试图在ViewController中显示字典值

Question

我可以正常返回字典值，但无法弄清楚如何在视图控制器中显示它们。如您所见，由于每个地方的子键都不同，因此返回的键/值有些不同。 我将整个子例程放在此处以提高清晰度。打印（待办事项）打印出来

> Got data
The todo is: ["mining": {
    1532638123799234661 =     {
        command = mining;
        siteid = "Platform Mining";
        ts = 1532638118480;
        user1 = 73276;
        value = 1;
    };
    153264129781238193 =     {

如您所见，每个连续键都是一个不同的数字。因此，首先我要如何在每次输入不同的数字或键名时引用该键？

现在，下一位，forKey，value会简单地打印出整个字典。

for (forKey,value) in todo {
    print("\(forKey) : \(value)")
}

这是30件物品的退货。

Got data
mining : {
1532583713635640435 =     {
    command = mining;
    siteid = "Platform Mining";
    ts = 1532583706411;
    user1 = 12345;
    value = 1;
};
1532585218556932431 =     {
    command = mining;
    siteid = "Platform Mining";
    ts = 1532585212726;
    user1 = 12345;
    value = 1;
};

从此处编辑：

可以看出，它几乎可以正常工作，但是现在我知道一个主要问题实际上是访问字典元素，并找到这些元素的路径，因为第一个键始终是一个不同的名称。即；

1532638123799234661 =
153264129781238193 =

那么，每次密钥名称不同时，如何告诉它密钥路径？我认为这是我最大的问题。

> ["mining": {
    1532638123799234661 =     {
        command = mining;
        siteid = "Platform Mining";
        ts = 1532638118480;
        user1 = 73276;
        value = 1;
    };
    153264129781238193 =     {
        command = mining;
        siteid = "Platform Mining";
        ts = 1532641293697;
        user1 = 73276;
        value = 1;
    };
