I have an iOS project written with Objective-C. I created an Swift class in the project, the bridging header file for accessing objective-c in Swift is generated successfull
OMG.. the actual import statement was not "class-Swift.h" but rather "projectname-Swift.h"
You can find the name of the file if you look under build settings->Swift Compiler Code Generation -> Objective-C Generated Interface Header Name
The file was not generated when I dragged in Swift source into the GUI. Only when I right-clicked->Add file to "project". It then asked to generate the header files.
