如何清空缓存并清理所有目标 Xcode 4 及更高版本

How to Empty Caches and Clean All Targets Xcode 4 and later

提问by Tieme

Jonathan suggest here: Xcode Includes .xib files that have been deleted!that cleaning all targets and empty the caches will fix the problem with Xcode including deleted .xib files but I cannot find a way to empty the cache in Xcode 4.

乔纳森在这里建议：Xcode 包括已删除的 .xib 文件！清除所有目标并清空缓存将解决 Xcode 的问题，包括已删除的 .xib 文件，但我找不到在 Xcode 4 中清空缓存的方法。

How to do that in Xcode 4?

如何在 Xcode 4 中做到这一点？

Command-Option-Shift-K to clean out the build folder. Even better, quit Xcode and clean out ~/Library/Developer/Xcode/DerivedDatamanually. Remove allits contents because there's a bug where Xcode will run an old version of your project that's in there somewhere. (Xcode 4.2 will show you the Derived Data folder: choose Window > Organizer and switch to the Projects tab. Click the right-arrow to the right of the Derived Data folder name.)

Command-Option-Shift-K 清除构建文件夹。更好的是，退出 Xcode 并手动清理~/Library/Developer/Xcode/DerivedData。删除其所有内容，因为存在一个错误，即 Xcode 将运行位于某处的旧版本项目。（Xcode 4.2 将显示派生数据文件夹：选择窗口 > 管理器并切换到项目选项卡。单击派生数据文件夹名称右侧的右箭头。）

In the simulator, choose iOS Simulator > Reset Content and Settings.

在模拟器中，选择 iOS Simulator > Reset Content and Settings。

Finally, for completeness, you can delete the contents of /var/folders; some caching happens there too.

最后，为了完整起见，您可以删除/var/folders的内容；一些缓存也发生在那里。

WARNING: Deleting /var/folderscan cause issues, and you may need to repair or reinstall your operating system after doing so.

警告：删除/var/folders可能会导致问题，执行此操作后您可能需要修复或重新安装操作系统。

EDIT: I have just learned that if you are afraid to grapple with /var/folders/you can use the following command in the Terminal to delete in a more targeted way:

编辑：我刚刚了解到，如果您害怕处理/var/folders/，您可以在终端中使用以下命令以更有针对性的方式进行删除：

rm -rf "$(getconf DARWIN_USER_CACHE_DIR)/org.llvm.clang/ModuleCache"

EDIT: For certain Swift-related problems I have found it useful to delete ~/Library/Caches/com.apple.dt.Xcode. You lose a lot when you do this, like your spare copies of the downloaded documentation doc sets, but it can be worth it.

编辑：对于某些与 Swift 相关的问题，我发现删除~/Library/Caches/com.apple.dt.Xcode很有用。当你这样做时，你会损失很多，比如你下载的文档文档集的备用副本，但它是值得的。

Command-Option-Shift-K should do it. Alternatively, go to product menu, press the option key, now the option "Clean" will change to "Clean Build Folder ..." select that option.

Command-Option-Shift-K 应该这样做。或者，转到产品菜单，按选项键，现在选项“清理”将更改为“清理构建文件夹...”选择该选项。

I found another way in addition to command+option+shift+K. In XCode 4.2 there is an organizer that can be opened from top-right icon. You can clean all archives and saved project options from there. This helped my situation (I was seeing old removed files in the mainBundle).

除了command+option+shift+K，我找到了另一种方式。在 XCode 4.2 中有一个可以从右上角的图标打开的管理器。您可以从那里清理所有档案和保存的项目选项。这对我的情况有所帮助（我在 mainBundle 中看到已删除的旧文件）。

In addition to doing the following, you may experience this issue if your app's Storyboard's files are localized. First, do each of these:

除了执行以下操作外，如果您的应用程序的 Storyboard 文件已本地化，您可能会遇到此问题。首先，执行以下各项：

• Clean Build
• Reset Simulator
• Restart Xcode
• Delete your DerivedDatafolder in ~/Library/Developer/Xcode/DerivedData
• Restart Computer

• 清洁构建
• 重置模拟器
• 重启Xcode
• 删除~/Library/Developer/Xcode/DerivedData 中的DerivedData文件夹
• 重启电脑

What finally worked for me was re-generating the storyboard localization files and deleting the English localization (which was unneeded because the Base Locale is English). To reload your Storyboard strings, see this answer on StackOverflow.

最终对我有用的是重新生成情节提要本地化文件并删除英语本地化（这是不需要的，因为基本语言环境是英语）。要重新加载 Storyboard 字符串，请参阅 StackOverflow 上的此答案。

I had noticed that the non-text parts of my Storyboard were being updated, but not the localized text. If you have a localization in your app, I would recommend checking to make sure your localizations are updated (even if they're .stringsfiles).

我注意到我的 Storyboard 的非文本部分正在更新，而不是本地化的文本。如果您的应用中有本地化，我建议您检查以确保您的本地化已更新（即使它们是.strings文件）。

I have been pulling out hair from my head because I thought that I had the same problem. When building the app I didn't get the same result on my iPhone as on the simulator.

我一直在拔头发，因为我认为我有同样的问题。在构建应用程序时，我在 iPhone 上没有得到与在模拟器上相同的结果。

The problem was that I had somehow made a localized version of the MainStoryboard.storyboard file. So when I ran the app on my phone it showed the danish version... and the simulator showed the english version.

问题是我以某种方式制作了 MainStoryboard.storyboard 文件的本地化版本。因此，当我在手机上运行该应用程序时，它显示了丹麦语版本……而模拟器显示了英语版本。

Yeah I'm new! :)

是的，我是新来的！:)

To delete all derived data and the module cache in /var/foldersuse this little ruby script.

要删除所有派生数据和/var/folders使用这个小 ruby​​ 脚本的模块缓存。

derivedDataFolder = Dir.glob(Dir.home + "/Library/Developer/Xcode/DerivedData/*")
moduleCache = Dir.glob("/var/folders/**/com.apple.DeveloperTools*")
FileUtils.rm_rf derivedDataFolder + moduleCache

This just solved a fatal error: malformed or corrupted AST file: 'Unable to load module "/var/folders/error for me.

这只是fatal error: malformed or corrupted AST file: 'Unable to load module "/var/folders/为我解决了一个错误。

I had some problems with Xcode 5.1 crashing on me, when I opened the doc window.

当我打开文档窗口时，我遇到了一些 Xcode 5.1 崩溃的问题。

I am not sure of the cause of it, because I was also updating docsets, while I opened the window.

我不确定它的原因，因为我也在更新文档集，而我打开窗口。

Well, in Xcode 5 the modules directory now resides within the derived data folder, which I for obvious reasons didn't delete. I deleted the contents of ~/Library/Developer/Xcode/DerivedData/ModuleCacheand the ~/Library/Preferences/com.apple.Xcode.plistand everything then seems to work, after I restarted Xcode.

好吧，在 Xcode 5 中，模块目录现在位于派生数据文件夹中，我出于显而易见的原因没有删除它。我删除了~/Library/Developer/Xcode/DerivedData/ModuleCache和~/Library/Preferences/com.apple.Xcode.plist 的内容，然后一切似乎都在我重新启动 Xcode 后工作。

When using a "Data Model" , there are options in the inspector to generare classes, for me this was the case as there was already a class with the existing name.

使用“数据模型”时，检查器中有一些选项可以生成类，对我来说就是这种情况，因为已经有一个具有现有名称的类。

Codegen: solved it for me.

Codegen：帮我解决了。

Here's my shell script solution, which deletes derived data and cleans a project's cached assets, for Xcode 4, 5 and 6.

这是我的shell 脚本解决方案，它删除派生数据并清除项目的缓存资产，适用于 Xcode 4、5 和 6。

Sometimes, simply calling rm -rf on the Derived Data directory leaves a lingering file or two, but my script loops until all files are deleted.

有时，只需在派生数据目录上调用 rm -rf 会留下一两个文件，但我的脚本会循环播放，直到所有文件都被删除。
