I am planning to add two files from objective C, [PendulumView.h and PendulumView.m] to swift. But if I try to create bridging header, I am unable to create Bridging header. Xcode doesn't ask me "Would you like to create bridging header?". That dialog box also not appeared. If I proceed and I imported my header file, I am receiving error.

(Command + N) -> iOS -> Source -> Objective-C/Header file. No Bridging header is creating. Automatically, .h or .m file is created.

pendulum_header.h file

#ifndef pendul_test_pendul_Header_h
#define pendul_test_pendul_Header_h

#import "PendulumView.h"

#endif

ViewController file

override func viewDidLoad() {
    super.viewDidLoad()

    var pendul_object = PendulumView() //Error Receiving. Unresolved Identifier PendulumView

}

Screen shot is below:

Mistake is completely my side.

What I did?

  1. Open new project -> Imported that .h and .m file.
  2. Right Click -> New File -> "iOS -> Source -> Objective-C.m"
  3. .m file has been created, but bridging header not created.

What should do?

  1. Open new project
  2. Right Click -> New File -> "iOS -> Source -> Objective-C.m"
  3. Bridging header has been created with .m file.
  4. Then, Import that .h and .m file.

Try go to your project settings. In the Build Settings tabs go to the search field and search for bridging. In the following search result you should see: Swift Compiler - Code Generation with a setting for Objective-C Bridging Header. Change the value to your project path (where your project files are stored in) and you should be good to go.

At the top left corner, theres a button for Basic and All. Press the All button and it should show.
ya got it. How to find project path??
One easy way to do it is: click on a random (swift) file in your project. In your utilities panel (with all the options etc) there should be two icons. Click on the left icon looking like a document if it's not already selected. In the second section there's the full path of that file. Use that path (minus the file name you've clicked).
