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.

Showcase 01

NEO-SOCIAL

Consumer event discovery & interactive checkout — iOS / SwiftUI / custom motion. Glassmorphic dark UI with matchedGeometryEffect card-to-detail transitions and velocity-aware spring sheet detents.

Design engineering specs

  • matchedGeometryEffect — card-to-detail shared-element transitions between feed posters and event detail.
  • Custom Animatable — blur/scale interpolation across interactive presentation states.
  • Velocity-aware pan — gesture recognizers drive interactive sheet detents; drag the taupe checkout sheet to dismiss.
  • Core Haptics — UIImpactFeedbackGenerator / CHHapticEngine synced to sheet snap points.
  • ProMotion 120Hz — frame-pacing verified in Xcode Instruments.

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.

UIViewPropertyAnimator-style

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.

About

Alex

Senior iOS Design Engineer

Design engineer focused on the last 10% of iOS craft — spring physics that feel interruptible, shared-element transitions that stay at 120Hz, and UIKit ↔ SwiftUI bridges that keep mature apps shipping.

Flagship work spans consumer event discovery (NEO-SOCIAL), diaspora community platforms (BawoSocial), and multi-locale enterprise field operations suites.
