Set a managed object context’s transactionAuthor before saving it to differentiate among multiple call sites that modify the same context. Doing this records an author in subsequent transactions.
func addColor(_ name: String, in context: NSManagedObjectContext) {
let color = Color(context: context)
color.name = name
color.creationDate = Date()
// set the transaction author
context.transactionAuthor = "addColor"
persistentContainer.saveContext(context)
context.transactionAuthor = nil
}Reset the context’s transactionAuthor to nil after the save to prevent misattribution of future transactions.
