SwiftUI adding delay to view from inside function call - swiftui

Question

I am trying to code a blackjack deal button where the cards are dealt like so on hitting the button:
Deal face-up card to a player, delay 1 second
Deal face down card to a dealer, delay 1 second
Deal face-up card to a player, delay 1 second
Deal face-up card to a dealer, delay 1 second
My struggle is getting the delays in between each dealt card to make it seem more realistic as opposed to all 4 cards just appearing upon hitting the button. I currently have a deal function defined as so that is called when the deal button is hit:
for dealRound in 1...2{
var dealCard = deck.last
deck.removeLast()
Timer.scheduledTimer(withTimeInterval: 1, repeats: false){ (_) in
player1.hand.append(dealCard!)
}
//player1.hand.append(dealCard!)
switch dealCard!.rank {
case 1:
player1.cardScore += 1
player1.hasAce = true
case 11,12,13:
player1.cardScore += 10
default:
player1.cardScore += dealCard!.rank
}
dealCard = deck.last
deck.removeLast()
Timer.scheduledTimer(withTimeInterval: 1, repeats: false){ (_) in
dealer.hand.append(dealCard!)
}
//If dealRound == 2, dealing upcard to dealer so include that in score
//Otherwise the down card is not included in the score until after the downcard is revealed
if dealRound == 2{
switch dealCard!.rank {
case 1:
dealer.cardScore += 1
dealer.hasAce = true
case 11,12,13:
dealer.cardScore += 10
default:
dealer.cardScore += dealCard!.rank
}
}
}
isDealt = true
}
However, when I hit the deal button, there is a delay and then all 4 cards appear at once. The images for the cards are defined as:
Image(dealer.hand[1].suit.rawValue + String(dealer.hand[1].rank) ).resizable().frame(width:120, height:160).offset(x: 40, y: -40)
I use dealer.hand[0] and player.hand[0] and [1] to show the other cards. The player and dealer are State variables of a Player class. I have tried using DispatchQueue.main.asyncAfter and sleep(1) but have run into similar problems. The only thing I can think to do would be to create 4 separate state Boolean variables and have them set to true after a delay (in a separate function from the deal) so the cards will appear. However, this seems like a poor way of doing it and I feel as though there may be a way similar to what I am trying but can't figure out.
In short: how would I go about adding a delay to an image appearing where the image is dependent on a #State class's array being appended to in a function call?
