A good approach for storing the database in a shared AppGroup container
I am using Realm in my application as a database and I have a sharing extension to support multimedia to be shared with another application. Since I need my database to be accessed from the share extension, I moved the realm file from the application document directory to the shared Appgroup container. I have some questions.
- Is it safe to store the database in the shared container space.
- When I remove the app, the files inside the shared container are saved, so when the shared container is removed.
- Any other advice on handling my script.

It looks like you have cross-posted this on the Realm GitHub issue tracker. My comment from https://github.com/realm/realm-cocoa/issues/4899#issuecomment-297121059 was posted here for your convenience:
- Is it safe to store the database in the shared container space.
Yes. This is actually the only way to share files between processes on iOS.
- When I remove the app, the files inside the shared container are saved, so when the shared container is removed.
According to fooobar.com/questions/381421 / ... , iOS removes shared containers as soon as the last app has access to it is removed from the device.
If you find situations where this does not happen, I recommend that you file a radar to report the bug to Apple. https://bugreport.apple.com
- Any other advice on handling my script.
It looks like you are doing everything right. Keep it up! 👌
