"loop all over its keys" can't "dictionary[key] = dic[key]"

JSON:

{
    "data": {
        "modules": [
            {
                "grids": [
                    {
                        “A”: "http://xxx”,
                    }
                ]
            },

                "grids": [
                    {
                        “B”: 1
                    }
                ]
           }
        ]
}
}

==> "grids.swift"

class Grid : NSObject, NSCoding, Mappable{

	var b : Int?

	class func newInstance(map: Map) -> Mappable?{
		return Grid()
	}
... ...

Can NOT export "A"。
so.

Hi,
Thanks for the suggested fix. I can apply it directly, but it is preferable if you create a PR so you can be credited for your efforts!
Thanks
