sprite kit - Swift and Spritekit won't run on device running iOS 7.1

Question

I'm getting a really weird warning when I try to run my Swift project on my device, using Xcode 6.

The device is running iOS 7.1, and my mac is running Mavericks.

I have written a little game in Swift and SpriteKit, and it works in Simulator, but when I try to run it on my device, I get a warning, and my device only shows a black background.

I get the same result when trying to run a fresh SpriteKit project. But if I run a fresh Single Page Application using Swift, it runs normally.

This is the warning I get:

Any suggestions?

I also got this crash and, comparing to the 7.1.1 SDK SpriteKit game template, it appears to be related to loading the scene from an .sks file.

I changed it to use a different initializer like this:

let scene = GameScene(size: skView.bounds.size)

After that, the template project is not crashing anymore on my iPad mini with iOS 7.1.1. However, the plane sprites don't get rendered. You can see the node count (on the bottom right corner) go up with each tap, but the sprites aren't visible. The "Hello, World!" label shows fine, though...
