Xcode MyProjectName-Bridging-Header.h does not exist

ios objective-c xcode swift

I want to start using Swift in my Objective-C project. So i added a swift class:

import Foundation
@objc class System : NSObject {
    @objc func printSome() {
        println("Print line System");
    }
}

And imported it into a .m file:

#import "MyProjectName-Swift.h"

When building my project i get the following error:

Bridging header 'PathToMyProject/MyProjectName-Bridging-Header.h' does not exist

NOTE: Under "Build Settings->Swift Compiler - Code Generation->Objective-C Briding Header" is set to MyProjectName-Bridging-Header.h

What should i do to solve this issue?

Any help is much appreciated.

MyProjectName-Swift.h and MyProjectName-Bridging-Header.h work in opposite directions. MyProjectName-Swift.h is provided automatically. MyProjectName-Bridging-Header.h, however, is provided semi-automatically, i.e. you have to make sure it's there. So, are you sure that you can see MyProjectName-Bridging-Header.h in your project navigator? If not, create and add a file with that name to your project. Then check again that the path to it in the Build Settings is correct (it should include your project directory: MyProjectName/MyProjectName-Bridging-Header.h.

Have you checked your product module name is not empty? (Build Settings -> Packaging -> Product Module Name)

Nina, yes my module name is "MyProjectName" and not something ells

milos, I thought Xcode was supposed to auto generate this briding file. So no I don't have that file in my project.

Have you manually specified the Bridging-Header.h? I see, there is a spelling mistake 'Briding'

For me it does not fix at all. It looks that XCode does not react to the updated Objective-C Bridging Header field.

Took to long for me to find, but finally. Thanks, fixed the error :)

Well demonstrated! And yes don't forget to do this in both your Project Build Settings and as well as in Target Build settings.

I found that after creating the bridging header file manually and choosing the default name and location, the bridging header will be placed in the project directory, which is under the root directory.

This requires the following value for the setting: Targets > [Your App Target] > Build Settings > Swift Compiler - Code Generation > Objective-C Bridging Header:

$(SRCROOT)/$(PROJECT_NAME)/$(PROJECT_NAME)-Bridging-Header.h

Note that if your project is a swift module (framework) then, as pointed out in the comments, you might prefer:

$(SRCROOT)/$(PROJECT_NAME)/$(SWIFT_MODULE_NAME)-Bridging-Header.h

$(SRCROOT)/$(PROJECT_NAME)/$(SWIFT_MODULE_NAME)-Bridging-Header.h will be more common :)

this should be the only answer!

$(SRCROOT)/$(PROJECT_NAME)/$(SWIFT_MODULE_NAME)-Bridging-Header.h upto my project folder I am getting the correct path but appending /$(PROJECT_NAME) not taking me to the desired path.

Note for others who might have the same issue - When I copy/pasted @gaussblurinc comment there was some strange character copied in the 'Header' portion of the string. After copy/pasting the same string from the answer, it worked fine.

For those who are removing the Bridging Header

I was going the opposite way as most of the other answers here. I had been using a Bridging Header previously, but I didn't need it anymore. After I deleted it from my project I started getting the error mentioned in the question. I performed the following steps to solve my problem.

Go to Targets > [Your App Target] > Build Settings > Swift Compiler - General > Objective-C Bridging Header and delete the path. (Thanks to @Donamite for the idea.) （You can just start typing "bridging" into the search box to find it.) Delete the derived date. Go to Xcode > Preferences > Locations and click the gray arrow by the Derived Data folder. Then delete your project folder.

In Swift 4.1

your project you don't have bridging-Header.h file, but your project has that path. For this you need to delete that path...

Delete the bridging-Header.h file in Swift Compiler - General

I had this after creating a notification service extension, deleting fixed it.

These are steps to create Bridging header.

File->New->iOS->Header File, Give the bridging file name as like "yourProjectName-Bridging-Header.h" Build-Settings->Objective-C Bridging Header, Just give the bridging header file name be like "ProjectName-Bridging-Header.h" NOTE: Bridging header file should be located in the main root folder of the project where the ".xcodeproj" file located. If not move the Bridging header file to the root folder of the project. This way Xcode able to access the bridge file. Build the project, and import necessary files in Bridging header.

To add Bridge File in Swift project.

Step 1. Go to File > Add Cocoa with Objective-C File (For temporary Purpose)

Now press Create Bridging Header Button

DONE YOU WILL GET BRIGDE FILE IN BUNDLE THANKS

For me it helped to use $(SRCROOT)/$(PROJECT_NAME)/ in front of my bridging header file path

This is a valid answer. It should not have been marked down. You can use $(SRCROOT) and $(PROJECT_NAME) as a guide to arrive at the right answer but you probably can't copy and paste every solution.

The solution presented in this answer actually has fixed my issue, thanks Srinivas Padidala

Go for it.$(SRCROOT)/$(PROJECT_NAME)/YourProjectName-Bridging-Header.h works for me............ Paste $(SRCROOT)/$(PROJECT_NAME)/ as it is .....do not add your Project name in place of $(PROJECT_NAME)

Antoine

For me it helped to use $(SRCROOT) in front of my Objective-C bridging header path.

$(SRCROOT)/swiftLibraries/swiftLibraries-Bridging-Header.h

Follow the steps below:

Delete bridging header file . . . (Maybe you create manually) and; Create new Swift file in Objective-C Project . . . (Not import, first create it)

Maybe these two things will help solve your problem.

Cody Gray

The following worked for me:

Bridging header file should be located in the main root folder of the project where the ".xcodeproj" file located. Move to project directory and drag and drop bridging header to root if it is inside any other folder. Correct spelling mistakes in header name. Clear Derived data Target -> Build Settings -> Swift Compiler : General -> Add Obj C Header name. Clean and run again.

Creating Bridging Header File Manually

First of all delete the Bridging header file which Xcode is created. And Select your project goto > Build Settings > Search the keyword. Swift Compiler - Code Generation. Click on Objective-C Bridging Header , delete that path. Now clean your Project.

Now select your project > Window in the navigation bar . Select Projects and delete your derived data from there.

Now create a new file , select the Source and then select the Header File and create your Bridging header file . File name must be your projectname-Bridging-Header.h and then create it

Select your project goto > Build Settings > Search the keyword. Swift Compiler - Code Generation. Click on Objective-C Bridging Header and now add the path in this Objective-C Bridging Header like projectname-Bridging-Header.h

Now import your classes into bridging header file and you can compile it your code easily.

Your bridging header file looks like this when you are creating your file manually.

What helped me was to move the file manually to the path mentioned in an error message. So:

I deleted the file (moved to trash) Moved it from trash to the path in an error message Later I also had to clean the project
