Tried for about 40 minutes to get this first Swan’s Quest playground into the Playgrounds app on the iPad. Was never successful. The presentation about this was so well done, I was inspired to learn about Accessibility coding in Swift Playgrounds. Bummed that getting the file was so challenging.

I seemed to have gotten the file in Playgrounds on the iPad. What a convoluted, tortuous path! There has got to be a better way to do this.

I used the Catalina Boot Camp Assistant on my 2020 iMac to set up Boot Camp, install Window 10 Pro, and all the necessary drivers. The Boot Camp Assistant automatically determined what were the correct drivers, and then installed them. Worked the very first time. No problems at all. Your issues might be because you attempted to get the correct drivers manually and "dropped them on the Windows desktop".
