I started learning Xcode and Swift just several days ago, and today I wanted to create a Facebook Login for a new app.
So I followed this video guide on youtube: https://www.youtube.com/watch?v=MNfrBdyEvmY
and everything worked fine, except at the last step when I click the login button on simulator nothing shows up.

Then I went back to Xcode and found these two errors:

I looked at other threads too but none of them seems to match my situation. I have no idea what I did wrong and I'm simply stuck here..
