State

@propertyWrapper
public class State<Value>

Represents a mutable value to be held by a View. Reading a state’s wrappedValue property inside a view’s body computed property will trigger a subscribption by the view to listen to changes in the state’s value.

Important

You shouldn’t modify a state’s wrapped value when the view’s body property is being read.
