Once that’s carried out, Xcode will build The brand new challenge for you, then open up ContentView.swift for enhancing. This is when we’ll generate all our code, and you’ll see some default SwiftUI code in there for us.

Second, instead of normally demonstrating a blue history, we can easily choose a random colour each time. This will take two measures, commencing having a new home of all the colors we wish to pick out from – put this next to the things to do residence:
