Import Objective-c framework into Swift framework project

Question

I am building a framework in which I need to import some objective-c frameworks.

For now I need to import "Beaconstac.framework", but we can not add a bridging header in a swift framework project.

How can I use this framework in my project?

I tried:

import Beaconstac

But the compiler reports error "No Such Module"

Is there any alternative way to do this?

And this developer.apple.com/library/ios/documentation/Swift/Conceptual/… — Babak

Doesn't matter you creating framework or application. you should be able to add external files to your project by bridging ! or may be i didn't get your concern? — Babak

we can not add a bridging header if we are creating a framework in swift. — Krishna Verma

Steps to include an existing Obj C framework in a swift framework project

Say we are creating an “SwiftProj.framework" project in swift which internally has to use an Objective C “ObjC.framework”

Place the ObjC.framework in Frameworks folder, Link to Swift framework project via Linked Frameworks and Libraries, and create a module.modulemap file at the same level.
In module.modulemap

module ObjC{
    header "ObjC.framework/Headers/ClassA.h"
    export *
}

Create xcconfig file (File->New->iOS->Other->Configuration Settings file)
In xcconfig file

SWIFT_INCLUDE_PATHS = $(SRCROOT)/
MODULEMAP_PRIVATE_FILE = $(SRCROOT)/module.modulemap

Now you can access ObjC.ClassA in SwiftProj.framework

Do you have an example project for this?

nuynait Over a year ago

@girish, I tried this, but not working. How did you make it to work? Could you give me some hint on anywhere that I need to be careful about? Also when you create .xcconfig file, did you set the config path anywhere? Appreciate your help.

Scofield Tran Over a year ago

@Atul, where to place the xcconfig file? How the project recognize the xcconfig file, too? Could you give more detail about it

@Atul followed same steps. But got error header "ObjC.framework/Headers/ClassA.h" not found.

what if we are using CocoaPods? where should the module.modulemap file be located?

Create a file called module.modulemap and include the following contents:

module ObjCFrameworkName {
    header "ObjCFrameworkName.framework/Headers/ObjCFrameworkNameUmbrellaHeader.h"
    export *
}

Be aware that you need to have the correct path to your Obj-C framework's umbrella header which may differ slightly with what's listed in the example above.

If you are still stuck, I would strongly suggest taking a look at this project.

You need to import the Beaconstac framework in your umbrella header. That is, if you'd ordinarily use, e.g., #import <Beaconstac/Beaconstac.h> in an Obj-C bridging header, for a framework you need to put that in the umbrella header.

See this chapter in Apple's documentation for more info:
