Both custom and generated objectId in one project

I was thinking that if the object does not exist in database and I do not specify an objectId then the save function will assign some to it. Please, confirm, that it is not possible to use both, so that I would switch all objects to automatic objectId. Otherwise I think it could be just SDK blocking that save operation?

It is not recommended to do both as the Swift SDK nor any of the other client SDK’s support it. You should either:

1. Let the server generate 100% of the objectId’s
2. Generate 100% of the objectId’s on the client with customObjectIds enabled and then save

The server does support a mixed environment, but my guess is this done when using different clients, Swift SDK generating own objectIds, Android SDK doesn’t generate own objectIds. Another scenario is supporting multiple versions of a particular SDK
