How I can export PKDrawing?

In this video Will said that he drew alphabet letters and somehow exported it in .drawing format? How can I do it, for example with sample app?

I can make PKDrawings there but didn't find out how to export this PKDrawing in .drawing format

I will answer to my question by myself. Basically, what you need to do is to save your drawing in .data format. I choose to save it in .data in documents folder, then you can export it and load with PKDrawing(data: yourDataName).
However, I didn't figure out how to make .drawing file
