Expertise with the SwiftUI life cycle
We can’t build UI screens without fully understanding the UI life cycle. States and modifiers such as onChange and onAppear are integral to the SwiftUI life cycle and essential to building a functional application.
We already went on some of the things related to the SwiftUI life cycle in the previous sections – for example, observed objects and states are part of the SwiftUI life cycle. Now, we must understand how they work when a view needs to reload, change, or move to a new screen.
