This Swift Playground has been developed in Xcode 8.3. It was my scholarship applciation submission for Apple's WWDC 2017. It may a useful teaching resource for teaching early stages of programming. The user is given some pre-implemented methods that they can improve upon. It gives the student the freedom to get creative by developing an robot user to play Battleships.
A number of bots are included in the playground for the user to play against:
SequentialAI- Attacks the board in order A1, B1..J1, A2, etc.RandomAI- Attacks random squares each moveRandomSeekAI- Attacks random squares each move, but attempts to seek and destroys a ship once one has been hit
