Prior to calling the
dequeue method of the collection view, you must use this method or the
register(_: method to tell the collection view how to create a supplementary view of the given type. If a view of the specified type is not currently in a reuse queue, the collection view uses the provided information to create a view object automatically.
If you previously registered a class or nib file with the same element kind and reuse identifier, the class you specify in the
view parameter replaces the old entry. You may specify
nib if you want to unregister the class from the specified element kind and reuse identifier.
