I have an app that uses a Share Extension that allows the user to share videos, from Files and Photos etc., the video URL and some related data is then persisted with SwiftData and synchronized with CloudKit.
This code has worked consistently for a long time although recently, with iOS 26 and recent builds of iOS 18, I have observed that the video is either not saved to SwiftData (iOS 26.0), or available locally when the app is opened on the same device where the share occurred, but not synchronized to other devices (iOS 18.7 and iOS 26.1 beta).
Assuming the video is opened locally after being shared into the app, it is typically synchronized with CloudKit to other devices although it's not as reliable as it should be.
Is there a reliable approach in the Share Extension to ensure that the data is saved to the local SwiftData database and then synchronized with CloudKit. I suspect it could be that the lifetime of the Share Extension has become even more constrained in recent OS updates that the process ends before it has the opportunity to save and synchronize the data.
Any thoughts on how to ensure this is reliable would be greatly appreciated.
The data saved is not too large as it consists only of the video URL and not the data of the video itself.
