IPhone : What platform should I use if I wanted to create a multiplayer game?

I'm writing a multiplayer card game in Swift, where for example if 2 players are playing, each player will have a different screen. Like for example, I'm using 2 set of cards of 2 different colors: 4 in each. I generate the cards randomly, to the players. if one player has 3 blue card and a red one on his screen, the second player will have 3 blue cards and 1 blue card showing on his screen
