I'm developing an app which uses CoreData and is already released. I'm trying to add syncing feature using iCloud and Ensembles 1.x. I added codes which are told in the readme, but syncing doesn't happen. The debug log says it can't leech to ensemble.
I enabled iCloud for the project, but only for Key-value storage which is used for another purpose. Do I need to enable other services such as iCloud Documents or CloudKit?
Also, I have this line like sample codes do, and wondering ubiquityContainerIdentifier shouldn't be nil. But I have no idea what I should pass. Could you please give me any advices?
cloudFileSystem = CDEICloudFileSystem(ubiquityContainerIdentifier: nil)
Thank you in advance.
