Sandbox-friendly installation of NSRecentDocumentsMenu without Nib - objective-c

Question

I am working on a project that does not (currently) use any nib files at all.
I'm trying to figure out whether there is any way to add the NSRecentDocumentsMenu Open Recent menu that doesn't require use of a private API.
The below link is all I've managed to find thus far:
http://lapcatsoftware.com/blog/2007/07/10/working-without-a-nib-part-5-open-recent-menu/
Can anyone offer insights?

I'm trying to figure out whether there is any way to add the NSRecentDocumentsMenu Open Recent menu that doesn't require use of a private API.
The following link is for a document-based app in swift without using nibs:
https://www.dropbox.com/s/cfvsz11oe00lnp5/DocBased_swift.zip?dl=0
It uses a modification of menu code found in this reference:
https://talk.objc.io/episodes/S01E145-setting-up-a-document-based-app
The demo may be run in Xcode by creating a macOS app using swift and a XIB interface, although we will not use the XIB. Create a new file called main.swift and remove the existing AppDelegate class. Copy/paste the source code found above into the main.swift file (use import Cocoa instead of Foundation). When you hit the Run button you will notice that the menus are grayed out and there is no Open Recent menu item. To fix this be certain to add Cocoa NSDocument Class and Role to the info.plist (see image in folder above). The Cocoa NSDocument Class should be the nameOfYourApp.Document for swift or just plain Document for objc. When the Run button is hit after making these additions you should have a document based app with a functioning Open Recent menu item. Please post followup if there are problems.
Objc source code is here:

Instructions are similar to those for swift, except a macOS app is created using objective-c. Copy/paste the source code into main.m after deleting what Xcode supplied. For simplicity, also remove AppDelegate and the Document class (if you checked 'Document based' in the setup), although you could use them if you so desire. The info.plist will also have to be amended with the two additions as noted above.
