SwiftyJSON map for array

Question

let json = JSON(response.result.value!)

let things = json.array.map { jsonThing in          
   Thing()                    
}!

json.arrayreturns an array of one hundred JSONs. After the call, mapI get one Thing.

Why don't I have a new Things array ?

Answer 1

SwiftyJSON has two types of getters: optional and optional.

Optional getters have the syntax of the name "... Value".

Additionally:

json.array

non-optional:

json.arrayValue

: , . , if let ( ) : , ..

Answer 2

json.array [JSON]?, [JSON]

, .map Optional<[JSON]>, Array<JSON>, .

:

json.array?.map ...
