Chapter 4 - Vision: Image Similarity

[andrefrank]

Dear authors,
the comments in your book and also the method
func similarity ( to image : UIImage ) > Float ? { ....

implies that 'computeDistance' from the Apples' Vision framework returns the similarity between two images. For my understanding the method computes how much different images are.

So, if the value of the variable 'similarity' is '0' that means the images are 100% equal. Please correct me if I'm wrong.

The correct output at Line 66-69 in 'ContentView.swift' should be something like

 Text(
                        "Similarity: " + 
                        "\(similarity >= 0 ? String(100-similarity) : "...")%"
                    ).font(.title).bold()

Kind regards
Andre
