SwiftChess is a chess engine written in Swift.
![swiftchess](https://cloud.githubusercontent.com/assets/6288713/24018928/d90f9182-0a8d-11e7-808c-a96bcb998462.gif)
Rather than a library that you can call to assist in making valid chess moves, SwiftChess aims to be a complete chess game, minus the UI.
## Features
SwiftChess also includes a complete AI implementation.
- Move validation
- AI with three difficulty levels
- Callbacks for check, checkmate and stalemate
- Supports castling
- Supports En Passent
- Supports pawn promotion
- Asyncronous AI move calculation
There's no documentation for now, as the public api is still in flux, but there is a complete example project for iOS.
SwiftChess doesn't provide any UI, just all of the logic required to create a chess game. The example project contains a complete UIKit UI with touch handling that you start from if you like.
SwiftChess also has a reasonably comprehensive set of unit tests.
## Example
The example application contains a complete implementation of **SwiftChess**.
Run `Example/Example.xcodeproj`
## Basic Use
##### Start a game
```
// Make a human player
let whitePlayer = Human(color: .white)
// ... or an AI Player
let blackPlayer = AIPlayer(color: .black, configuration: AIConfiguration(difficulty: .hard))
// Create a game
let game = Game(firstPlayer: whitePlayer, secondPlayer: blackPlayer)
```
##### Make a move
```
if let player = game.currentPlayer as? Human {
let currentLocation = BoardLocation(x: 4, y: 1)
let newLocation = BoardLocation(x: 4, y: 2)
try! player.movePiece(from: currentLocation,
to: newLocation)
}
```
##### Tell the AI to make a move
```
if let player = game.currentPlayer as? AIPlayer {
player.makeMoveAsync()
}
```
##### Then just wait for the callbacks!
```
extension GameViewController: GameDelegate {
func gameDidMovePiece(game: Game, piece: Piece, toLocation: BoardLocation) {
// Move piece on board
}
func gameDidRemovePiece(game: Game, piece: Piece, location: BoardLocation) {
// Remove piece from board
}
func gameDidTransformPiece(game: Game, piece: Piece, location: BoardLocation) {
// A pawn was promoted!
}
func gameWonByPlayer(game: Game, player: Player) {
ShowAlert("Checkmate!")
}
func gameEndedInStaleMate(game: Game) {
ShowAlert("Stalemate!")
}
func gameDidChangeCurrentPlayer(game: Game) {
// Make another move
}
}
```
## Persistence
The entire state of a **SwiftChess** game can be converted to and initialised from a `Dictionary`.
Get a snapshot of the current state:
```
let dictionary: [String: Any] = game.dictionaryRepresentation
```
Initialise a game with a previous snapshot:
```
let game = Game(dictionary: dictionary)
```
The returned dictionary stores all the information required to create a 'save game' feature. The player colors, AI difficulty, piece positions etc.
You can serialize this to JSON, save it to disk, send it over the network etc.
## Other stuff
##### Make a castling move
```
if game.board.canColorCastle(color: .white, side: .kingSide) {
player.performCastleMove(side: .kingSide)
}
```
##### Support pawn promotion
```
func promotedTypeForPawn(location: BoardLocation,
player: Human,
possiblePromotions: [Piece.PieceType],
callback: @escaping (Piece.PieceType) -> Void) {
// Show UI for the user to select one of the possible promotion types
// then call the handler
// ...or some games just promote to a queen
callback(.queen)
}
```
The example app can run *player vs player*, *player vs AI*, *AI vs AI* matches
