Project requires a provisioning Profile

Hello everyone. I need some help. I just started the "Apple Pie" Project in the how to learn to code swift book. I tried to run the simple app in the iPad simulator. However, there's popping up the bug "...Project requires a provisioning Profile". I don't understand why I need to set up a profile. Until now I was able to run Simulators without any profiles/logins and so. What do I need to do?
