Strange issue 'Cannot find type 'RCTResponseSenderBlock' in scope' on Swift module React Native

I have a very strange problem: "Can't find the type RCTResponseSenderBlock in scope." It's strange, because in one case it is there and in the other it doesn't, looks like a bug.

This is screenshot issue.

This my Objective-C file:

#import <Foundation/Foundation.h> #import "React/RCTBridgeModule.h" #import <React/RCTEventEmitter.h> #import <React/RCTConvert.h> @interface RCT_EXTERN_MODULE(BLEclass, NSObject) RCT_EXTERN_METHOD(addEvent:(NSString *)name callback:(RCTResponseSenderBlock)callback ) @end 

And this my Swift file, where i have issue :

import Foundation @objc(BLEclass) class BLEclass: NSObject{ @objc(addEvent:callback:) func addEvent(_ name: String,_ callback:RCTResponseSenderBlock){ NSLog("%@", name); let resultsDict = [ "name" : name ]; callback([NSNull(),resultsDict]) } } 

If you know how to fix it, please write answer.

Thanks.

I had this same issue and discovered I had to add the import to my main bridge file.

#import <React/RCTBridgeModule.h> #import <React/RCTViewManager.h> 

I out which file was set by looking at the Build settings under Swift Compiler - General -> Objective-C Bridging Header which appears to be the default for the app.

I resolved the issue by adding

#import <React/RCTViewManager.h> #import <React/RCTConvert.h> #import <Foundation/Foundation.h>
