ios - Calling a function more than once swift, returning the same data -

so in swift call in function in ui picker

 func pickerview(pickerview: uipickerview, didselectrow row: int, incomponent component: int) {          switch row{         case 0:             //switch out returning actual selected item picker not using picker array             let poke = ("\(mooarray[0])")             getpokemon(poke);         case 1:             let poke = ("\(mooarray[1])")             getpokemon(poke);         case 2:             let poke = ("\(mooarray[2])")             getpokemon(poke);         default:             println("stopping")         }          //self.view.backgroundcolor = newbackcolor;      } 

as can see calls getpokemon, passes through pokemon string, getpokemon function below

func getpokemon(poke: string)     {         println("\(poke)");         //var pokemon = "charizard"         var url = "http://pokeapi.co/api/v1/pokemon/" + poke          alamofire.request(.get, url)             .responsejson { (req, res, json, error) in                 if(error != nil) {                     nslog("error: \(error)")                     println(req)                     println(res)                 }                 else {                     //nslog("success: \(url)")                     let json = json(json!)                     //println("\(json)")                     if let ability = json["abilities"][0]["name"].string                     {                         //println("the title is: \(ability)")                     }                     if let evolevels = json["evolutions"][0]["level"].number                     {                         //println("\(evolevels)")                     }                     if let attack = json["attack"].number                     {                         //println("\(attack)")                         self.pokemon.append("\(attack)");                     } else                     {                         println(json["attack"].error)                     }                     if let name = json["name"].string                     {                         //println("\(name)")                         self.pokemon.append("\(name)");                      }                     println("\(self.pokemon[0])")                     println("\(self.pokemon[1])")                  }         }      } 

this uses alamo fire , swifty json. takes string, appends url api calls , returns data printing console.

this working fine when select row 1st time, makes call , returns right data api.

however if select row returns same data? reason why call not refresh new string passed though?

just possibility here, happens if change print from:

println("\(self.pokemon[0])") println("\(self.pokemon[1])") 

to:

println("\(self.pokemon.last)") 

i think you're getting new data not logging because new entries inserted end of array, , you're logging first element.
