Subclassing NSManagedObject with swift 3 and Xcode 8 beta
<p>I've began to try use Core data with swift 3 and Xcode 8 beta. When I try to generate NSManagedObject subclasses from core data model and Create NSManagedObject subclass… option in Editor menu, Xcode 8 beta generates three files one of them is <strong>_COREDATA_DATAMODELNAME_</strong>+CoreDataModel.swift with the following content:</p>

<pre><code>import Foundation
import CoreData

___COREDATA_DATAMODEL_MANAGEDOBJECTCLASSES_IMPLEMENTATIONS___
</code></pre>

<p>In addition, the content of this file shows two warnings:</p>

<pre><code>Expressions are not allowed at the top level.
Use of unresolved identifier '___COREDATA_DATAMODEL_MANAGEDOBJECTCLASSES_IMPLEMENTATIONS___'
</code></pre>

<p>Has anyones faced the same issue? Which is the meaning of this new file?</p>

<p>Thanks</p>
