I'm writing an app in Swift 2.0. The app works fine in every aspect, beside one. When I tilt the screen of both device and emulator the orientation change animation is missing. Instead of a smooth rotation I get a clunky orientation change. Portrait -> Landscape. Nothing in between. Giving the fact that the animation should be the default, I would like to know if anybody knows the possible solution to this problem. I searched everywhere and apparently nobody has this problem, instead people try to disable that animation!
After some tests and thanks to Zell.B, I moved the code from didFinishLaunchWithOptions to applicationDidBecomeActive and everything works fine.
