Are you looking for a general purpose JSON interpreter / API ?
There are many of them around, and in fact I do have my own:
https://github.com/Balancingrock/VJson
With VJson I would write:
let json = VJson.parse(… your json object…)
and then access the metadata as:
let buyCount = (json | ”metadata” | ”buy_count”)?.intValue
or:
var buyCount: Int &= json | “metadata” | “buy_count”
To loop over the content of metadata:
for item in (json | “metadata”) ?? [ ] {
print (item.nameValue)
switch item.type {
case .object: …
case .number: …
case .string: …
etc...
}
}
Obviously I am plugging my own code here, but there are many others around, I
understand that SwiftyJSON is quite popular but I have not used that myself.

Rien
