I try to integrate a SDK in my React Native code.
SDK is in Swift and the function I would like to call is fetchValue as below:

class SiVC: UIViewController, ExchServiceDelegate, UITextFieldDelegate {
... 
 func fetchValue(){
 ...

I added a addedSDKBridge.m to call RCT_EXTERN_METHOD, so that it is available in my react native app :

//addedSDKBridge.m
#import <UIKit/UIKit.h>
#import "React/RCTBridgeModule.h"
@interface RCT_EXTERN_MODULE(SiVC,UIViewController)
RCT_EXTERN_METHOD(fetchValue)
@end

But I have the following error:

Undefined symbol: _OBJC_Class_$_SiVC

I have read in this tutorial
that it is necessary to add @objc so I added @objc(SiVC) before class in the SDK and @objc before func but it didn't change the error

Do you know how I can correct this error and call the function from React Native ?
