Install Using Swift Package Manager

The Swift Package Manager is a
decentralized dependency manager for Swift.

  1. Add the project to your Package.swift.

    import PackageDescription
    
    let package = Package(
        name: "MyAwesomeProject",
        dependencies: [
            .Package(url: "https://github.com/nvzqz/XO.git",
                     majorVersion: 1)
        ]
    )
  2. Import the XO module.

    import XO

Install Using CocoaPods

CocoaPods is a centralized dependency manager for
Objective-C and Swift. Go here
to learn more.

  1. Add the project to your Podfile.

    use_frameworks!
    
    pod 'XO', '~> 1.0.0'

    If you want to be on the bleeding edge, replace the last line with:

    pod 'XO', :git => 'https://github.com/nvzqz/XO.git'
  2. Run pod install and open the .xcworkspace file to launch Xcode.

  3. Import the XO framework.

    import XO

Install Using Carthage

Carthage is a decentralized dependency
manager for Objective-C and Swift.

  1. Add the project to your Cartfile.

    github "nvzqz/XO"
  2. Run carthage update and follow the additional steps
    in order to add XO to your project.

  3. Import the XO framework.

    import XO

Usage

Game Management

Running a tic-tac-toe game can be as simple as setting up a loop.

import XO

let game = Game()

while !game.board.isFinished {
    let square = ...
    try game.applyMark(to: square)
}

Board Marking

Marks can be applied in a Game instance starting with Mark.x using
applyMark(to:) and its unsafe (yet faster) sibling, applyUncheckedMark(to:).

The mark then switches repeatedly until the game is finished.

Square Availability

The available squares can be retrieved using availableSquares on a Board.

if let squares = game.board.availableSquares {
    for square in squares {
        ...
    }
}

Board Initialization

A board can be created from a two dimensional UnicodeScalar array.

let board: Board = [["x", " ", "o"],
                    [" ", " ", "x"],
                    ["x", " ", "o"]]

A board can also be created from a hash value. Hash values do not change across
processes.

let other = Board(hashValue: board.hashValue)

other == board  // true

Board Transformations

Board Flipping

The flippedHorizontally() method returns the board with its left side swapped with its right side.

The flippedVertically() method returns the board with its top side swapped with its bottom side.

There is also flippedHorizontallyAndVertically() which efficiently produces the same result
as calling both flippedHorizontally() and flippedVertically().

Board Rotating

The rotatedLeft(by:) and rotatedRight(by:) will return the result of rotating the board left or
right count times.

The parameter can be of any type conforming to ExpressibleByIntegerLiteral and IntegerArithmetic.

Pretty Printing

print(board.ascii)
x  .  o
.  .  x
x  .  o

print(board.emoji)
