This is my entry to WWDC 18.
Status Update: Accepted!
The playground is based on a young student who won a scholarship to WWDC. On the way there, the student is stopped by aliens and has to fight them off in order to get to WWDC in time.
The playground uses ARKit so you have to run it on an iPad that is compatible
