The fade comes about simply because SwiftUI sees the background colour, icon, and textual content altering, so it eliminates the previous sights and replaces it with new sights.

When that’s finished, Xcode will build the new undertaking in your case, then open up ContentView.swift for enhancing. This is when we’ll create all our code, and you’ll see some default SwiftUI code in there for us.
