Hey @dev52,
I'd recommend that you get started with various pathways that you find reverent to your journey. In particular you might want to look at the Design, visionOS, and Enterprise pathways. These pathways are easy-to-navigate collections of videos, documentation, and tools.
Additionally you might want to watch some prior WWDC session videos available here.
There is a lot of documentation, sample code, and videos to uncover. Let me know if you have any questions. If you have a specific issue that you need assistance with, please open up a new thread.
Thanks,
Michael
