Mobile — UI Component Libraries & Kits

UI component options vary sharply by stack. SwiftUI and Compose ship excellent first-party kits and don't really need third parties for most apps. Cross-platform stacks have a richer third-party landscape. For framework choice see iOS, Android, Flutter, RN deep, Compose Multiplatform.

SwiftUI / iOS

• ★ Apple's first-party SwiftUI — covers the vast majority of needs in 2026; Liquid Glass / Materials, Forms, Charts, MapKit views.
• swift-snapshot-testing (Point-Free) — companion for visual diff testing.
• SwiftUI-Introspect — reach UIKit underbelly when SwiftUI lacks a knob.
• Pow (Movin) — paid SwiftUI transitions / effects pack.
• swiftui-navigation (Point-Free) — better state-driven navigation primitives.

UIKit (legacy maintained)

• SnapKit / PinLayout — programmatic layout DSL.
• IGListKit — Instagram's diffing UICollectionView.
• Texture / AsyncDisplayKit — async UI for huge feeds.

Jetpack Compose / Android

• ★ Compose Material 3 — the default; Material 3 expressive themes ship with newer releases.
• Compose Foundation — primitives if you don't want Material.
• Accompanist — Google-led extras; many features have folded back into Compose proper.
• Coil 3 — multiplatform image loading; the default in Compose code in 2026.
• Glide / Picasso — older View-system image loaders.

Compose Multiplatform / KMP

• Material 3 for CMP — same Material widgets across iOS / Android / desktop / web.
• jb-compose-icons — large icon set.
• Cupertino-shape libraries (community) — for native iOS look in CMP; quality varies.

React Native

• ★ NativeWind — Tailwind for RN; the default styling layer in 2026.
• ★ Tamagui — universal styled components for iOS/Android/Web; tree-shakeable; very fast.
• ★ gluestack-ui v2 — NativeBase's successor; copy-in-source shadcn-flavored components for RN+Web.
• React Native Paper — Material 3 components for RN.
• NativeBase — sunset / superseded by gluestack-ui in 2024.
• React Native Elements — older general-purpose kit.
• unistyles — runtime-fast styling.
• Dripsy — responsive RN styling.
• Magnus UI — utility-styled.

Flutter

• ★ Material widgets + Cupertino widgets — built into the SDK.
• GetWidget — large widget catalog.
• forui — shadcn-flavored Flutter components.
• flutter_animate — simple expressive animation API.
• shadcn_flutter — community shadcn-style port.
• VelocityX — utility-style.

Cross-platform headless / primitives

• react-native-aria (Adobe) — accessible primitives; powers gluestack and others.
• tamagui-core — primitives without theme.

Form-shape components

• react-hook-form — works in RN.
• TextField / TextEditor — SwiftUI native.
• OutlinedTextField / TextField — Compose Material 3.
• See forms and specialized inputs for cross-platform input choices.

Pick this if…

• Native iOS: SwiftUI; reach for Pow / Introspect only when you need them.
• Native Android: Compose Material 3; everything else is supplementary.
• RN, default styling: NativeWind + your chosen kit (Tamagui, gluestack, Paper).
• RN, universal Web+RN: Tamagui or gluestack.
• Flutter, default look: Material + Cupertino widgets; add forui or GetWidget if you want shadcn-flavored design.
• CMP, accept Material on iOS: Material 3 + jb-compose-icons.
