Getting error for declaring swift protocol delegate variable in objective c

Error: Can not find protocol declaration for 'GameDelegate';

//Swift protocol
import AVFoundation
import UIKit;

@objc protocol GameDelegate {
    func lostConnection()
}

Objective C class:

//play.h file
#import "SimpliSafe-Swift.h"

@interface SSStreamManager : NSObject 

@property (assign) id<GameDelegate> delegate

@end
Solution

  • Don’t import the Swift generated header into a header file! Replace

    #import "SimpliSafe-Swift.h"

    With

    @protocol GameDelegate;
