Mobile AI Apps: SwiftUI and React Native Patterns That Feel Native

Mobile AI fails when it feels bolted on: modal chat that blocks the task, unstreamed responses, or network-only features that die at events and airports.

Prefer in-context assistants over a separate chat tab. Surface suggestions inside the flow the user already has — compose, search, RSVP, support — and keep a clear way to dismiss or undo.

Stream tokens into the UI with careful layout stability. Jumping row heights and keyboard fights destroy trust faster than a mediocre answer.

Architect for provider swap. Wrap LLM calls behind a thin client with timeouts, retries, and a deterministic fallback path. On React Native and SwiftUI alike, treat the model as an unreliable dependency.

This is where AI consulting meets mobile craft: the model is only half the product. The other half is interaction design and crash-free delivery.
