I had the same problem. For me the reason was that I was using the same bridging-header for both my App and my Today Extension. My Today Extension does not include Parse, but because it was defined in the bridging-header it was trying to look for it. I created a new bridging-header for my Today Extension and the error dissapeared.

<li>The "Objective-C Bridging Header" setting (aka <code>SWIFT_OBJC_BRIDGING_HEADER</code>) must be set at the Target level, and NOT the Project level. Be sure to delete the setting value at the Project level.</li>

When we added the second swift test case, after a clean (or on a team mate's machine), we saw this error when building the unit test target.

It was fixed by adding a dummy Obj-C class to the unit test target.

I had to add my <code>lib</code> directory in User Header Search Paths:

In my case the <code>lib</code> directory contains the <code>.a</code>-library file and some header files. These are included in the bridging header file. However, the swift compiler wouldn't find them. Only when I added <code>${PROJECT_DIR}/lib</code> to the User Header Search Path it built the test target.

Well its little strange but I guess you have to add a resource to your "Copy Bundle Resources" phase of your test target to make it load all headers from your main app target. In my case, I added <code>main.storyboard</code> and it took care of the error.

Xcode 8. Swift Project - importing Objective C. 

Things to know:

<ol>
<li>Bridging header file MUST be saved within the project's folder. (i.e. not saved at the same level that .xcodeproj is saved, but instead one level further down into the folders where all your swift and objective c files are saved). It can still find the file at the top level, but it will not correctly link and be able to import Objective C files into the bridging header file</li>
<li>Bridging header file can be named anything, as long as it's a .h header file</li>
<li>Be sure the path in Build Settings > Swift Compiler - General > Objective C Bridging Header is correctly pointing to you bridging header file that you made</li>
<li>IMPORTANT: if you're still getting "not found", try to first empty your bridging header file and erase any imports you currently have written there. Be sure that the bridging header file can be found first, then start to add objective c imports to that file. For some reason, it will kick back the same "not found" error even if it is found but it doesn't like the import your trying for some reason</li>
<li>You should not #import "MyBridgingHeaderFile.h" in any of your objective C files. This will also cause a "file not found" error</li>
</ol>

I had similar problem and only one solution worked out for me. I tried everything suggested, and I knew that I set my bridging header fine, because I had some other lib working.

When I copied library (drag and drop) into the project, without Cocoapods, only after that I could import headers without errors.

I used facebook/Shimmer library.

This happened to me after adding/renaming current configurations and it makes sense.

Every configuration makes use of Configurations Set generated by cocoapods so these 
things needs to match.

So if you add/rename configurations, these will need to use the right configuration sets, and for that running <code>pod install</code> will do it.

In my case I wanted to use a Swift protocol in an Objective-C header file that comes from the same target and for this I needed to use a forward declaration of the Swift protocol to reference it in the Objective-C interface. The same should be valid for using a Swift class in an Objective-C header file. To use forward declaration see the following example from the <a href="https://developer.apple.com/documentation/swift/imported_c_and_objective-c_apis/importing_swift_into_objective-c" rel="nofollow noreferrer">docs</a> at Include Swift Classes in Objective-C Headers Using Forward Declarations:

<pre><code>// MyObjcClass.h
@class MySwiftClass; // class forward declaration
@protocol MySwiftProtocol; // protocol forward declaration

@interface MyObjcClass : NSObject
- (MySwiftClass *)returnSwiftClassInstance;
- (id &lt;MySwiftProtocol&gt;)returnInstanceAdoptingSwiftProtocol;
// ...
@end
</code></pre>

If you are using Cocoapods, try:
<ol>
<li>Quit Xcode</li>
<li><code>pod deintegrate</code></li>
<li><code>pod install</code></li>
</ol>
For me, this solved the weird issue.

I have a Swift project for which I'm trying to import ObjC-based frameworks. The framework is located in a directory under the project's path and is referenced by the project in Xcode. It's also added to the "Link Binary with Libraries" in the project's 'Build Phases' page.

However, for some reason, I can't seem to include the framework in the Bridging-Header file. I get the following error:

<pre><code>BridgingHeader.h:5:9: error: 'Parse/Parse.h' file not found
#import &lt;Parse/Parse.h&gt;
 ^
&lt;unknown&gt;:0: error: failed to import bridging header 'BridgingHeader.h'
</code></pre>

Things I've checked:

<ol>
<li>The "Install Objective-C Compatibility Header" is set to "YES".</li>
<li>The Header Search Paths includes the path to the frameworks.</li>
</ol>

I'm sure I'm missing something, so if anyone has any clues, that would be great.

我有一个Swift项目，我正在尝试为其导入基于ObjC的框架。该框架位于项目路径下的目录中，并由Xcode中的项目引用。它还被添加到项目的“构建阶段”页面中的"Link Binary with Libraries“中。但是，由于某些原因，我似乎不能将框架包含在桥头文件中。我得到以下错误：BridgingHeader.h...
