In Feb of 2020, I wrote this post
I have just completed a total (well almost total) rewrite of my PDF code, but now it works for both iOS and macOS from a single project file (try THAT Xojo! 
)
This library will support any font currently installed on the device (desktop or iPhone/iPad)
It supports Unicode characters
It uses a syntax very similar to those commands found in the Xojo Graphics object (except for Object2D)
It is written in 100% Swift with zero external dependecies
The generated PDF document is stored directly to the appropriate /DOCUMENTS folder
here is the basic list of public functions
