Copy a file with CMake

Copy Podfile at the build stage:

message("Copy ${CMAKE_CURRENT_SOURCE_DIR}/Podfile -> ${CMAKE_BINARY_DIR}")
add_custom_target(copy_podfile
    COMMAND ${CMAKE_COMMAND} -E copy_if_different
        "${CMAKE_CURRENT_SOURCE_DIR}/Podfile"
        "${CMAKE_BINARY_DIR}"
    COMMENT "Copying Podfile"
)
add_dependencies(${PROJECT_NAME} copy_podfile)

Copy Podfile at the configuration stage:

execute_process(COMMAND ${CMAKE_COMMAND} -E copy_if_different
    "${CMAKE_CURRENT_SOURCE_DIR}/Podfile"
    "${CMAKE_BINARY_DIR}"
)

Application folder does not exist when MacOS app is run the first time

When my QT app starts first time on MacOS, its directory ./Application Support/Sharlines/Lines/ does not exit, but QT creates it when I write to QSettings first time.

To create the local directory I added the following code:

// Local data directory does not exist when the app is run first time on MacOS.
if (fs::create_directories(GetLocalFolder()))
{
    qDebug() << static_cast<QString>(qtil::Format() << "Local folder '" << GetLocalFolder() << "' has been created.");
}

Generating QR code for my app

First I created a PHP file lines-app-store.php on sharlines.com website with the following content:

<?php

$iPod = stripos($_SERVER['HTTP_USER_AGENT'],"iPod");
$iPhone = stripos($_SERVER['HTTP_USER_AGENT'],"iPhone");
$iPad = stripos($_SERVER['HTTP_USER_AGENT'],"iPad");
$macOs = stripos($_SERVER['HTTP_USER_AGENT'],"Mac");
$Android= stripos($_SERVER['HTTP_USER_AGENT'],"Android");

//check if user is using ipod, iphone or ipad...
if( $iPod || $iPhone || $iPad || $macOs)
{
        //we send these people to Apple Store
        header('Location: https://apps.apple.com/app/id6504194961');
}
else if($Android)
{
        //we send these people to Android Store
        header('Location: https://play.google.com/store/apps/details?id=net.geographx.LinesGame');
}
else
{
        //we send these people to Windows Store

Using Swift in a QT6 app

I simply opened arboreus_examples/qt6/CMake/UsingSwift/UsingSwift_v3/CMakeLists.txt in QT Creator and was able to build it and run.

In its main.cpp it creates a Swift wrapper and calls method:

ASwift* oSwift = new ASwift(&oEngine);
oSwift->mInit();
_A_DEBUG << oSwift->mString();

My first attempt to build Yandex Mobile Ads Example for iOS

According to the official repository docs I tried to install CocaPods:

 sudo gem install cocoapods

but got the following error:

ERROR:  Error installing cocoapods:
        The last version of drb (>= 0) to support your Ruby & RubyGems was 2.0.6. Try installing it with `gem install drb -v 2.0.6` and then running the current command again
        drb requires Ruby version >= 2.7.0. The current ruby version is 2.6.10.210.

Installed some dependencies and the installation of CocoaPods succeeded:

sudo gem install drb -v 2.0.6
sudo gem install activesupport -v 6.1.7.8
sudo gem install cocoapods

Version tolerant serialization in C++

Last time I have been working on a C++ binary serialization framework that allows to serialize simple data structures with a few lines of code. First, you add AWL_REFLECT macro to all your structures as follows:

#include "Awl/Reflection.h"
#include <string>
#include <vector>
#include <set>

struct A
{
    int a;
    bool b;
    std::string c;
    double d;

    AWL_REFLECT(a, b, c, d)
};
