When calling PHP service from Swift for iOS 9, results don't display -

i'm new swift , trying set ios app. @ start of app i'm dropping pin on map , sending location php web service. after next 10 iterations through map movement, pin dropped , location gets sent service. looking @ database getting service , getting loaded tables. but, first time calling service time response data can retrieved.

here's view controller:
