Hi @rist thanks for reporting this. Do you have some indication of the frequency of this crash? Are you able to share the schema of the classes that contain embedded objects?
Stating some observations from what I can tell from the stack trace provided, this assertion failure is triggered while writing a new object to the Realm, specifically, setting an non-nullable int property of a linked embedded object. The assertion implies that the incorrect width type is used, though what it actually is I cannot tell. @jedelbo do you have any ideas?
Hi @rist thanks for reporting this. Do you have some indication of the frequency of this crash?
those realm crashes seem to become our most frequent crash in our tvOS app. I see the same crash happening multiple times for a single user.
Are you able to share the schema of the classes that contain embedded objects?
Embedded objects like this https://docs.mongodb.com/realm/sdk/swift/data-types/embedded-objects/ ? I think we don't use that feature.
We have some relations like @objc dynamic var audioTracks = RLMArray<Track>(objectClassName: Track.className()) and some instances where we store String arrays like
final class PlaybackLanguages: Object {
@Persisted(primaryKey: true) var filmId: Int
/// Audio languages stored as comma separated strings
@Persisted var audioOptions: List<String>
…
I need to check but I assume it won't be a problem to share our Realm objects code with you privately
I'll attach more Realm crashes I found
Stating some observations from what I can tell from the stack trace provided, this assertion failure is triggered while writing a new object to the Realm, specifically, setting an non-nullable int property of a linked embedded object. The assertion implies that the incorrect width type is used, though what it actually is I cannot tell. @jedelbo do you have any ideas?
Another important observation - our app is available on iOS and tvOS. We see those crashes only on tvOS even though both releases use the same Realm version and the code for the persistence layer is shared between platforms
It should be noted that the crashes shared above seem to be happening in totally different scenarios. So based on this, I don't have a good guess on what could be wrong here. If we can get a realm file, we might be able to find out more.
Another example of a similar crash:
