I started my adveture with Swift Playgrounds last Sunday mainly because of #stayhome. First on a iPad Mini, then on iPad Pro 12.9. Yesterday I tried on my late 2013 i7 MBP, but the fans were turning like crazy. So I tried another setup:
iPad Pro 12.9 with a HDMI monitor, USB keyboard and USB mouse connected all via USB-C dongle. It seem to work 🙂 >
