SpriteKit Xcode 6包含iOS 7.1.1设备上的示例项目崩溃（EXC_BAD_ACCESS）

我是iOS开发新手。 我试图运行包含在Xcode 6中的示例SpriteKit。它在目标8.0的仿真器上运行，目标设置为7.1。

当我尝试在我的设备（iPhone 5，iOS 7.1.1）上运行它时，它在渲染精灵时会出现EXC_BAD_ACCESS（参见下面的堆栈跟踪）。 我没有以任何方式更改Xcode 6中提供的示例中的代码。 我尝试了其他开源SpriteKit项目，并遇到相同types的错误。

如果我注释掉代码，以便只在用户触摸时调用self.addChild(sprite) ，它将运行良好，直到触摸屏幕。

我认为这可能是Xcode6的一个错误，但是使用谷歌search，我发现没有其他人有类似的问题。 我是否设置了自己的开发环境或以某种方式构build了项目？ （注：xcassets似乎很好）
