Custom Storage

The iOS SDK persists two internal values and keeps both in UserDefaults. From 1.1.0 the storage engine is fixed: DetourConfig takes no storage adapter, so no storage adapter can be supplied.

What the SDK stores

Section titled “What the SDK stores”
  • DetourFirstEntranceFlag — set on the first launch, so deferred matching runs once per install
  • Detour_deviceId — a UUID generated the first time analytics send an event

Both are stored in UserDefaults.standard and are preserved across app restarts. Deleting the app clears them.

Reset for testing

Section titled “Reset for testing”

To run the deferred flow again on the same install:

Detour.shared.resetSession(allowDeferredRetry: true)

This clears the in-memory session guard and the first-entrance flag, so the next resolveInitialLink call attempts a deferred match again. The analytics device id is not changed.
