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:
BridgingHeader.h:5:9: error: 'Parse/Parse.h' file not found
#import <Parse/Parse.h>
^
<unknown>:0: error: failed to import bridging header 'BridgingHeader.h'
Things I've checked:
I'm sure I'm missing something, so if anyone has any clues, that would be great.
This question is related to
swift
xcode
bridging-header
My framework was working before and suddenly stopped working, and none of these answers were working for me. I removed the framework in Build Phases > Link Binary With Libraries, and re-added it. Started working again.

Xcode 8. Swift Project - importing Objective C.
Things to know:
Clean project,Clean build folder,Restart Xcode. i just remove path at project goto > Build Settings > Search the keyword. Swift Compiler - General -> Objective-C Bridging header worked for me.
I had an issue and fixed it after spending 2 hours to find. My environment as below:
cocoapod 0.39.0
swift 2.x
XCode 7.3.1
Steps:
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 pod install
will do it.
In my case I just had to quit the simulator...
This error appeared when installing with Cocoapods the library CocoaImageHashing. The problem was that the search paths were wrong. So at the Target level, in Build Settings -> Search Paths -> Header Search Paths, the paths were corresponding to non existing folders, for example "${PODS_ROOT}/Headers/Public/CocoaImageHashing", when the folder structure Headers/Public/ did not exist. I added the path ${PODS_ROOT}/CocoaImageHashing and the error disappeared.
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.
I have the same issue. I changed all my imports from
#import "HMSegmentedControl.h"
to #import <HMSegmentedControl/HMSegmentedControl.h>
for example.
We encountered the same error message, with a completely different cause.
Setup:
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.
If using cocoapods, try reinstalling the pods by running the following command.
pod install
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 main.storyboard
and it took care of the error.
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.

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 docs at Include Swift Classes in Objective-C Headers Using Forward Declarations:
// MyObjcClass.h
@class MySwiftClass; // class forward declaration
@protocol MySwiftProtocol; // protocol forward declaration
@interface MyObjcClass : NSObject
- (MySwiftClass *)returnSwiftClassInstance;
- (id <MySwiftProtocol>)returnInstanceAdoptingSwiftProtocol;
// ...
@end
I had just duplicated an existing scheme and added another configuration to the project. I had to add a configuration with the same name to the framework's project in order for it to also build in the same DerivedData/($AppName)/Build/Products/($CONFIGURATION_NAME)
folder. Otherwise the .framework file doesn't get created and therefore can't be imported.
This somehow did the trick for me:
I had a similar issue with pods. Basically trying to run my UI tests, Xcode complained about missing pods. Solution to this was much simpler than any described above:
Working!
I found it in a thread: https://github.com/CocoaPods/CocoaPods/issues/2695
Sounds a bit like a bug for cocoa pods but I can see reasons why it might be tricky case.
I ran into the same issue today when trying to use a pod written in Objective-C in my Swift project, none of the above solutions seemed to work.
In the podfile I had use_frameworks!
written. Commenting this line and then running pod install
again solved this issue for me and the error went away.
I had to add my lib
directory in User Header Search Paths:
In my case the lib
directory contains the .a
-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 ${PROJECT_DIR}/lib
to the User Header Search Path it built the test target.
(I am using Xcode 6.2 on Mavericks 10.9.5)
If helps anyone.
In my case my obj-c files were added has a reference folder (the blue folders in xcode) and the header couldn't find them. Just added the files, not the folder, from the finder to xcode and solved.
