The Power of SwiftUI “task” View Modifier
The
taskview modifier starts the unstructured async task and binds it to the view lifecycle. SwiftUI automatically cancels ongoing tasks whenever the view disappears by propagating cooperative cancellation.[…]
Another variant of the
taskview modifier allows us to observe equitable data and run the async task whenever the data changes. The task lifecycle is still bound to the view lifecycle, but SwiftUI also cancels the ongoing job whenever data changes and creates a new one for the latest data.[…]
Usually, we want to debounce requests to our servers and make them after a slight pause. We can quickly achieve this effect by leveraging the power of the cooperative cancellation and data observing capabilities of the
taskview modifier.
