QT Destructor not being called

I have problem with qt console application, destructor of MyServer class is not being called. Here is my simplified code:

#include <QtCore/QCoreApplication>
#include "MyServer/myserver.h" 
int main(int argc, char *argv[])
{

    QCoreApplication a(argc, argv); 
    MyServer server;
    server.startServer();
    return a.exec();

}

myserver.h

class MyServer : public QTcpServer
    {
        Q_OBJECT

public:
    MyServer(QObject *parent = nullptr);
    ~MyServer();
    QFile* file;
}

myserver.cpp

MyServer::MyServer(QObject *parent)
    : QTcpServer(parent)
{
    file = new QFile("file.ini",this);

}


MyServer::~MyServer()
{
    QSettings settings(file->fileName(), QSettings::IniFormat, this);
    settings.beginGroup("testGroup");


    settings.setValue("testValue", "asdf");
        settings.endGroup();
}

Destructor should change the file.ini, but it doesnt.

MyServer::file might be your problem. Are you opening that file for write access somewhere else in your code? Because QSettings will attempt to also open the same file, and your two concurrent accesses to the same file might be clobbering its contents.

If you don't need MyServer::file for anything, then get rid of it. QSettings does not need QFile. It only needs the filename.
