The SwiftUI Design System War: Composition vs Progressive Disclosure

Jacob’s Tech Tavern • 1530 implied HN points • 17 Mar 26
🪑 Design UI
  1. There are two main ways to build a SwiftUI design system: idiomatic view composition and a progressive-disclosure style that centralizes options into simpler initializers.
  2. Progressive disclosure can be pragmatic for large projects because it reduces API surface and makes components easier to use, even though it departs from SwiftUI conventions.
  3. Pick the approach that fits your team and project scale, weighing the trade-offs between idiomatic composition and pragmatic simplicity.

  1. In UX design, smart defaults can be very powerful.
  2. Sometimes, a design that looks slick and communicates well may not perform as well as another in tests.
  3. Don't underestimate the impact of smart defaults in design choices.

Quiz Answers: What Happened in UX & AI in 2025?

🪑 Design UI
  1. AI is shifting value away from routine craft toward human skills like agency, judgment, and persuasion; tools like vibe coding and generative UIs let people state intent while AI handles implementation.
  2. UX practice must evolve with new interaction patterns for AI: design for long-running "Slow AI" tasks (return recaps, conceptual breadcrumbs, tiered notifications), use prompt-augmentation interfaces (prompt builders, parametrization), and optimize content for AI citation (GEO).
  3. AI will reshape organizations and the economy by lowering transaction costs and flattening firms, displacing many routine knowledge jobs while creating new roles (super-users, auditors, FDEs) and exposing gaps in how we measure value and ROI.

UX Roundup: AI Empathy | Transparency About Compute Limits | UI Modes | Seedream 4.5 | AI In/Out of Silicon Valley | Kling Speaks

  1. Patients tend to rate AI as more empathetic than human clinicians, and newer models are likely even better; however, empathy measures need stronger, more detailed instruments.
  2. AI inference is scarce and costly, so product interfaces must be transparently show limits and trade-offs with quota meters, graceful fallbacks, and realistic wait estimates.
  3. UI modes (like separate “AI mode”) usually reduce usability, so AI features should be integrated into workflows and avoid forcing users to switch modes.

A Fresh Look at Analytics

trydeepwork • 2 implied HN points • 08 Feb 26
🪑 Design UI
  1. The analytics view is redesigned to be cleaner and more opinionated, surfacing when focus actually happens.
  2. Time is grouped by objectives so you can quickly see how your week splits across goals.
  3. The page is scannable in under a minute and highlights concrete work done each week, reducing digging and interpretation.

AI Is First New UI Paradigm in 60 Years

Jakob Nielsen on UX • 7 implied HN points • 22 Jun 23
🕹 Technology UI
  1. AI is introducing the third user-interface paradigm in computing history, shifting from command-based interaction to intent-based outcome specification.
  2. The first UI paradigm was batch processing, where users submitted complete workflows and got results much later, usually with issues in usability.
  3. Command-based interaction, the second UI paradigm, allowed users to assess and modify commands one at a time, with GUIs dominating for about 40 years; AI's intent-based paradigm reverses user control, representing a new era in UI design.

🕹 Technology UI
  1. Remote rendering allows third-party code to define UI in a secure sandbox and render it in the host application.
  2. Benefits of remote rendering include ensuring consistent user experience, avoiding bundle explosion, and maintaining host performance.
  3. Secure implementation of remote rendering involves running third-party code in a sandboxed environment with restricted access to the host.

🕹 Technology UI
  1. New systems are born from the discovery of the right user interface for a technology, which lowers accessibility costs and incentivizes new applications.
  2. Apple has a history of seeding ecosystems by creating the right user interface - such as with graphical computing and mobile computing.
  3. The Vision Pro by Apple exemplifies the importance of UI innovation, especially for technologies like spatial computing, which has the potential for transformative impacts.

The Future Is Many Interfaces

🕹 Technology UI
  1. The future of interfaces is not dominated by a single type but includes multiple interfaces like voice, touch, and gesture.
  2. Human culture and social behavior greatly influence how user interfaces are experienced and developed, leading to a variety of UI options.
  3. Technological advancements are expanding UI possibilities, such as haptic interfaces and brain-computer interfaces, offering new ways to interact with the digital and physical world.
