SwiftUI Lifecycle: How to Use SwiftUI for Optimal Performance
SwiftUI is a powerful new framework for creating user interfaces in Swift. It provides a declarative way of creating user interfaces, which makes them easy to read and maintain. In this blog post, we will take a look at the lifecycle of a SwiftUI app and learn how to use it for optimal performance.
When you create a SwiftUI app, the first thing that happens is that the AppDelegate is initialized. This is where you can put your initial setup code. Next, the scene is created. This is where your SwiftUI Views are rendered. Finally, the view hierarchy is created and the app is ready to run.
The lifecycle of a SwiftUI app can be divided into three phases: initialization, layout, and rendering. In each phase, there are different things that happen and you can use different APIs to perform actions. Let’s take a look at each phase in more detail.
Initialization
The initialization phase is when your app sets up its initial state. This includes creating the AppDelegate and scene, and initializing your SwiftUI Views. In this phase, you can perform any setup that is needed for your app. For example, you can load data from a remote API or create a database.
