Migrate from as! to guard let else fatalError(…) construct #6

I tend to avoid the use of force-unwrapping ! and force-casting as!.

I think it's preferable to use guard let x = y as? Y else { fatalError("…") } and use an explicit and helpful error in the fatalError(…) call rather than let x = y as! Y

There are not many force-casts in the codebase so that should be pretty quick to do.
