Hello Apple Developer Community,
I am encountering an issue with app icon rendering after updating an app on devices running iOS 18 or newer. Below are the details:
Issue Summary:
When updating an app from a previous version (with separate light and dark mode icons) to the latest version (where both modes use the same icon), the icon changes are not reflected consistently across all system menus.
Steps to Reproduce:
- Set the device mode to Dark Mode.
- Install the previous app version (with different icons for light and dark modes).
- Update the app to the latest version (where both modes use the same icon).
- Change the device mode to Light Mode.
- Switch back to Dark Mode.
Expected Behavior:
The app icon should remain consistent across all system menus (Home Screen, Spotlight search, etc.) when switching between Light and Dark Modes.
Observed Behavior:
- The app icon displays correctly on the Home Screen but inconsistencies appear in other menus, such as Spotlight search or when toggling between modes.
- For instance, in Dark Mode, the icon may revert to the previous black-colored logo or display incorrectly compared to the updated design.
Additional Notes:
- The asset catalog is configured correctly, with identical icons set for both light and dark modes in the latest app version.
- Incrementing the build number was implemented during the update.
- A manual device restart resolves the issue on some devices, but not consistently.
Questions for the Community:
- Has anyone else experienced similar app icon caching or rendering issues in iOS 18 or later?
- Are there known workarounds or specific configurations to ensure consistent icon rendering across all system menus?
- Could this be related to iOS 18's icon caching or appearance handling mechanisms?
Your insights and suggestions would be greatly appreciated. Thank you for your time!
