In the context of SwiftUI, the Publisher
sink does not specifically run at willSet
or didSet
. These are property observers in Swift that are used to observe changes to a property's value. The Publisher
sink is part of the Combine framework, which is used for handling asynchronous events by processing values over time.
In SwiftUI, state changes are typically managed using state properties, bindings, and observable objects, as discussed in the SwiftUI essentials session. SwiftUI automatically updates the UI when the state changes, but this is not directly related to willSet
or didSet
.
If you are interested in how SwiftUI manages state and updates views, you might want to explore the session on SwiftUI essentials, which covers state management and view updates.
