swift 3 parse json array as key value

Question

i have a json, which i parse as a dictionary. Now most is simply a key value pair like "title":{"this is the title"}. The one thing bugging me is a key value pair that has an array for value.

"hashTags":[{"name":"pizza"},{"name":"salami"},{"name":"diet"}]

i do not want to use SwiftyJSON, since this is the only part i am unable to solve. What i need is to convert this value into an Array, which i can iterate. I had some approaches, they failed because they added new lines or stopped displaying äöü symbols.

Thank you in advance!

hashTags is an array of dictionaries with String keys and values, cast it to [[String:String]]

Iterate thru the array with a for loop and print all values for key name

if let hashTags = json["hashTags"] as? [[String:String]] {
   for tag in hashTags {
       print(tag["name"])
   }
}

It's assumed that json is the parent object which contains the key hashTags.

All you need is using codable.

You can use Codable to parse Json to your desired model easily. you can check following document for more detail:
