Hi
I really don't understand. I have a record type on CloudKit where I store some data and a corresponding entity on core data that I sync with CloudKit with a very basic routine at some point I call this func:
func GetUserFromCoredata(userID:String)->UserEntity?
{
var fetched:[UserEntity]?=nil
let fetch = NSFetchRequest<UserEntity>(entityName:"UserEntity")
let predicate = NSPredicate(format:"TRUEPREDICATE")
fetch.predicate = predicate
fetch.affectedStores = [DBGlobals.localStore, DBGlobals.cloudStore]
do{
print("RICHIESTA FETCH UTENTI IN COREDATA")
fetched = try context.fetch(fetch)
}
catch{
fatalError("errore nel recupero dell'elenco utenti")
}
if let found = fetched
{
for el in found
{
if el.userID == userID
{
return el
}
}
}
return nil
}
As you can see nothing special. it is only a fetch made on two stores. If I run the code 20 times 19 are good and 1 result in a fatal error with this text:

... and really, I can't understand. the predicate is absolutely basic, the entity exist, here I am not syncing anything, just fetching the records in the two stores... what am I doing wrong? why 19 su 20 are good and one is catching this error?
