Xcode不会编译为模拟器 [英] Xcode Won't Compile To Simulator

问题描述

我刚刚通过App Store更新了Xcode 4.5，从我以前的版本，我从我的苹果开发者帐户。从更新我无法编译任何应用程序到模拟器。我可以编译到设备上，例如。我的iPhone。

I've just updated Xcode 4.5 via the App Store, from my previous version which I got from my Apple Developer Account. Since the update I can't compile any apps into the Simulator. I can compile onto a device, e.g. my iPhone.

我收到的错误是

    fatal error: file 
    '/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/
Developer/SDKs/iPhoneSimulator6.0.sdk/usr/include/Availability.h'
         has been modified since the precompiled header was built

1 error generated.

推荐答案

进入〜/ Library / Developer / Xcode / DerivedData / {project name + gobly-gook} 并删除包含您的项目名称的文件夹。

go in ~/Library/Developer/Xcode/DerivedData/{project name + gobly-gook} and delete folder with your project name.

> EDIT建议之后

注意：

1.通过以下命令取消隐藏库文件夹以取消隐藏〜/ Library文件夹

1.Unhide Library folder by following command to unhide ~/Library folder

chflags nohidden ~/Library

现在可以看到Library文件夹为/ Users //库

2.打开GO菜单并按Alt键和库将作为新的菜单项显示。

选择打开库文件夹

3.您可以访问〜/ Library文件夹终端。

Now you can see Library folder as /Users//Library

2. Open GO menu of finder and press Alt key and Library will be visible as new menu item.
Select that to open Library folder

3. You can access ~/Library folder by Terminal.
