# PDIAP-16167 - AccountLink - XFlow causing web view rewrites investigation
|
|
|
|
## Status
|
|
|
|
- Root cause identified and verified
|
|
- Confluence report requested by Jeff; draft sent for review
|
|
- Jeff approved creating the story
|
|
|

|
|
## Context
|
|
|
|
- Discourse 30181: FTTransfer (Zachary) reported that the AccountLink webview reloads / goes blank when the user taps the exit button in the FTTransfer playground.
|
|
- Zachary believes the issue is "new" and linked to a recent XFlow version change.
|
|

|
## Confirmed Findings
|
|
|
|
- **Root Cause:** SwiftUI Identity Reset (Modifier-Site Teardown). The `.ftFullScreenCover` modifier was anchored to a volatile branch inside `BankInformationView`. When the webview triggered an exit alert, the environment republish dismantled that volatile branch and rebuilt the presenter off-screen, causing the blank screen.
|
|
- **XFlow is NOT the cause:** XFlow eventing fires once to toggle a boolean and exits. The teardown happens later on a local JS/alert callback. XFlow does not mutate view identity, host lifecycle, or alert state.
|
|
- **v0.1.0 Rollback Proof:** The issue persists identically when rolling back XFlowSDK to v0.1.0 (pre-REST, pre-Apollo removal), empirically proving the defect is decoupled from the SDK's recent evolution.
|
|
- **Comparative Analysis:** The non-XFlow entry point (Zachary's alternative flow) survives because it uses a stable coordinator boundary (`BankSetupContainerView` / `NavigationStack`), bypassing the fragile modifier placement.
|
|

|
|
|
## Verified Resolution
|
|
|
|
- Moving the `.ftFullScreenCover` and the `shouldShowWebView` observer to the **stable root** of `BankInformationView` resolves the issue. Pure SwiftUI fix, no UIKit workarounds needed.
|
|
- Jeff acknowledged the fix and asked to include it in the Confluence report.
|
|

|
|
## Current Guidance
|
|
|
|
- Jeff's direction: document the findings clearly in a Confluence report, send it to Zachary, and comment it on the story. No need to fix their code directly; clear communication of the issue is the goal.
|
|
- Jeff also asked to include a version comparison showing that recent REST/GraphQL changes to XFlowSDK do not intersect with this flow.
|
|

|
|
|
|
## Next Step
|
|
|
|
- Finalize and publish the Confluence report with all findings, the v0.1.0 rollback evidence, and the XFlowViewMaker version comparison.
