Is there an existing issue?

• I have searched existing issues

Build info

• objectbox version: 4.3.0
• Flutter/Dart version: dart 3.6.0 flutter 3.27.1
• Build OS: macOS 14.7.6
• Deployment OS or device: many: iPhone 16 Pro 18.5.0, iPhone 13 Pro 16.2.0, iPhone 15 Pro 18.5.0 and so on

Steps to reproduce

Basically it is happens on the store opening, we open the store on the app startup

Expected behavior

Want no crashes

Actual behavior

It crashes

Code

Code

Store store;
final dir = await defaultStoreDirectory();
try {
  if (obx.Store.isOpen(dir.path)) {
    store = obx.Store.attach(getObjectBoxModel(), dir.path);
  } else {
    store = await openStore(directory: dir.path);
  }
} catch (e) {
  dir.deleteSync(recursive: true);
  store = await openStore(directory: dir.path);
}

Thanks for reporting. As this is very similar to the macOS issue: does the app work when run on the simulator in debug configuration, without code signing? If so, then this may be an issue with iOS app entitlements. Maybe then Apple's resources can help you diagnose this: https://developer.apple.com/documentation/bundleresources/diagnosing-issues-with-entitlements

[greenrobot-team]

Maybe also double-check that everything required to publish a Flutter app for iOS is set up in Xcode: https://docs.flutter.dev/deployment/ios#review-xcode-project-settings

[greenrobot-team]

After researching this a bit: it appears it's also possible to create an app group on Apple mobile devices like iOS.

For macOS sandboxed apps these are required to enable IPC (like POSIX semaphores, used by mutexes in the ObjectBox database library, but only on macOS), so the Store constructor takes an application group ID to enable this.

An app group allows multiple apps developed by the same team to access one or more shared containers. It also enables additional interprocess communication (IPC) between those apps using Mach IPC, POSIX semaphores and shared memory, and UNIX domain sockets, among other IPC mechanisms. In macOS, app groups can facilitate communication between sandboxed apps, and between sandboxed and nonsandboxed apps. Apps can belong to one or more app groups. You can also use an app group to share data between an app extension or App Clip and its host app.
https://developer.apple.com/documentation/xcode/configuring-app-groups#Overview

Does your app make use of an app group for the iOS build?

I wonder if this then breaks the ObjectBox database library on iOS (maybe because somehow iOS then as well requires semaphore names to be prefixed with the application group ID).

@greenrobot-team thanks for sharing your insights.
This is a production app that is available on the App Store.
Yes we use app groups, the app target shares one group with a live activity target.
There is also another group for OneSignal
