How do I access the name of the first resident? Here is the Json file. What comes after the following?
val bigwig = (json \ "residents")(1).....
import play.api.libs.json._
val json: JsValue = Json.parse("""
{
"name" : "Watership Down",
"location" : {
"lat" : 51.235685,
"long" : -1.309197
},
"residents" : [ {
"name" : "Fiver",
"age" : 4,
"role" : null
}, {
"name" : "Bigwig",
"age" : 6,
"role" : "Owsla"
} ]
}
""")

You use the JSValue class to convert basic values, such as numbers and strings, between JavaScript and Objective-C or Swift representations to pass data between native code and JavaScript code.
The Play JSON API provides implicit Writes for most basic types, such as Int , Double , String , and Boolean . It also supports Writes for collections of any type T that a Writes[T] exists. import play. json.
Quick and dirty (with no validation):
((jsonObject \ "residents").as[Seq[JsObject]].head \ "name").as[String]
