I found a playground book from Apple online called "Talking To The Live View". It's an updated playground from the 2016 WWDC. I want to install it on my iPad and try it out. Further, I want to experiment with building my own playground books and installing them on my iPad.
I'm a licensed iOS developer, and know how to install apps on iOS devices, but despite searching for a couple of hours I have not been able to figure out how to install playground books onto my iPad other than the ones that magically get listed from Apple.
