ios - Parse - Swift : Concatenate Queries -

i'm creating ios app swift , parse.com. unfortunately, i've problem when build query.

what want : have class sport's players (with goals , passes). retrieve player goals , player passes. have 2 columns in parse class : goals , passes.

so, me, use

query_goals.limit = 1  query_goals.orderbydescending("goals")  query_passes.limit = 1 query_passes.orderbydescending("passes") 

and need concat 2 queries didn't find in swift ios documentation...

does have idea please ? :)

edit : want print best scorer , passer in collectionview cells :

override func queryforcollection() -> pfquery {     let query = pfquery(classname: "liste_joueurs")     query.limit = 1     query.orderbydescending("goals")      let query_passes = pfquery(classname: "liste_joueurs")     query_passes.limit = 1     query.orderbydescending("passes")      let final_query = query + query_passes //swift concat illustrate purpose      return final_query }   override func collectionview(collectionview: uicollectionview, cellforitematindexpath indexpath: nsindexpath, object: pfobject!) -> pfcollectionviewcell? {     let cell = collectionview.dequeuereusablecellwithreuseidentifier("statscell", forindexpath: indexpath) as! statsviewcell      // first cell best scorer      // second cell best passer     return cell  } 

in final_query,

let query = pfquery(classname : "sportsplayers") // im assuming classname change needed   // highest  scorer  query.orderbydescending("goals") query.limit = 1   // highest passes query.orderbydescending("passes") query.limit = 1
