Notion Migrates UI to SwiftUI as Apple Pushes Faster Native Apps at WWDC 2026

Apple used WWDC 2026 to confirm Notion is moving its interface to SwiftUI, signaling a deeper shift away from the productivity app’s long-criticized Electron and web-based architecture.
Performance and UI consistency drove the move, Apple said, after Notion’s existing stack struggled to match native responsiveness on Mac.
2025 already saw Notion push most of its iOS and Android experience to native code, with the editor still a notable holdout; the WWDC mention suggests that migration is now expanding substantially on Apple platforms.
Apple tied the example to broader SwiftUI changes, saying AI-assisted coding makes Swift porting easier and highlighting updates including up to 2x faster nested stack resizing, lazy state-object initialization and automatic HTTP caching in AsyncImage.
