Just having a comment given that the button’s motion isn’t extremely appealing – definitely we need to make it established picked to a random element in the pursuits array.
Once that’s performed, Xcode will build The brand new venture for yourself, then open up ContentView.swift for editing. This is where we’ll publish all our code, and you simply’ll see some default SwiftUI code in there for us.
