This may be a dumb question but I cannot find the 'Playgroundbasics.playground' file nor the folder where i am supposed to download it?I am following the Introduction to Swift and I am on Lesson 1 trying to figure out where to find this folder to download.thank you for the help!

Can anyone give any advice on Apple's policy regarding Amazon gift cards/gift codes, which can be redeemed in-app, based on a virtual currency generated by the User's time spent active on the App. To summarize, user X and user Y play a game and spend 2 hours of time playing. For 2 hours, they generate 10 Diamonds which can be then redeemed for a $10 gift card on Amazon. The user will receive a gift code/card to the email registered to him/her in the game. My understanding is this does not violate section 5.3 of Apple's gambling definition as it is time-based.
