nsautoreleasepool - How to use autopoolrelease in swift -


the use of autoreleasepool{} in swift follows. 

autoreleasepool {     // usage here }

but not know how use in public.

example

class viewcontroller: uiviewcontroller {     autoreleasepool {         var results: results<item>!     }      override func viewdidload() {         super.viewdidload()         .....       } }

if public, error occurs. autoreleasepool{} need in func only?
