[realm-cocoa] Can't set primary key property 'id' to existing value 'temporaryID'

class BDRHomeView: Object {
......
let events = List<BDRHomeEvent>()
dynamic var id = "temporaryID"
override class func primaryKey() -> String? {
return "id"
}

realm.create(BDRHomeView.self, value:response, update:true)

here is the error :
*** Terminating app due to uncaught exception 'RLMException', reason: 'Can't set primary key property 'id' to existing value 'temporaryID'.'
could you help me? and I use Realm-Swift 0.96.3

Can you show us where the variable response is coming from and some more context around that code and share the full stack trace?

Because there is no primary key given in the value, it is assuming that a new instance should be created. That doesn't cover your case, where a default instance exists implemented via the default value of the primary key. I'd suggest that you open up an issue on our repo, so that we can discuss over there how that case should be handled. We could at least fail more graceful, when we decide that there are good reasons against supporting that.

Are you sure that the exception you're facing is originating from that particular line. Or do you have perhaps somewhere else some code around where you modify the id property of an already persisted object?
