When you press Guorlin Premium button it takes you to a website

Now, when I press the Guorlin Premium button is not working, it does not take me to the website.

Answer 1

Just press option+shift+command+k and press Ok to clean the folder and try to run it on a real device instead of the simulator.

It definitely works, I had a similar problem with a similar code and it worked for me. No change in code is needed.
