Overview

We have encountered a problem where the dyld ends up using the incorrect dylib. Here's the use case: Plugin A (a bundle) depends on Dynamic Library A - referenced with "@loader_path". Plugin B (a bundle) depends on Dynamic Library B - referenced with "@loader_path". Relevant File (binaries) layout is like this: MyPluginA.bundle/Contents/MacOS/MyPluginA [depends on @loader_path/../../../MyLibraryA.framework/MyLibrary] MyLibraryA.framework/MyLibrary MyPluginB.bundle/Contents/MacOS/MyPluginB [depends on @loader_path/../../../MyLibraryB.framework/MyLibrary] MyLibraryB.framework/MyLibrary This scheme works fine on most machines. But on some Macs, dyld tries to link MyPluginB with the library in MyLibraryA - which causes the plugin not to be loaded because it cannot find the required symbols in the library. If we try to print dyld debug information, it shows that MyLibraryB is loaded and then unloaded, without showing any reason. And following that, the MyPluginB tries to look for MyLibraryB's symbols in MyLibraryA. Can this be due to some kind of caching done by dyld? Why is the @loader_path not being used to refer to the actual library being used?

Hi. My MacOS application (Obj-C, Cocoa MacOS 10.15 or later) sets itself as delegate for UNNotificationCenter, and implements both - (void)userNotificationCenter:(UNUserNotificationCenter *)center        willPresentNotification:(UNNotification *)notification          withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler and - (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(nonnull UNNotificationResponse *)response          withCompletionHandler:(nonnull void (^)(void))completionHandler It creates and schedules many user-notifications (mostly with no "trigger" meaning - present to the user ASAP and sometimes 2.5 seconds in the future, so to group notifications better. Each notification is also holding som dictionary of "UserInfo" containing some data. My AppDelegates handles user responses (both standard open, cancellation, and "cancel-all") and also custom user-actions I attach to the category. All works well on most Macs and almost always. However - On few Macs, at arbitrary times, users complain that "clicking a notification in Notification Center will not open the app" and that "expected notifications are missing altogether". My logs show the following. Quite frequently I see the following: error log lines: 2023-02-16 17:32:21.413065+0200 0xa58109d Error 0x0 51690 0 <UserNotifications`__104-[UNUserNotificationServiceConnection addNotificationRequest:forBundleIdentifier:withCompletionHandler:]_block_invoke_2.cold.1> myApp: (UserNotifications) [com.apple.UserNotifications:Connections] [com.myCompany.myApp] Adding notification request failed with error: Error Domain=NSCocoaErrorDomain Code=4097 "connection to service on pid 451 named com.apple.usernotifications.usernotificationservice" UserInfo={NSDebugDescription=connection to service on pid 451 named com.apple.usernotifications.usernotificationservice} followed by my own log lines - like this: 2023-02-16 17:32:21.413279+0200 0xa5811b5 Error 0x0 51690 10 <myApp> myApp: [com.myCompany.myApp:UI] NotificationRequest B6096CDE-6229-42AA-A6BC-EBCC06540C53 stage:scanFinished failed to schedule: Error Domain=NSCocoaErrorDomain Code=4097 "connection to service on pid 451 named com.apple.usernotifications.usernotificationservice" UserInfo={NSDebugDescription=connection to service on pid 451 named com.apple.usernotifications.usernotificationservice} Of course - the un-scheduled notification won't appear to the user, but worse - clicks on other, DELIVERED notifications, won't call back my delegate. Strangely enough - few seconds later, sometimes minutes - other attempts to schedule new notifications - succeed without any error. I guess this "connection" is somehow automatically re-established. I looked for information about this error (Domain=NSCocoaErrorDomain Code=4097) and it seems to be pretty generic, and used for many scenarios where connection to some service is lost. Of course my code doesn't maintain any such connection manually/programmatically - I guess it is the [UNUserNotificationCenter currentNotificationCenter] implementation which holds connection to its "daemon" or "agent" or some XPC service. The really bad thing here - is that I DO NOT KNOW how to improve anything here. [UNUserNotificationCenter currentNotificationCenter] Is a singleton, that I can't control, or re-create, to somehow revive the connection There is no way I know of, to tell it to do so, or even to check whether it has a connection. I rely on Notification-Center to maintain my MODEL DATA for scheduled requests, in case my App is relaunched - and now I can't get it. Please advise. this is quite urgent for me. The issue appears more on Big Sur.

We are facing a issue, when the app goes to background and we try to get back to foreground, the app crashes.

I wrote an app that successfully adds a cycling workout to HealthKit. I can see in the Health app that there are new entries under "Workouts", "Active Energy", and "Exercise Minutes" all from me just adding an HKWorkout and a HKQuantitySample. However, there is no new entry for "Cycling Distance". I assumed that since the workout I added includes the fact that the activityType is HKWorkoutActivityType.cycling and I provided the distance, that it would also add an entry for "Cycling Distance". Is there something extra I need to do to get that?

Exporting pdf from Safari is the best export tool by far, comparing all the existing ones of other browsers. Great job, Apple!! It is very useful for rendering web pages to pdf for signing documents for legal purposes. But here is the problem: Safari cannot generate page breaks in din A4 format. The pdf resulting from the export is two or three pages with different rare page sizes. If it were possible to preset the page size would be perfect. That way, it could also be printed if needed. Thank you in advance for your help. Pablo

Is it a feature of Developer Mode that apps constantly relaunch? I wonder if it’s this, or some other reason. My phone is not the newest but I don’t see this behaviour with DM off. It makes it difficult to gauge how often my app actually need to relaunch, when it’s relaunching every time. Xcode 13.4.1, iOS 16.3.1

I desperately need a reliable tutorial on creating and implementing a Privileged Helper for this app I'm creating. I have found a couple of resources on the web, but they are not well-written and dated. Can anyone help point me in the right direction? Documentation seems to be very sparse.

I am trying to modify an existing bundle so that I can notarize it. Here its organisation: graps.app Contents MacOS prelaunch <-- main applauncher grasp <-- auxiliary binary calling the libraries Here the original DYLD_LIBRARY_PATH: DYLD_LIBRARY_PATH="." DYLD_LIBRARY_PATH="$DYLD_LIBRARY_PATH:/Applications/MATLAB/MATLAB_Runtime/v911/runtime/maci64" DYLD_LIBRARY_PATH="$DYLD_LIBRARY_PATH:/Applications/MATLAB/MATLAB_Runtime/v911/bin/maci64" DYLD_LIBRARY_PATH="$DYLD_LIBRARY_PATH:/Applications/MATLAB/MATLAB_Runtime/v911/sys/os/maci64" export DYLD_LIBRARY_PATH and the RPATHs that mimic it: install_name_tool -add_rpath "/." grasp install_name_tool -add_rpath "/Applications/MATLAB/MATLAB_Runtime/v911/bin/maci64" grasp install_name_tool -add_rpath "/Applications/MATLAB/MATLAB_Runtime/v911/runtime/maci64" grasp install_name_tool -add_rpath "/Applications/MATLAB/MATLAB_Runtime/v911/sys/os/maci64" grasp install_name_tool -add_rpath "/Applications/MATLAB/MATLAB_Runtime/v911/extern/bin/maci64" grasp Note that it is not enough to add RPATHs to the auxiliary binary "grasp". They must also be added to the main binary "prelaunch". But why ? 1- Unsigned application using DYLD_LIBRARY_PATH set RPATHs set DYLD_LIBRARY_PATH not set DYLD_PRINT_LIBRARIES ### App running ### 2- Unsigned application with lib tracking set RPATHs set DYLD_LIBRARY_PATH set DYLD_PRINT_LIBRARIES ### App hangs after loading 894 libraries (MatLab has more than 3000 libs and uses many macOS libs) ### The terminal output is a total of 119594 characters. ### Is this more than allowed by `DYLD_PRINT_LIBRARIES`? ### As a consequence the check cannot be completed. Too bad !!! 3- Unsigned application using RPATHs set RPATHs not set DYLD_LIBRARY_PATH set or not DYLD_PRINT_LIBRARIES ### Error: Could not find version 9.11 of the MATLAB Runtime. ### Attempting to load libmwmclmcrrt.9.11.dylib. <-- it does not say "not found"! 307 libs are loaded before this error message occurs 59 are MatLab libs all from /bin/maci64 but the following one is from /runtime/maci64 libmwmclmcrrt.9.11.dylib is the 13th lib loaded and the 6th MatLab one: dyld: loaded: <11D060E5-13C3-34EE-96C9-A7EA2A7E34B3> /Applications/MATLAB/MATLAB_Runtime/v911/runtime/maci64/libmwmclmcrrt.9.11.dylib Note that MacOS does not say "not found" Thus RPATH does not seem to behave exactly as DYLD_LIBRARY_PATH did but why? How can "ignoring DYLD_LIBRARY_PATH" break a library loading ? How can I debug this ? This is very disappointing since, otherwise, the application would easily sign and notarize. I have exhausted all the tracks I knew and found on the internet. Alain

Having set up multiple targets in Xcode (by duplicating the initial one), everything starts off working fine. Then, some reference/inheritance on the "Pod-App" xcconfig files seem to break and pods are no longer found for my second target ("App Staging") resulting in the commonly known "No such module" errors when building. I could nail down the reason in my case but I don't know why it happens or how to fix it (except for going through the whole process again of duplicating the initial target). Also, because there are no changes visible among the project files looking at git. Initial, working state which is always there for my first target and initially also for the second, duplicated target: Then, without purposefully changing anything nor seeing any changes in the project files, the reference to the config files is suddenly missing for the second target. The only thing I imagine doing before that happens, is to build for another device/simulator. Why could this break? How can I link it again to fix the problem?

I have a simple picker with weight selection, but how to write the code to save the selected weightIndex value? I thought of using UserDefaults, but I don't know how to save the numbers. Is there a way that would work please? import SwiftUI struct TestPickerView: View { @State private var weightIndex = 20 @State private var isWeight = false @State private var isExpanded = false var Weight = Array(20...180) var body: some View { NavigationView { List { DisclosureGroup("Weight: \(weightIndex) kg", isExpanded: $isWeight) { VStack { Picker("", selection: $weightIndex) { ForEach(Weight, id: \.self) { Text("\($0.formatted(.number.grouping(.never)))") } } }.pickerStyle(WheelPickerStyle()) } } } } } struct TestPickerView_Previews: PreviewProvider { static var previews: some View { TestPickerView() } } Does anyone know how to save the selected weight number and save it?

If possible, I am trying to create a tuple where one of the values can be modified and used for the expected argument Binding. Can this be done? Thank you.

Hi, we are building an app to sync contacts for event organization. The app can sync between 100 to 1000 contacts to the Contacts app of iOS. We can't manage the device because the user can bring their own device. We are currently facing an issue with thirdparty application like Whatsapp/Signal/Telegram because they sync the contacts from and to the phone. When the sync is enabled in one of this app we can't delete all the contacts at the end of the event because they are synced back to the Contacts app. When we update the contact it also get messed up by those apps. Do you know an workaround to prevent this scenario? Is it possible to prevent thos apps to sync a contact?

Hi, I have installed tensorflow-macos on an apple-silicon machine, but I am unable to correctly install tensorflow-datasets. Here what I am doing: conda create -n myenv python=3.10 -c conda-forge conda activate myenv conda install -c apple tensorflow-deps python -m pip install tensorflow-macos python -m pip install tensorflow-metal python -m pip install tensorflow-datasets Here I run into an error: ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts. tensorflow-macos 2.11.0 requires protobuf<3.20,>=3.9.2, but you have protobuf 3.20.3 which is incompatible. Successfully installed click-8.1.3 dm-tree-0.1.8 etils-1.0.0 googleapis-common-protos-1.58.0 importlib_resources-5.12.0 promise-2.3 protobuf-3.20.3 psutil-5.9.4 tensorflow-datasets-4.8.3 tensorflow-metadata-1.12.0 toml-0.10.2 tqdm-4.64.1 zipp-3.15.0 I am also trying to install KerasCV with Custom Ops from source and I run into the same dependency error on protobuf. It seems that one of the dependencies of tensorflow-datasets and KerasCV requires protobuf 3.20, which in turn is not compatible with my version of tensorflow-macos. If I try to downgrade protobuf to version 3.19.4 I get: ERROR: pip's dependency resolver does not currently take into account all the packages that are installed.

How can I restore a certificate?

Is it possible to open a Keynote file in the iOS-Keynote App from my app? I tried with shortcuts, but do not know how to pass the file as input. I took the shortcut "Open Presentation" to open a file with Keynote, but it does not take my file as input. It always asked "Which presentation?" if I run this code: NSString *shortcutURL = [NSString stringWithFormat:@"shortcuts://run-shortcut?name=%@&input=%@", myShortcutName, filePathToKeynote]; [[UIApplication sharedApplication] openURL:[NSURL URLWithString:shortcutURL] options:@{} completionHandler:nil]; Is there any other option to directly open the file in Keynote without showing a dialog where the user has to pick the Keynote App first? I know it's possible with UIActivityViewController, but I want to avoid showing the dialog where the user has to choose the application.
