代码签名错误每当我尝试在新的SceneKit应用程序中替换库存文件时 [英] Code Signing Error Whenever I try replacing stock files in new SceneKit application
问题描述
所以Xcode 8最近发布了，我仍然不确定究竟是什么导致了这个问题（可能只是因为它是Xcode的beta版本，或者我可能在某种程度上做错了什么）。
So Xcode 8 was recently released and I'm still unsure as to what exactly might be causing this problem (it might be just the fact that it's a beta version of Xcode or perhaps that I'm somehow doing something incorrectly).
手头的问题是我正在尝试创建一个新的SceneKit应用程序，而我正在使用.scn文件。
The problem at hand is that I'm trying to create a new SceneKit application and I'm currently messing around with the .scn files.
我在hero.scnassets中创建了一个.scn文件hero.scn，并在hero.scnassets文件夹中提供了一个名为heroTexture的.png文件。 png
I created a .scn file, "hero.scn" inside of a "hero.scnassets" and also provided a .png file inside of the hero.scnassets folder by the name of "heroTexture.png"
在GameViewController.swift文件中，该项目通常由Xcode 8.0 beta 1提供的代码编辑如下：
The code normally provided by Xcode 8.0 beta 1 for this project in the "GameViewController.swift" file was edited as follows:
原始代码：
...
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, y: 2, z: 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
结论问题：
为什么我要签名？我所做的只是替换文件时出错？
Why am I getting a signing error when all I've done is simply replaced files?
旁注：我知道如何让代码签名问题消失，但这涉及重新启动整个项目（我不介意）。然而，我遇到的问题是每当我更改文件时，都会收到此错误。
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.
PS：这是文件结构只是为了方便。
P.S: Here's a file structure just for ease.
推荐答案
通过三个简单步骤摆脱此构建错误：
Get rid of this build error in three easy steps:
1）删除DerivedData中与您的应用程序相关的最新文件夹（〜/ Library / Developer / Xcode / DerivedData）
1) delete the most current folder related to your app in DerivedData (~/Library/Developer/Xcode/DerivedData)
2）在终端，cd到当前项目目录
2) in the terminal, cd to the current project dir
3）运行
xattr -rc。
xattr -rc .
删除所有扩展属性（通常与以前在Photoshop中编辑过的图像文件有关）
to remove all extended attributes (usually related to image files previously edited in Photoshop)
重建你的应用程序！
