I can't create a empty array property in a class in Swift

Question

I want to create a class in Xcode Swift see this code:

class Cards {

    var roundNumber = 10
    var monsters:[
        (Id: Int, Name:String, Description: String, Attack_min: Int, Attack_max: Int, Health: Int, VP: Int, Gold:Int)] = [
        (Id: 1, Name: "Ice dragon", Description: "Attack on Wizards +1", Attack_min: 2, Attack_max: 5, Health: 4, VP: 2, Gold: 4),
        (Id: 2, Name: "Fire dragon", Description: "Attack on Wariors +2", Attack_min: 2, Attack_max: 5, Health: 4, VP: 2, Gold: 4),
        (Id: 3, Name: "Acid witch", Description: "Attack of all heroes -1 \n(Only -1 on heroes)", Attack_min: 3, Attack_max: 6, Health: 5, VP: 4, Gold: 5),
        (Id: 4, Name: "Killer rats", Description: "Health -1 when attacked by supporting cards ", Attack_min: 2, Attack_max: 6, Health: 3, VP: 1, Gold: 3)
    ]
   var monsterDeck = [Any]()

    func randomizer(lowestNumber: Int, highestNumber: Int) -> Int {
        return Int.random(in: lowestNumber ... highestNumber)
    }

    func round() {
        if self.roundNumber == 10 {
            self.monsters.shuffle()
            self.monsterDeck = self.monsters
        } else {
            self.monsterDeck.removeFirst()
        }

        self.roundNumber -= 1
    }
}

var cards = Cards()
cards.round()

print("\(cards.monsterDeck[0].Name)\n")
print(cards.monsterDeck)
print(cards.roundNumber)

var monsters is a array that I going to update myself I want to shuffle the cards and store it in var monsterDeck

what I want is that every time I run the function round() I want a new monster card that is shuffled and the first array of monsterdeck should be removed.

But at the bottom you see print("\(cards.monsterDeck[0].Name)\n") and for that I get an error:

error: MyPlayground.playground:34:31: error: value of type 'Any' has no member 'Name'
print("\(cards.monsterDeck[0].Name)\n")

So how can I fix this? Basicly I want the var monsterDeck to be a array that is a shuffled version of array monsters

I checked this article, but those answers assumed the array would be only string or int.

My example has string and int fields

Use structs, not tuples for your Monster data, and then create an array of those structs:

var monsterDeck = [Monster]()

By using Any as the type, you're losing all the detail information about what's in the deck.
