I'd probably do something like this:

for (var key in [userDict allKeys])
{
    console.log(key, userDict[key]);
}

But your dictionary looks wrong; this:

@{
    @"name":         @"Jack",
    @"secondName":   @"Buck",
    @"name":         @"Jacob",
    @"secondName":   @"Smith"
};

Will overwrite the name and secondName indices and result in:

@{
    @"name":         @"Jacob",
    @"secondName":   @"Smith"
};

You probably wanted a CPArray of CPDictionary:

var users = [
    @{
        @"name":         @"Jacob",
        @"secondName":   @"Smith"
    },
    @{
        @"name":         @"Jacob",
        @"secondName":   @"Smith"
    }
];

Then if you loop over users; you get one user dictionary for each step in the loop, and you can address its ' indices (properties). Since both CPArray and CPDictionary are tollfree-bridged to their native javascript counterparts, you can still do this:

for (var ix = 0; ix < users.length; ix ++)
{
   var user = users[ix];
   console.log(user.name, user.secondName);
}

Hope this helps.
