→Examples: The assertion that it's standard practice to separate app struct and view structs is common knowledge in the SwiftUI developer world but is difficult to cite. The assertion that the main view is called "ContentView" however is pure preference and personal style.

The following is an example of a simple [["Hello, World!" program|Hello World]] program. The {{code|@main}} attribute defines the entry point into the app. It is standard practice in SwiftUI to separate the application struct and views into different structs, according to the [[Model–view–viewmodel|Model–View–ViewModel]] (MVVM) architectural pattern.<ref>{{
