CoreData context returns nil after setting it up

I'm trying to set up coreData but for some reason my context returns nil making it impossible to store, fetch or save data. I have used the same context code in another project an it works fine, so not sure what's up this time. The context looks like this: 

func getContext() -> NSPersistentContainer {
    let persistentContainer: NSPersistentContainer = {
    let container = NSPersistentContainer(name: "MyContainer")

        container.loadPersistentStores(completionHandler: { (storeDescription, error) in
            if let error = error as NSError? {
                fatalError("Unresolved error \(error), \(error.userInfo)")
            }
        })

        return container
    }()
    return persistentContainer
}

Then in viewWillAppear

context = getContext().viewContext
print("🙊", context) //This is nil

So what am I doing wrong? Can the naming of the container be whatever I want or does it has to be something specific?

Name should be the same as .XCDataModel file in your project.

Documentation

How File looks like

In this case you should create container in that way: let container = NSPersistentContainer(name: "CardGenerator")
