从plist swift读一本字典

Question

我正在尝试从我的plist中读取一些词典，但不幸的是，我的代码在plist中看不到任何词典。这是我的plist：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>BestScore</key>
    <integer>0</integer>
    <key>Coins</key>
    <integer>0</integer>
    <key>UserName</key>
    <string>Anonim</string>
    <key>Store</key>
    <dict>
        <key>Shoes</key>
        <dict/>
        <key>Hats</key>
    <dict>
        <key>hatMagic2</key>
        <dict>
            <key>Price</key>
            <integer>300</integer>
            <key>name_EN</key>
            <string> MAGIC HAT 2</string>
            <key>plusHealth</key>
            <integer>150</integer>
        </dict>
        <key>hatMagic1</key>
        <dict>
            <key>Price</key>
            <integer>200</integer>
            <key>name_EN</key>
            <string>MAGIC HAT 1</string>
            <key>plusHealth</key>
            <integer>100</integer>
        </dict>
        <key>hatMagic</key>
        <dict>
            <key>Price</key>
            <integer>100</integer>
            <key>name_EN</key>
            <string>MAGIC HAT</string>
            <key>plusHealth</key>
            <integer>50</integer>
        </dict>
    </dict>
</dict>
</dict>
</plist>

我的代码看起来像那样：

var paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as String
var path = paths.stringByAppendingPathComponent("UserInfo.plist")  
var data = NSMutableDictionary(contentsOfFile: path)
println(data)

但是swift没有看到任何字典，输出：

{
BestScore = "789.5";
Coins = 289;
UserName = Anonim;
}

那么，我如何从plist中读取这些词典？
