Summary:
Versions: Xcode: Version 6.0 (6A280e), OS X: 10.10 (14A298i)

The Swift, non-storyboard, document-based application template does not produce apps that function immediately.

Steps to Reproduce:
Steps to Reproduce:
Install and open Xcode 6A280e under OS X 10.10 (14A298i).

Create a new Cocoa Application.
Enter Any Product Name, Organization Name, Organization Identifier.
Select Swift as the language.
Uncheck “Use Storyboards”.
Check “Create Document-Based Application”.
Enter any Document Extension.
Uncheck “Use Core Data”.

Create the project in an auspicious location on disk.

(Alternatively: download the attached Demo.zip, extract its contents, and open the enclosed Xcode project.)

Run the app.

You will see an alert with the text “No document could be created.

You will see in the console <<2014-09-01 16:35:22.463 Demo[39748:12877248] The DocumentType type doesn't map to any NSDocumentClass.>>


Expected Results:
A new Document window should appear when the app launches for the first time or whenever you select "File"->"New".

Actual Results:
When the app launches for the first time, and thereafter whenever you select "File"->"New", an alert is presented with the text "No document could be created." and into the console is logged "The DocumentType type doesn't map to any NSDocumentClass.".

Notes:
There are a couple of workarounds:

(1)  Override readableTypes() in Document.swift:

    override class func readableTypes() -> [AnyObject] {
        return ["DocumentType"]
    }

(2)  In the Info.plist, change the entry for "Document Types"->"Item 0"->"Cocoa NSDocument Class" to the mangled version of "$(PRODUCT_MODULE_NAME).Document" (for example "_TtC4Demo8Document").

It looks like the immediate cause of the bug is in the implementation of -[NSDocumentController _getReadableNotWritable:types:forDocumentClass:] where the unmangled "Demo.Document" is compared via isEqualToString: to the mangled "_TtC4Demo8Document" with predictable results.
