Deep linking itself has minimal impact on frame rate or battery life because it mainly triggers navigation actions. However, improper handling of deep links can cause delays if the app loads heavy resources or waits for network data before showing content. Efficient deep link handling ensures smooth user experience without UI jank.
To keep navigation smooth, parse and validate deep link URLs quickly on app launch or resume. Avoid blocking the main thread with heavy processing. Load only essential UI first, then fetch additional data asynchronously. Use lightweight placeholders if needed to prevent UI freezes during deep link handling.
Supporting deep linking requires minimal additional code and no large libraries, so bundle size impact is negligible. However, if deep links trigger loading of large resources or modules, startup time can increase. Use modular design to load features on demand and keep initial app launch fast.
On iOS, deep linking uses Universal Links configured via Apple App Site Association files and handled in AppDelegate or SwiftUI lifecycle. It requires HTTPS and domain verification. Android uses Intent Filters declared in the manifest and supports App Links with domain verification. iOS does not require explicit user permission for link behaviors; Android offers more flexible link handling but requires careful intent filtering to avoid conflicts.
It is likely your deep link handler is blocking the main thread by loading heavy data synchronously or waiting for network responses before showing UI. To fix this, parse the link quickly, show a lightweight screen immediately, and load data asynchronously to keep the app responsive.
