Swiftris displays poorly in iPhone6. How do I make it stretch?

I completed the free Swiftris tutorial. The game is sized for an iPhone5, but I'm on an iPhone 6, and there are large black blank areas on the right and bottom. How can I stretch/scale the view to use the whole screen?

Please see what I mean: https://www.dropbox.com/s/hyu709bcvifagji/%E5%86%99%E7%9C%9F%202014-10-03%2020%2037%2013.png?dl=0

Hi Jacques,

I encountered the same issue and after fiddling with the code found the addition of the following line of code (marked with '+') in the GameScene.swift file to do the trick:

override init(size: CGSize) {
        super.init(size: size)

        anchorPoint = CGPoint(x:0, y:1.0)

        let background = SKSpriteNode(imageNamed: "background")
        background.position = CGPoint(x:0, y:0)
        background.anchorPoint = CGPoint(x:0, y:1.0)
+       background.size = frame.size
        addChild(background)

In addition, you may wish to make the play area larger given all the available space on iPhone 6. If so, let me know and I can share my solution with you.

I think that the iPhone 6 and Plus are very new devices and scaling of elements would have to differ since this is a very big change in screen size and since their is now a 4 , 4.7 and 5.5 inch screens not everything would work on all . And you could try adjust the view controller by pressing the view controller then changing the size of the screen. And maybe scaling up the code .

Thank you for your reply Ben. I've tried changing the size of the view controller, and this and it doesn't fix the problem. Apple said that apps not designed for the iPhone 6 would be scaled (many of mine are).

HI Jacques !

Do you have size classes on ? If you do keep them on also with storyboards even though you don't use them you could enable the rectangle since i think that scales apps for all screen sizes .

When you say size classes, do you mean the Size property under "Simulated Metrics"?

Thanks for the suggestion. I've tried fooling with those settings and haven't had any luck.

I've done some research and i can see that this is very common for new users in Xcode because it didn't work for me until xcode 6 beta 7 so its very common all my problems were fixed when i upgraded to Yosemite weirdly but that is taking it far . Try re installing it and if you have any other mac computers try it on them

I'm using Yosemite 10.10 and Xcode 6.0.1.

Try Using App Zapper to completely erase xcode then install it again

I tried this, and it still won't display correctly. There must be a setting for this somewhere...

In the Xcode Preferences you can see if all documentation and file paths are correct maybe their is a problem their.
