Nullability crash

[AlbertRenshaw]

let out = UIImage(pixelBuffer: result!.out_p1)

This line causes entire app to crash with certain images.

Recommend switching corresponding lines to:

guard let in0 = buffer(from: resize) else {
            return nil
        }
        guard let result = try? model?.prediction(in_0: in0) else {
            return nil
        }
        guard let out = UIImage(pixelBuffer: result.out_p1) else {
            return nil
        }
