How to solve the problem of "terminating with uncaught exception of type NSException"

Hi All,

I ama trying to build an app but recently ran into this issue and I am not sure how to go about solving it. I am new to xcode and swift in general and I have been teaching it to myself using guides and videos. Any thoughts on this error?
