Objective c and Swift using in Framework in Xcode

Question

I've my own old framework which is only compatible in objective c, but Now I open in new xcode and added few swift classes (Xcode not gave me option to create bridging as this do in normal App when you add swift class in objective c project), Also Xcode gave me suggestion to update build setting and I updated those and currently I'm on Xcode 8.2.1. Now I try to build but I am getting few error as you can see in picture . I googled and found solution to delete derive data and quite xcode and open and clean. I done Everything but didn't workout.

Is bridging can be possible in framwork.
If not possible then how can I achieve.

Need help and suggestion.

@AshutoshDave No I don't have any swift file "ProjectName-Swift.h", I think this create because of bridging suggestion which I didn't get while adding new swift file — Aleem

When you are mixing Swift/Objc inside a framework, you can import Swift code for Objective-C use and import Objective-C from Swift.

First, ensure that Define Settings is set for the current framework target.

To import Swift into Objective-C: In each Objective-C file that requires the Swift code, import the generated Swift header with the complete current Framework Path : #import <Framework/Framework-Swift.h>

To import Objective-C into Swift:

Ensure you have an umbrella header. The path can be found inside the Build Settings of the target. In this header, import all the needed Objective-C headers like normally in Objective-C: #import "Header"

Awesome. Critical point here was that "Framework-Swift.h" did not work, it has to be imported using <Framework/Framework-Swift.h>.
