Title: Name of book: description (page number)

Why isn’t:

if let localPlayer = gameCenterData?.getLocalPlayer() {
  if let index = gameCenterData?.getPlayerIndex(for: localPlayer) {
    gameCenterData?.players[index].totalPoints =
      gameModel.players[0].totalPoints
}
// Update the remote player's stats
if let remotePlayer = gameCenterData?.getRemotePlayer() {
  if let index = gameCenterData?.getPlayerIndex(for: remotePlayer) {
    gameCenterData?.players[index].totalPoints =
      gameModel.players[1].totalPoints
} 

just:

// Update the local player's stats
if let localPlayer = gameCenterData?.getLocalPlayer() {
   localPlayer.totalPoints = gameModel.players[0].totalPoints
}
// Update the remote player's stats
if let remotePlayer = gameCenterData?.getRemotePlayer() {
    remotePlayer.totalPoints = gameModel.players[1].totalPoints
} 

Am I missing something special that’s accomplished by getting the index and then indexing back into players to get to the same player???
