### Create Standard Chess Board

Source: https://github.com/chesskit-app/chesskit-swift/blob/master/README.md

Initializes a new ChessKit Board object with the standard chess starting position.

```swift
let board = Board()
```

--------------------------------

### Move Piece on Board

Source: https://github.com/chesskit-app/chesskit-swift/blob/master/README.md

Moves a chess piece on the board from a starting square to a destination square. This operation updates the board state.

```swift
let board = Board()
// move pawn at e2 to e4
board.move(pieceAt: .e2, to: .e4)
```

--------------------------------

### Get Legal Moves for Piece

Source: https://github.com/chesskit-app/chesskit-swift/blob/master/README.md

Retrieves a list of all legal moves for a specific piece at a given square on the board. Useful for AI or move generation.

```swift
let board = Board()
print(board.legalMoves(forPieceAt: .e2))    // [.e3, .e4]
```

--------------------------------

### Import ChessKit

Source: https://github.com/chesskit-app/chesskit-swift/blob/master/README.md

Import the ChessKit library to use its functionalities in your Swift code. This is a prerequisite for all ChessKit operations.

```swift
import ChessKit
```

--------------------------------

### Parse Chess Notation

Source: https://github.com/chesskit-app/chesskit-swift/blob/master/README.md

Parses various chess notation formats (FEN, PGN, SAN) into their corresponding ChessKit objects (Position, Game, Move). Also demonstrates converting objects back to their string representations.

```swift
// parse FEN using Position initializer
let fen = "rnbqkbnr/pp1ppppp/8/2p5/4P3/5N2/PPPP1PPP/RNBQKB1R b KQkq - 1 2"
let position = Position(fen: fen)

// convert Position to FEN string
let fenString = position.fen

// parse PGN using Game initializer
let game = Game(pgn: "1. e4 e5 2. Nf3")

// convert Game to PGN string
let pgnString = game.pgn

// parse the move text "e4" from the starting position
let move = Move(san: "e4", in: .standard)

// convert Move to SAN string
let sanString = move.san
```

--------------------------------

### Create Chess Board from FEN

Source: https://github.com/chesskit-app/chesskit-swift/blob/master/README.md

Creates a ChessKit Board object from a FEN (Forsyth–Edwards Notation) string. Ensure the FEN string is valid for correct initialization.

```swift
if let position = Position(fen: "rnbqkbnr/pp1ppppp/8/2p5/4P3/5N2/PPPP1PPP/RNBQKB1R b KQkq - 1 2") {
    let board = Board(position: position)
    print(board)
}
```

--------------------------------

### Check Move Legality

Source: https://github.com/chesskit-app/chesskit-swift/blob/master/README.md

Checks if a specific move is legal on the current board state. Returns a boolean indicating legality.

```swift
let board = Board()
print(board.canMove(pieceAt: .a1, to: .a8)) // false
```

--------------------------------

### Check Board State

Source: https://github.com/chesskit-app/chesskit-swift/blob/master/README.md

Determines the current state of the chess game, such as active, check, stalemate, or checkmate. The state is updated after each move.

```swift
let board = Board(position: .init("8/5K1k/8/4Q3/8/8/8/8 w - - 0 1")!)
// 8 · · · · · · · ·
// 7 · · · · · ♔ · ♚
// 6 · · · · · · · ·
// 5 · · · · ♕ · · ·
// 4 · · · · · · · ·
// 3 · · · · · · · ·
// 2 · · · · · · · ·
// 1 · · · · · · · ·
//   a b c d e f g h

print(board.state) // .active (default)
board.move(pieceAt: "e5", to: "g7")
print(board.state) // .checkmate(color: .black)
```
