Hi Guys,I am testing a document-based CoreData database with iCloud-UIManagedDocument (using Swift 2) but the document it creates is initially a directory with the database files in it. But i’am looking for the single-file type. Does anyone know how to change the internal filewrapper to build a single-file document? One of the problems is that CoreData adds some extra SHM and WAL files from time to time and the second problem is that database files are not just flatfile types.Hope someone can help me out
