Hi,

Are you building for iOS ?

TuniDev

Yes, it's for iOS
I find the solution

ios: {
HEADERS +=../IOs/objectiveactivity.h\

OBJECTIVE_SOURCES +=\
../IOs/objectiveactivity.mm

OTHER_FILES += \
../IOs/objectiveactivity.mm

}
//*******************************************objectiveactivity.h
#pragma once
#include <QObject>

class ObjectiveActivity : public QObject{
Q_OBJECT
public:
ObjectiveActivity();

};
//*******************************************objectiveactivity.mm
#import "objectiveactivity.h"
#import <Foundation/Foundation.h>
ObjectiveActivity::ObjectiveActivity (){}
QString ObjectiveActivity::setConfigSetting(QString value){
NSLog(@"Value of string is %@", value.toNSString());
return "Good night, Gracie!";
