IOS Swift 2.0 Card shuffling function

Question

Noob here, I am trying to create a card game using a standard deck of 52 cards. Here is the code I would like to make into a func so I dont have to manually write it out every single time. I am creating 5 different players so this would be replicated to other players.

func firstPlayerCardShuffle() {
var firstPlayerCard1Num = (Int(arc4random_uniform(UInt32(13)) + 2))
var firstPlayerCard1Suit = suits[Int(arc4random_uniform(UInt32(suits.count)))]
var firstPlayerCard1 = "\(firstPlayerCard1Num) of \(firstPlayerCard1Suit)"

var firstPlayerCard2Num = (Int(arc4random_uniform(UInt32(13)) + 2))
var firstPlayerCard2Suit = suits[Int(arc4random_uniform(UInt32(suits.count)))]
var firstPlayerCard2 = "\(firstPlayerCard2Num) of \(firstPlayerCard2Suit)"

return(firstPlayerCard1,firstPlayerCard2)
}

Can someone let me know what I'm missing.

There are a _lot_ of card-shuffle Swift implementations shown on Stack Overflow. Please search before asking. — matt, Mar 10 '16 at 18:05

Not a direct answer to your question, but I think you'll want something like this:

enum Number: String {
    case Two = "two"
    case Three = "three"
    case Four = "four"
    case Five = "five"
    case Six = "six"
    case Seven = "seven"
    case Eight = "eight"
    case Nine = "nine"
    case Ten = "ten"
    case Jack = "jack"
    case Queen = "queen"
    case King = "king"
    case Ace = "ace"

    static var randomNumber: Number {
        return [Two, Three, Four, Five, Six, Seven, Eight, Nine, Ten, Jack, Queen, King, Ace][Int(arc4random_uniform(13))]

    }
}

enum Suit: String {
    case Spades = "spades"
    case Hearts = "hearts"
    case Diamonds = "diamonds"
    case Clubs = "clubs"

    static var randomSuit: Suit {
        return [Spades, Hearts, Diamonds, Clubs][Int(arc4random_uniform(4))]
    }
}

struct Card: CustomStringConvertible, Equatable {
    let number: Number
    let suit: Suit

    var description: String {
        return "\(number.rawValue) of \(suit.rawValue)"
    }

    static var randomCard: Card {
        return Card(number: Number.randomNumber, suit: Suit.randomSuit)
    }

    static func randomCards(count count: Int) -> [Card] {
        guard count > 0 else {
            return []
        }
        guard count <= 52 else {
            fatalError("There only are 52 unique cards.")
        }
        let cards = randomCards(count: count - 1)
        while true {
            let card = randomCard
            if !cards.contains(card) {
                return cards + [card]
            }
        }
    }
}

func == (left: Card, right: Card) -> Bool {
    return left.number == right.number && left.suit == right.suit
}

let randomCards = Card.randomCards(count: 5)
print(randomCards)
// prints five random cards

Let me know if you have any other questions.

This might return the same card to more than one player and thats probably not what the OP wants. He said a deck of 52 cards — Leo Dabus, Mar 10 '16 at 18:16
