you should use a bridging header. Please search to find more information about it.D. Greg– D. Greg2017-11-09 06:22:41 +00:00Commented Nov 9, 2017 at 6:22

I initially faced same trouble but after searching on web I got success. you should follow exact same as I have mentioned below:
Step by step Swift integration for Xcode Objc-based project:
Create new *.swift file (in Xcode) or add it by using Finder
Create an Objective-C bridging header when Xcode ask you about that
Implement your Swift class with @objc attribute:
import UIKit
@objc public class CustomView: UIView {
override func draw(_ rect: CGRect) {
// Drawing code
}
}
Open Build Settings and check those parameters:
Defines Module : YES
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
Import Swift interface header in your *.m file
#import "myproject-Swift.h"
Don't pay attention to errors and warnings. Clean and rebuild your Xcode project. Done!

Bro i have done YES and Product module name also but when i write header file it shows me the bridge header file only. @Umang Loriya
siddle
It shows only this #import "PK.House-Bridging-Header.h" in objective c class where i want to write header file.
Umang Loriya
Actually "PK.House-Bridging-Header.h" is for using Objective C files in Swift but what you need to do is simply add this to .m file where you need to use swift object #import "PK.House-Swift.h".

Bro i'm really sorry but i'm not getting the point. I have done the above part u said to do YES and change the name also, after doing this now what to do ? @Umang Loriya
Umang Loriya
let's assume that you have objective c class files named viewController so in viewController.m file you need to add this line to access swift class files :#import "PK.House-Swift.h"
