It works for one target but not the other. I have looked at build settings to see where this file is set but I can't find it.
#import "Wunder-Swift.h"
This gets me the error "file not found". I have no idea where to set this.
Wunder-Swift.h file can be found in Target -> Build Settings -> Objective-c Bridging Header.
Or you can search for "swift", it will show you.
If Wunder-Swift.h is not added in your project then just add a new Objective-C file, it will show an option to add a Bridging-Header file and automatically set your bridge file path.

I am trying to add many Objective-C files to my Swift project with folder reference mode that means when I drag and drop my files into project I am selecting "Create Folder Reference".
This is because all of my obj-c files use #include "/folder/folder/folder/" for example. These files are generated with j2objc project.
Now my problem is when I want to #import or #include some .h of these files in myproject-Bridging-Header.h Xcode can't find the header files.
I use #import "/folder/folder/folder/" like generated files but no chance.
I add $(PROJECT_DIR)/ in build settings - search header paths but it does need to write path completely like $(PROJECT_DIR)/folder/folder/folder/.
Is there any way to set main folder and Xcode find subfolders ? Or do I need to write every path separately ?
I found the answer after many days by myself!
When I drag and drop my files to my project in Xcode in mode "Create Folder Reference", just a reference to the files is added to Xcode and the files were in their folder where in my Mac.
I resolve this problem by add files to project's folder manually and then drag and drop from that location to Xcode. After that, I could access my file by its address in myproject-Bridging-Header.h like #import "/folder/folder/folder/file.h"
The bridging file is added, but keeps showing the error.
My Bridging Header File is correctly setup because the other imports are successful.
I would advise you to use CocoaPods to handle external frameworks. Here is SlackTextViewController. If you still want to use copied version, make sure you add the files to your project. Try copying the files to your project folder using Finder and then use Xcode File -> Add files to "YOUR_PROJECT"
I am facing build fail error after moving Bridging-Header
objective-c swift on xcode6.
Before I moved header file, it had been working fine.
The error shows header file not exist. The header file path remains still old path in error log. I tried build clean, but still old path remains.
How can clean the objc-header-path?
You need to update the path in your project's Build Settings to point to the new bridging header location.
Click your target and then click 'Build Settings' then search for Objective-C Bridging Header
You'll find the path to the bridging header in your target's Build Settings, under "Swift Compiler - Code Generation"/"Objective C Bridging Header".
I tried with Xcode6.1-Beta, as well.
But still impossible to update the objective-c header path.
I don't know where the configuration file is. I gave up to figure out.
Finally, I deleted the target xcode project and recreated new project.
Now it is working.
Yes it's possible.
Delete the .h file
Clear the path at Objective-C Bridging Header
Create new Objective-C File
Name your header file to the same name as before (popup will ask you to create new header file)
Goto File > Project Settings > Data Location
Make sure your path is correct and press "Done"
Your app should run again pointing to the right location of the header file and delete the files ModuleCache
Happens to me many times when i move app folder around.
I had a workspace that I was using when I had the same thing happen. I moved my project to a different folder. Despite having a relative path on my bridge headers, it was still referencing the old location when building and threw an error.
Here's what I did to fix this:
Close the workspace
Open the .xcworkspace file using TextWrangler. TextWrangler allowed me to navigate the package to /xcuserdata/[username].xcuserdatad/UserInterfaceState.xcuserstate. I did a search for the old path and found it. Make the change to the new location of the header file.
This by itself didn't fix it. After cleaning and building, the old value showed back up! Then I deleted the Build folder. It has a ModuleCache that I think was holding on to the old value as well.
After doing this, my project picked up my new value and I was able to build the project. I'm not certain step 2 is necessary. But it did store the old value in there.
In my case, I changed the path from relative path to absolute path and solved.
like
From:
project_name/project_name-Bridging-Header.h
To:
$(SRCROOT)/project_name/project_name-Bridging-Header.h
I have a project, which has a static library with references to header files like this:
#import <libetpan/libetpan.h>
I can't change this import line. What should I do, to make Xcode find those header files? I have a folder with header files, that I can import to the project. Thanks.
At the moment the error is following:
'libetpan/libetpan.h' file not found
You may have added the libetpan folder to your project (if not, do so)
right click on that folder and see the path (get info after right click)
if its not a sibling of your project file in the folder structure (check in finder), thats where its going wrong
alternately, you could add header search paths: header search path in XCode 4
How do I add c library to Xcode Cocoa project?
Or what is the best option, I don't want to copy them into Cocoa project directory.
I have a C project called a which compiles into library a.dylib and header file a.h, the project is located in it's own directory.
I want to use this library from my objective-c application in Xcode.
How do I add the header file and library to my Xcode project?
I can drag the a.dylib into other frameworks but what do I do with a.h?
I figured it out.
I point to location of project a deployment directory (headers) to Search Path in project settings either:
as Header Search Paths, if used as <a/a.h>
or into User Header Search Paths, if used as "a/a.h"
As for library I just drag it to Xcode project and set it to refer to library instead of copy.
Here are the steps before adding a header file test.h in your project. Here is the files location root -> Library -> include -> test.h
click on build settings
Find User Header Search path. add your header file location here. add following value to Debug, Release and Any Architecture field. $(SRCROOT)/Library/include. Your project Root is the folder that contains your project, it conatins .xcodeproj file.
After adding path you will be able to add header in like this
# include "test.h"
You can drag them both the .a and .h files to Xcode, but make sure to not check the "Copy items to project folder". As for referencing the header file, you'll need to put it in a place where you can add a path to it in your #include/#import statements. Is there a reason you don't want to copy the header to your project file?
