the following to codesign the dylib: codesign -f -s *** --timestamp=none testlibrary-ios.dylib I am placing the downloaded dylib in this folder: const char* cachedirectoryPath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)[0] UTF8String]; dlopen gives me the following error: dlopen(/var/mobile/Containers/Data/Application/67A3D31B-6F72-4939-9E7F-665FC78CDC61/Library/Caches/testlibrary-ios.dylib, 0x000A): tried: '/usr/lib/system/introspection/testlibrary-ios.dylib' (no such file, not in dyld cache), '/var/mobile/Containers/Data/Application/67A3D31B-6F72-4939-9E7F-665FC78CDC61/Library/Caches/testlibrary-ios.dylib' (code signature invalid in <78A101AD-D756-3526-8754-8B7F4925DE90> '/private/var/mobile/Containers/Data/Application/67A3D31B-6F72-4939-9E7F-665FC78CDC61/Library/Caches/testlibrary-ios.dylib' (errno=1) sliceOffset=0x00000000, codeBlobOffset=0x0000C2E0, codeBlobSize=0x00004990), .... Is loading a dylib like this on iPhones in development mode possible? Any idea what is going wrong with codesigning or installing the dylib? (Obviously this code is never deployed in an app that goes on the AppStore)
