From your picture, you are trying to use FB Login but haven't yet installed the Facebook SDK. Check out developer.facebook.com and sign up. Once you connect that to your project, it should run fine. The simple login is dependent on classes from this SDK to utilize facebook login. When it can't find them, your project crashes.
I am having trouble linking the Firebase Simple Login Framework to my project with an "Undefined symbols for architecture i386: error"
