ios - Swift - Preload other tab views from App Delegate -


so trying preload tab views app delegate save time on loading once user switching between tabs.

i have tried running in view controller file uitabbarcontroller (specifically in viewdidload) have had no luck. missing something?

 let = self.view  if let viewcontrollers = self.viewcontrollers {       viewcontroller in viewcontrollers {            let = viewcontroller.view       }  } 

try instantiating view controller...

first set storyboard id of view controller

then:

let storyboard = uistoryboard(name: "main", bundle: nil) let vc = storyboard.instantiateviewcontrollerwithidentifier("someviewcontroller") 

note: possible if put code in app delegate, view controller uninstantiated. if case, try putting code in first view controller.
