Cannot select json array from rest api using Alamofire - json

Question

I am new to swift and I am trying to get a link from a json file using Alamofire. I have been searching google for days now and have not found any useful solutions. I am not that good with json arrays.
I need the link from (_links.https://api.w.org/featuredmedia.href) this is my code:
guard let ide = self.json[0]["_links"]["https:\/\/api.w.org\/featuredmedia"]["href"].string else{
print("Request failed with error")
return
}
print(ide)
Alamofire.request(.GET, "http://tricitychurchofchrist.com/wp-json/wp/v2/ctc_sermon/5640").responseJSON { response in
guard let _ = response.result.value else{
print("Request failed with error")
return
}
}
And here is the json:

I am using WP REST API fro the json from the wordpress site.

Answer 1

the data type you returnd is object type,you should change it to JSON object,you can use SwiftJSON open source on github,and code like this:
Alamofire.request(.GET, url, parameters: ["foo": "bar"])
.response { request, response, data, error in
let jsonval = JSON(data:data!)
let jsonDic:NSDictionary = jsonval.object as! NSDictionary
}
jsonDic is now a NSDictionary type,change NSDictionary to NSArray, and you can use it directly,hope help
