I'm developing a Multiplatform app that uses CloudKit to sync the CoreData between the user's devices. At this time they don't share data between users. I have a single password field on a single Entity and was wondering if there was a simple way to encrypt just this field. I see in CoreData there's a checkbox labelled "Allows Cloud Encryption"... does checking that off magically encrypt it. I checked it off and nothing seemed to change so I unchecked it for now... is there something else I needed to do? And, most importantly, will it work with CloudKit?
Yes, checking that box encrypts the data on CloudKit. You can learn more about it here https://developers.apple.com/videos/play/wwdc2021-10015/?time=1285
BUT, you might consider storing passwords in the Keychain instead.
