Tic-tac-toe Swift playground

This is a Swift playground book that introduces the min-max algorithm. I created this as part of my application for the 2019 Apple WWDC Scholarship.

Using the playground

Open the pre-built tictactoe.playgroundbook using Swift Playgrounds on Mac or Swift Playgrounds on iPad.
Alternatively, build the playground book from source by opening with Xcode and building the PlaygroundBook target, which will produce your playground book as a product. (You can access it by opening the “Products” group in the Project navigator, and then right-clicking and selecting “Show in Finder”. From there, you can use AirDrop or other methods to copy the playground book to an iPad running Swift Playgrounds.)

I used the Swift Playgrounds Author Template provided by apple.
As of now (Nov. 2019), this template fails to compile with Xcode 11.2.1. You need to find the template relevant to your Xcode version and replace the PlaygroundSupport framework before compiling. Alternatively, you can try buidling PlaygroundSupport yourself.
