The first thing I'd try is to clean everything (menu Product / Clean) and the build it again. You might have already tried it.

You'll find (and you can watch during the build) the complete build output in the Log Navigator. That's the right most icon of the small icons just below the Run and Build buttons.

The build (and debug) log files are found in the directory /Users/you/Library/Developer/XCode/DerviedData/YourProject-abcdefg/Logs/Build (and ../Debug respectively).

I don't think there's any output for the installation of your app on the device.

Same problem here when building for device. Build failed, but my log all is green checkmarks. Cleaning/deleting build folder doesn't fix it. I read elsewhere that someone solved this problem by deleting and recreating the target, but I haven't completely figured out how to do that yet in XCode 4.

<hr>

My temporary solution has been to download and install XCode 3.2.6 w/iOS 4.3. I didn't realized that Apple had also released a version of XCode 3 that includes iOS 4.3, allowing you to postpone the upgrade to XCode 4. I filed a bug report with Apple about the Build Failed issue.

<hr>

udpate from Apple:

<blockquote>
 When we build this project - albeit on a post-Xcode 4.0 version - we see the following in the ProcessProductPackaging step in the build log:
 
 (null): error: CFBundleIdentifier 'com.yourcompany.Magic_Carpet' contains illegal character '_' invalid bundle identifier 'com.yourcompany.Magic_Carpet'
 
 The ProcessProductPackaging code got an overhaul fairly recently, so we suspect it just wasn't emitting errors properly in Xcode 4.0. Take a look at the transcript of your own build, and if so, then this will likely be fixed in a future release of Xcode (we cannot comment further until a fix has been released).
</blockquote>

I switched from an underscore to a dash and it fixed the problem.

On one of the local Cocoa Heads mailing lists I was encouraged to attempt a small default sample project - something I should have done in the beginning to make sure my provisioning and signing worked. It built and ran on my device without issue, so all signs point toward a problem with my code or the project.

I'll be throwing things from the existing project into the new sample project, and if it fails in a similar way I should be able to narrow the problem down to a smaller region of interest.

<hr>

I've added the main functionality of the app into a new project, and it's running fine. The only things I did differently this time was I did not set up a universal binary (iPhone only right now) and turned off all but portrait orientation. As far as I can tell everything else is the same, though if I decide to look into it further later I will diff the project files and see what else might be different.

So the solution for me was to start a new project a port all the functionality from the old project into the new project.

It could be that recreating the target, as Paul suggests in another answer, would fix it as well, but with such a simple project restarting from scratch was easy for me.

Is there a space in your Target's Product Name? 

I know that in earlier versions of Xcode this was no problem, but it seems that they broke something in Xcode 4 so it doesn't work any more (I suspect it's something to do with the DerivedData path nonsense). You can add a space to the name of your app as it appears on the Launchpad of your iDevice by setting the <code>CFBundleDisplayName</code> key in the <code>Info.plist</code> to something other than <code>${PRODUCT_NAME}</code>.

I had exactly the same problem when trying to compile an existing project in xcode 4, and very nearly went through the pain of recreating the project. 

However, in a last ditch attempt I replaced the info.plist file with a newly created one which included the additional tags for "document types", "url types", "Exported Type UTIs" and "Imported Type UTIs"

This seemed to work and was a surprisingly simple fix for my project.

<blockquote>
 The UTI Character Set A uniform type identifier is a Unicode string
 that usually contains characters in the ASCII character set. However,
 only a subset of the ASCII characters are permitted. You may use the
 Roman alphabet in upper and lower case (A–Z, a–z), the digits 0
 through 9, the dot (“.”), and the hyphen (“-”). This restriction is
 based on DNS name restrictions, set forth in RFC 1035.
 
 Uniform type identifiers may also contain any of the Unicode
 characters greater than U+007F.
 
 Important: Any illegal character appearing in a UTI string—for
 example, underscore ("_"), colon (":"), or space (" ")—will cause the
 string to be rejected as an invalid UTI. At the API layer, no error is
 generated for invalid UTIs.

blocks|key|275714|text|我刚刚遇到了类似的问题。在任何地方都找不到错误。删除了我的所有配置配置文件并添加了新配置文件。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|275715|然后我尝试在我的设备上构建另一个测试应用程序，我得到了这个错误消息：|275716|代码签名错误:证书标识'iPhone+Developer:+xxxxxx‘在密钥链中出现多次。codesign工具只需要一个。|275717|因此，我进入Keychain，找到两个名称相同的过期证书，并将其删除，这就完成了任务。|275718|非常随机，但如果您尝试像我一样为设备构建另一个应用程序，您可能会很幸运地得到一条错误消息，就像我一样，以帮助诊断问题。|275719|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|N|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|O|8|@]|9|@]|A|$]]|$1|H|3|I|5|6|7|P|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|K|$]]

I just had a similar problem. Could not find an error anywhere. Deleted all my provisioning profiles and added new ones.

Then I tried building another test app to my device and I got this error message:

Code Sign error: Certificate identity 'iPhone Developer: xxxxxx' appears more than once in the keychain. The codesign tool requires there only be one.

So I went into Keychain, found a couple of expired certificates with the same name, and deleted them, and that did the trick.

Pretty random, but perhaps if you try building another app to the device like i did, you might be lucky enough to get an error message, as i did, to help diagnose the problem.

blocks|key|275727|text|对我来说，构建失败了，没有在问题导航器中显示任何错误。但是，在Log+Navigator中，在构建会话中，我可以看到错误。在我的例子中，错误是一个未声明的常量。我导入了所需的头文件，问题已解决。我不确定为什么问题导航器中没有显示此错误。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|275728|我试图通过故意更改另一个变量的名称来重现这种行为。这一次，错误显示在问题导航器中。所以，我仍然不确定为什么之前的错误不会出现在问题导航器中。|275729|希望这能有所帮助。|275730|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

For me, the build failed without displaying any errors in the Issue Navigator. However, in the Log Navigator, in that build session, I could see the error. In my case, the error was an undeclared constant. I imported the required header file and the problem was resolved. I am not sure, why this error did not show up in the Issue Navigator.

I tried to reproduce this behavior by deliberately changing the name of another variable. This time, the error was displayed in Issue Navigator. So, I am still unsure about why wouldn't the earlier error show up in the Issue Navigator.

Hope this helps.

After going though all these answers, I had the exact same issue, but something different solved it for me.

The Problem:

Build failed without issues after refactoring. (Renamed a class using Edit -> Refactor -> Rename).

The Dumbest Solution Ever:

Go refactor (rename) something else (-_-"). After doing that, the error was that Xcode failed to rename all appropriate files, and didn't show errors. Then, after another refactor, the errors from the previous refactor appeared.

When I attach my device (iPhone 3GS running iOS 4.3) and target the iPhone, the result is "Build failed" with "No issues".

Looking at the build results window, everything is green, has a checkmark, including the Build failed notice.

Expanding the transcripts show no errors.

I cannot exclude the possibility of a signing or provisioning error, but it gave me those errors, I ironed them out, and now it's not giving me any errors or issues, just "Build failed; No issues"

<ul>
<li>In what ways can the build fail with no issues?</li>
<li>Is there a way I can watch the build output to see if I can find the reason it's failing with no issues?</li>
<li>Is there build output produced beyond the issues list?</li>
<li>I don't see on the build window where it attempts to load the app onto my device - is this output elsewhere?</li>
