You start with a library of Cards, Decks, and Hands, and XCTest tests covering those classes. Example usage you can find below.
Your goal is to extend this library to support a variant of Poker called Texas Hold 'em.
This game will be made of a TexasHoldemDealer, TexasHoldemPlayers, and their PokerHands.
You do not need to make a Texas Hold 'em app, with any UI or controllers.
You only need to make the provided XCTests pass, with clean and well-factored code.
You are given failing XCTest tests for each of these classes.
Run tests in XCode with Product -> Tests (⌘+U) to run all tests,
or click the test icon in the sidebar (fifth icon, looks like a yield sign) and hover over any individual test to run it.
You can also run individual tests from the test files themselves, which live under the Texas Hold'emTests folder in the project navigator.
These tests should encode all the knowledge of Poker and Texas Hold'em you need for this problem, so don't worry if you're not a poker expert. If you would like more information to feel comfortable, the sections "Poker Hand Rankings" and "The Play" at this site (ignoring "1. Posting the Blinds" and all other such mentions of betting) should be all you need to know. Wikipedia, as always, is also a pretty good, if at times overly detailed, resource: List of Poker Hands and Texas Hold'em : Play of the Hand.
Just run the XCode project and you should be good to go!
Here's a trivial example of declaring a new deck, shuffling, and drawing 5 cards into a hand:
import "Hand.h"
import "Deck.h"
...
Card *aceOfSpades = [[Card alloc] initWithRank:CardRankAce andSuit:CardSuitSpades;
Card *queenOfHearts = [[Card alloc] initWithRank:CardRankQueen andSuit:CardSuitHearts;
Hand *hand = [[Hand alloc] initWithCards:@[aceOfSpades, queenOfHearts]];
Deck *deck = [[Deck alloc] init];
[deck shuffle];
[hand drawCards:5 fromDeck:deck];
NSLog(@"%@", hand);
...
