Yes, it is possible for SwiftUI's Identifiable
and Equatable
to stop a re-render occurring in ForEach
.
Identifiable
is a protocol that allows SwiftUI to identify each view uniquely. When views are identified uniquely, SwiftUI can efficiently update only the views that need to be updated.
Equatable
is a protocol that allows SwiftUI to compare two views and check if they are equal or not. If two views are equal, SwiftUI can avoid re-rendering the view.
By using Identifiable
and Equatable
protocols in combination, we can prevent unwanted re-renders in ForEach
loops. We can create views that are identified uniquely and can be compared efficiently, thereby minimizing the re-rendering of views.
