问题
Since upgrading to iOS 9 I have this strange issue with image atlases in my SpriteKit game. In my game I have a StartScene, a MenuScene and a GameScene.
In all 3 scenes I am using atlases for my enemies so I can animate them. All worked fine on all devices but since upgrading iOS 9 it causes me issues on iPads.
On my iPad when I launch the game the enemies in StartScene are about 3 times as big as they should be. Whats strange is that when I move to menuScene or gameScene the enemies are normal size. When I tell my game to launch straight into MenuScene I have the same problem, enemies are way to big until I change to another scene. This happened as soon as I run my game on iOS 9 and even after I upgraded to swift 2 and Xcode 7 I am still having this issue.
Anyone seeing this too, I have no clue what could cause this and how to fix it. Is this just a terrible iOS 9 bug? Thanks for any help.

I saw there's a new option in the Xcode assets. If you click on the plus sign and select Sprite Kit Asset, you may fix the problem.

This was purely an iOS 9 bug and I believe was fixed. The initial code for my game was not doing any SKScene scaling, I did it all manually for every device, which was a terrible idea. Since asking this question I have change the way my scenes are scaled (AspectFill) so I am not 100% sure if this bug is still occurring.
