SwiftUI's List is only lazy when SwiftUI can determine how many views a ForEach element resolves to without evaluating the closure. Two common patterns prevent this: - Using an `if` statement inside ForEach - Wrapping rows in AnyView In both cases, SwiftUI evaluates the ForEach closure for every element before any rows are displayed.
