Ios – Xcode 8 with mixed Swift and Objective-c project generated “ModuleName-Swift.h” header not found

Now it works.

1. Project must have a Product Module Name that does not include spaces.
2. Defines Module must be set to Yes in Build Settings, under Packaging.

Finally works. Thanks to everyone for the help :-)

I spent about 4 hours trying to enable Swift in my Xcode Objective-C based project. My myproject-Swift.h file was created successfully, but my Xcode didn't see my Swift-classes. So, I decided to create a new Xcode Objc-based project and finally, I found the right answer! Hope this post will help someone :-)

Step by step Swift integration for Xcode Objc-based project:

1. Create new *.swift file (in Xcode) or add it by using Finder.
2. Create an Objective-C bridging header when Xcode asks you about that.

3. Implement your Swift class:

   import Foundation
   
   // use @objc or @objcMembers annotation if necessary
   class Foo {
       //..
   }
   

4. Open Build Settings and check these parameters:

   • Defines Module : YES

     Copy & Paste parameter name in a search bar

   • Product Module Name : myproject

     Make sure that your Product Module Name doesn't contain any special characters

   • Install Objective-C Compatibility Header : YES

     Once you've added *.swift file to the project this property will appear in Build Settings

   • Objective-C Generated Interface Header : myproject-Swift.h

     This header is auto-generated by Xcode

   • Objective-C Bridging Header : $(SRCROOT)/myproject-Bridging-Header.h

5. Import Swift interface header in your *.m file.

   #import "myproject-Swift.h"
   

   Don't pay attention to errors and warnings.

6. Clean and rebuild your Xcode project.
7. Profit!
