We are experiencing an issue where our app gets stuck during launch. The splash screen appears for some time, and then the app either becomes unresponsive or closes unexpectedly. However, there are no crash logs captured in Xcode or Firebase Crashlytics, indicating that the app is not crashing but rather being terminated. This issue is preventing affected users from properly launching the app.
Additionally, some users have reported occasional lag and slow performance when using the app. The issue occurs only for a specific subset of users and appears to be related to other Electronic Logging Device (ELD) apps running in the background. When these apps are active, our app struggles to launch and sometimes becomes unresponsive.
We suspect that this behavior could be related to system resource allocation, such as high memory consumption by background apps, which might be affecting our app's ability to launch correctly. However, we have been unable to reproduce the issue on our end despite multiple attempts.
Actions Performed During App Launch:
- Firebase configuration
- API requests, including:
- Fetching account details
- Registering the FCM token with the server
- Asynchronous background requests to fetch POI details
- Creating a local database and storing POI data in local storage
We would like guidance from Apple regarding potential causes and debugging strategies, especially in scenarios where the app does not produce crash logs but still fails to launch properly. Any insights into memory management, conflicts with background applications, or system resource constraints would be highly appreciated.
- Steps to Reproduce:
- Install and launch the app on an affected device.
- Observe that the app gets stuck on the launch screen.
- After some time, the app terminates unexpectedly.
- Issue is inconsistent and occurs only for certain users.
- Presence of other ELD apps running in the background appears to influence the issue.
