I constantly had this since upgrading from Xcode 4.6 to Xcode 5 with iOS projects when using command line build (xcodebuild).

What worked for me is to use this as command line build command:

<pre><code>xcodebuild -project path/to/my.xcodeproj -configuration Debug clean build
</code></pre>

Before this, I've tried:

<ul>
<li>Clean the project in Xcode GUI.</li>
<li>Delete the offending pch file.</li>
<li>Delete the offending pch file's parent folder.</li>
<li>Delete the DerivedData project folder.</li>
</ul>

None of the above worked for me under Xcode 5.0.2, Mavericks, iOS7.

Note that the problem didn't happen to me when using Xcode GUI.

blocks|key|196413|text|我逐个尝试了这些方法，但未能构建和运行我的项目。因此，我将预编译前缀头文件更改为NO，如@Abhilash所述，然后我重置模拟器，删除派生数据，删除相应的.pcm文件(在我的示例中是UIKit框架中的UIImage.h，因此删除了UIKit.pcm).Then我清理了项目，然后才能够成功构建它。在早期版本的Xcode中，这些文件基本上是锁定的，不允许编辑。但现在不是这样了。希望这对那些面临同样情况的人有所帮助。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|196414|entityMap^0|T|8|14|2|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

I tried these one by one but failed to build and run my project. So I changed Precompile Prefix Header to NO as mentioned by @Abhilash Gopal, then I reset the simulator,deleted the derived data, removed the corresponding .pcm file(In my case it was the UIImage.h from UIKit framework, so removed the UIKit.pcm).Then I cleaned the project and only then I was able to build it successfully. In earlier versions of Xcode these files were locked basically and were not allowed to edit. But its not the case now. Hope this helps someone who face the same situation.

For me, this problem is only occurring in Xcode 6 beta version, So I switch back to Xcode 5, and now problem is solved.

So, if you have both versions of Xcode and have issue only in Xcode 6 beta, then switch to Xcode 5 and clean the project, problem will be solved.

The only solution there worked for me was running the following command:

<pre><code>sudo rm -R /var/folders/
</code></pre>

But that gave me a lot of troubles in OS X.

I thought because /var/folders/ is for temporary files it should be okay to just empty anything in it.
But I was wrong see the following post: <a href="https://apple.stackexchange.com/questions/121317/com-apple-iconservices-is-causing-high-cpu-usage-and-finder-problems-in-maverick">link</a>

And the problem you described occurred every-time I tried to build my Xcode project - I'm building it from the CLI though Jenkins.

Which means I couldn't run the rm command every-time. So I found some inspirations and wrote the following ruby script which solved my problem:

<pre><code>#!/usr/bin/env ruby

require 'fileutils'

cache = Dir.glob("/var/folders/**/com.apple.DeveloperTools*")
FileUtils.rm_rf(cache)
</code></pre>

I hope it would be helpful to someone.

Deleting <code>project.xcworkspace</code> did a trick for me. 

<code>project.xcworkspace</code> is a directory which describes schema of current Xcode workspace state. Each time Xcode is launched it will regenerate <code>project.xcworkspace</code> if not exist already.

<ul>
<li>Right click on your project file <code>yourProject.xcodeproj</code> </li>
<li>From drop-down menu choose <code>Show Package Content</code></li>
