Question about RatingView(rating: .constant(Int(book.rating)))

Forums > 100 Days of SwiftUI

Hey there,

At Bookworm SwiftUI Tutorial 7/10 Paul used RatingView(rating: .constant(Int(book.rating)))

I'm trying to grasp when / why he used .constant here as I want to make sure I understand everything that is going on rather than copy paste blindly. Any ideas?

Thanks! Ran

RatingView is used both in AddBookView and DetailView, however Paul decided that for this design the book rating should not be changed in the DetailView, only in the AddBookView.

So RatingView in DetailView is passed the book rating as a constant (binding).
