目前的问题是我正在尝试创建一个新的SceneKit应用程序，而我目前正在使用.scn文件。

我在“hero.scnassets”里面创建了一个.scn文件“hero.scn”，并且在“heroTexture.png”的名称中还提供了一个.png文件，在hero.scnassets文件夹里面

通常在“GameViewController.swift”文件中为此项目的Xcode 8.0 beta 1提供的代码编辑如下：

原始码：

...
let scene = SCNScene(named: "art.scnassets/ship.scn")!
...
let ship = scene.rootNode.childNode(withName: "ship",recursively: true)!
ship.run(SCNAction.repeatForever(SCNAction.rotateBy(x: 0,y: 2,z: 0,duration: 1)))

编辑代码：

...
let scene = SCNScene(named: "hero.scnassets/hero.scn")!
...
let hero = scene.rootNode.childNode(withName: "hero",recursively: true)!
hero.run(SCNAction.repeatForever(SCNAction.rotateBy(x: 0,duration: 1)))

收到错误：

.../Xapp.app: resource fork,finder information,or similar detritus not allowed
Command /usr/bin/codesign Failed with exit code 1

问题结论：

Why am I getting a signing error when all I’ve done is simply replaced files?

Sidenote: I know how to get the code signing issue to go away but that involves restarting the entire project (which I don’t mind). The problem I face however is whenever I change the files,I get this error.

P.S：这是一个文件结构，只是为了easy.
