Why am I getting a fatal error when I run the code so far in my program?

My forecastURL is being set to nil for some reason. When it reaches the NSData withContentsOfURL method it crashes because it is trying to force unwrap forecastURL when it is nil. However, it should not be nil.

So it turns out the coordinates that I was copying from Google maps were causing the program to break. I typed the coordinates in manually instead of copying it and it worked fine. So further notice to others doing this track, you should probably just type it, don't copy paste

If you copy and paste from Google maps, just remove the space between the coordinates.
