Redrawee — Investigating SwiftUI Views Redrawing Patterns

An iOS app that investigates effects of using different approaches in building view hierarchies and state managment on views redraws:

• Extraction of subviews into a separate structs and view modifying methods into view modifiers
• Usage of @ViewBuilder and its underlying _ConditionalContent view
• Passing values down the hierarchy through @Binding and through @Environment
• .id(_:) modifier
• Conforming your views to Equatable protocol and usage of .equatable() modifier
• Comparison of ObservableObject and @Observable approaches
