WWDC 18: The Pregame Quiz
The Fourth Annual T.T.I.D.G. quiz is here 🎊
It’s Christmas time for iOS engineers the world over. Mr.Cook and friends are a little less than a week away from pulling the curtains off of iOS 12. Will we see vast improvements, or the oft rumored “maintenance” release?
Time will soon tell, but until then it’s time for the fourth annual T.T.I.D.G. WWDC Pregame Quiz!
Participants — time to add the quiz operation to your queues⚡️!
There are three rounds, and the point break down is as follows:
- Round 1–1 point each answer
- Round 2- 2 points each answer
- Round 3- 3 points each answer
The last question of each round is an optional wildcard question. Get it right, and your team gets 4 points, but miss it and the team will be deducted 2 points.
