Fantastic work, thank you @jjotaum. I wanted to add HAR support for a long time, but never had the time to address it.
Before I merge it, I just want to confirm that the code in struct HARDocument: Encodable is not a licensed code. Was it created from scratch or taken from somewhere else?

Cool you liked it, it was created from scratch by me based on HAR specs.

Thanks, I'm going to test It soon and release likely together with the preliminary visionOS support being introduced here #239
