Swift: entityForName: could not locate an entity named xxx in this model

I created a test project to fetch data from http://api.androidhive.info/contacts/ everything works fine, but when I try to save the data returned by the web service to a data model entity named ContactDB by
let rowDB = NSEntityDescription.insertNewObjectForEntityForName(NSStringFromClass(ContactDB.self), inManagedObjectContext: moc) as! ContactDB ,

I get this runtime crash: +entityForName: could not locate an entity named 'TestAlamofire5.ContactDB' in this model

I have tried every possible solution mentioned in all related posts in SO:
changed the entity name
prefixed the NSManagedOBject subclass with @objc attribute
deleted the entity and created a new one
deleted the whole data model and created a new one with a new entity
cleaned the project or even created a new project

but to no avail ...

what am i doing wrong to get this crash ?

p.s. the test project can be downloaded here

Also note Xcode can set the Module namespace automatically. I had to delete "Current Product Module" for my Entity to be recognised. Xcode Module

The easiest - and expected - way is to pass the literal name of the entity.

let rowDB = NSEntityDescription.insertNewObjectForEntityForName("ContactDB", inManagedObjectContext: moc) as! ContactDB
