Interactive iOS design engineering systems

Live iPhone 16 Pro Titanium mockups — not static screenshots. Toggle screens, drag spring sheets, switch EN/ES locales, and inspect the motion specs underneath.

Selected systems

Shipped iOS interfaces — interactive, not screenshots

Three flagship systems inside live iPhone 16 Pro Titanium frames. Toggle screens, drag sheets, switch locales, and inspect the design engineering behind the motion.

BawoSocial — Interactive Motion

Design engineering lens

Shared-element event poster transitions into detail with spring interruptibility.
Spring-physics tab and sheet choreography tuned for thumb-reach interaction.
Skeleton shimmer shaders while feeds hydrate; Figma-to-SwiftUI token parity for the Obsidian & Copper system.
Optimistic real-time chat message physics — messages commit locally then reconcile with the server.

Design engineering specs

UIHostingController + UIViewRepresentable bridging mature UIKit navigation controllers with declarative SwiftUI form cells.
UIViewPropertyAnimator — interruptible accordion and dropdown transitions (try the reason-code picker).
Live English/Spanish string-expansion layout resilience with Dynamic Type and VoiceOver accessibility.
Offline-first state transitions for field connectivity gaps.

Under the hood

iOS Motion & Engineering Lab

Interactive controls for hiring managers and design engineers — spring physics, shared-element transitions, Dynamic Type, Reduce Motion, and localization stress tests.

Spring Physics & Gesture Interruption

Tune response, dampingFraction, blendDuration — previewing withAnimation(.spring(...)) vs UIViewPropertyAnimator.

dampingFraction0.78

blendDuration0.15

stiffness 320 · damping 31

matchedGeometryEffect

Shared-element card-to-sheet transition. Tap the card — the geometry morphs into the sheet surface.

Dynamic Type · Reduce Motion · Locale

Stress-test string expansion and type scale the way VoiceOver / Dynamic Type users experience shipping UI.

Dynamic TypeMedium

Spring sheet preview

Drag response & damping to preview withAnimation(.spring). Interruptible like UIViewPropertyAnimator.
