Appium Launcher in AppiumGUI

Hello everybody.
Can somebody tell me does Appium GUI must have a safari launcher? If not, how i can add this launcher to appium?
I tried to add it. I have tried to compile project from github (https://github.com/budhash/SafariLauncher) and put compiled archive to appium.
When I try to use it - safari was launched, but I had the error, that launcher can’t find the button.
What I need do?

Thanks & regards

Console log

My java code:

public static void main(String[] args) {
        DesiredCapabilities safari = new DesiredCapabilities();
        safari.setCapability("browser", "Safari");
        safari.setCapability("platformName", "iOS");

        AppiumDriver driver = null;

        System.out.println("Before connect to server");

        try {
            driver = new IOSDriver(new URL("http://192.168.10.42:4723/wd/hub"), safari);
        } catch (MalformedURLException ex) {
            System.out.println(ex.getMessage());
        }
        System.out.println("After connect to server");

        driver.get("http://www.google.com/");

        System.out.println(driver.getTitle());
        driver.quit();
    }
