无法将更新的字典数组存储到userDefaults

Question

编辑，回答：

相当简单，本来应该发现这个：NSUserDefaults似乎仍然需要Cocoa属性列表对象才能工作，所以问题是在字典中使用常规的Swift Ints。它们仍然需要是适当的对象（显然）并包裹在NSNumber中。

标题所说的几乎是什么。 我有一个由三个字典组成的数组用于savedGamesData ...

savedGames[savedGameSlot] = currentSavedGame
userDefaults.setObject(savedGames, forKey: "savedGames")
println("Saving savedGames: \(savedGames)")
userDefaults.synchronize()
println(userDefaults.dictionaryRepresentation())

savedGames是字典数组，currentSavedGame是更新的字典，userDefaults是.standardUserDefaults第一个println向我显示数据已按我的预期更改。请注意第二个字典：

Saving savedGames: [
[score: 0, greatestTournamentReached: 1, goats: 0, match: 1, cash: 25, lastTournamentPlayed: 1, tournament: 1, gamesPlayed: 6, batSize: 1, greatestMatchReached: 2, bats: 2], 
[score: 0, greatestTournamentReached: 1, goats: 0, match: 2, cash: 11, lastTournamentPlayed: 1, tournament: 1, gamesPlayed: 2, batSize: 1, greatestMatchReached: 3, bats: 3], 
[score: 0, greatestTournamentReached: 1, goats: 0, match: 1, cash: 0, lastTournamentPlayed: 1, tournament: 1, gamesPlayed: 0, batSize: 1, greatestMatchReached: 1, bats: 3]]

但是，当我在同步后打印userDefaults 时，尚未存储更改：

savedGames: (
    {
    batSize = 1;
    bats = 2;
    cash = 25;
    gamesPlayed = 6;
    goats = 0;
    greatestMatchReached = 2;
    greatestTournamentReached = 1;
    lastTournamentPlayed = 1;
    match = 1;
    score = 0;
    tournament = 1;
},
    { // This is the one that should have been changed
    batSize = 1;
    bats = 3;
    cash = 1;
    gamesPlayed = 1;
    goats = 0;
    greatestMatchReached = 1;
    greatestTournamentReached = 1;
    lastTournamentPlayed = 1;
    match = 1;
    score = 0;
    tournament = 1;
},
    {
    batSize = 1;
    bats = 3;
    cash = 0;
    gamesPlayed = 0;
    goats = 0;
    greatestMatchReached = 1;
    greatestTournamentReached = 1;
    lastTournamentPlayed = 1;
    match = 1;
    score = 0;
    tournament = 1;
}
