I'm working on a RoomPlan app. I've successfully managed to capture, save and load scans using NSKeyedArchiver. However, for apps run on the simulator or on devices without a LiDAR Scanner, I do not have any scans saved on that device so I cannot test the functionality. I want to "fill" my app with a test scan or two to be able to test my app on those devices.

The core problem here is that I can't figure out how to "capture" objects in Swift and save them hardcoded in the app instead of in NSKeyedArchiver, which is local to every device.

You are doing this:

• RoomScan --(via NSKeyedArchiver/Encodable)--> Data --(save)--> UserDefaults
  
• UserDefaults --(read)--> Data --(via NSUnarchiver/Decodable)--> RoomScan

So, what I suggest:
Scan a room, then convert it as Data, save it if needed. Intercept that Data either by forcing a reading, or before saving into UserDefaults.

Choose the solution you find easier/quicker for you for the "intercept":
Convert the Data into HexString (see How to convert Data to hex string in swift), print it into Console, copy the output or save maybe that content into a Data file, and send it via AirDrop/Mail.

Create a new file into your project, and read it when needed (simulator, etc). Depending on the solution chosen since the writing might differ, the reading also might differ.
