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
My addition to Daniel Kroms answer:
Never add -Swift.h Header to header. Even if it seems to work. Add the Import to .m file only!
In case you use in your header swift classes, make a forward declaration with @class swiftclassname before your @interface
Then you will see your real errors in your code.
