SwiftUI is a modern, declarative framework for building user interfaces on Apple platforms. One of the key features it provides is the use of property wrappers, which are a way to add functionality to properties in your SwiftUI views.
Property wrappers are defined using the
@ symbol, followed by the name of the property wrapper. Here is a list of all the property wrappers available in SwiftUI:
@State: This property wrapper allows you to store and modify a value within a view. When the value changes, the view will automatically update to reflect the new value.
@Binding: This property wrapper allows you to create a two-way binding between a value and a view. When the value changes, the view will automatically update to reflect the new value. When the view changes, the value will also be updated.
@ObservedObject: This property wrapper allows you to store and observe an object that conforms to the
ObservableObjectprotocol. When the object changes, the view will automatically update to reflect the new values.
@Environment: This property wrapper allows you to access global environment values, such as the current device, color scheme, and more.
@EnvironmentObject: This property wrapper allows you to store and observe an object that conforms to the
ObservableObjectprotocol and is available globally throughout your app.
@FetchRequest: This property wrapper allows you to execute a fetch request on a Core Data managed object context and store the results in a property.
@ScaledMetric: This property wrapper allows you to access scaled metric values, such as font sizes and spacings, that are automatically adjusted based on the user’s preferred content size.
@GestureState: This property wrapper allows you to store the state of a gesture, such as a drag or a long press, within a view.
@Published: This property wrapper allows you to automatically publish a value when it changes, making it easy to observe and react to changes in your view’s data.
@AppStorage: This property wrapper allows you to store and retrieve values in the user’s app storage, such as preferences or settings.
@SceneStorage: This property wrapper allows you to store and retrieve values in the user’s scene storage, which persists between app launches and is specific to a particular scene.
