# PDIAP-15836 - Modernize dismissal delegate lifecycle sequencing for pure SwiftUI environment
|
|
|
|
## Status
|
|
|
|
- Moved to In Progress on May 7.
|
|
- David found a possible minimal dismissal fix path that would not require removing `UIHostingController`, and was validating it.
|
|
- Jeff directed David to do this dismissal/lifecycle work together with `PDIAP-12284` in the same branch because both changes are disruptive enough to require consumer testing.
|
|
- Sequenced after `PDIAP-15838` source work, but merge/release is delayed until after REST-transition consumer validation
|
|
- Sized at `8` points
|
|

|
## Context
|
|
|
|
- This story came out of the `AccountLink` root cause investigation.
|
|
- It is tied to the dismissal sequencing problem found after UIKit removal in SwiftUI-only paths.
|
|
- The root cause document was updated and the revised wording was approved.
|
|
|

|
## Approved Scope
|
|
|
|
- Modernize dismissal delegate lifecycle sequencing for pure SwiftUI flows.
|
|
- Cover the missing lifecycle contract where delegate callbacks can happen before the view is fully removed.
|
|
- Validate the change across affected SwiftUI flows rather than only in one narrow reproduction.
|

## Sequencing And Dependencies
|
|
|
|
- This story should come after `PDIAP-15838`.
|
|
- `PDIAP-12284` is the original UIKit-wrapping removal story and was reopened after rollback.
|
|
- Current working relationship: implement and validate `PDIAP-15836` together with `PDIAP-12284` in the same branch unless direction changes. David identified a possible isolated/minimal fix path, but Jeff prefers combined branch work because consumer testing is required either way.
|
|
- It is aligned with epic `26Q2 - Updating XFlowSDK to Decouple and Fix ApexKit Dependencies (Split Part 2)`.
|
|
- If possible, it should use the same consumer-impact feature flag strategy as the broader UIKit-removal rollout.
|
|
- Expect a long-lived branch: after implementation, maintain the branch until consumer-testing approval. Jeff expects the GraphQL-removal branch to merge first after the REST validation period, then that branch should be merged into the `PDIAP-15836` / `PDIAP-12284` branch. Current estimate is roughly 90-100 days from 2026-05-05 unless Fidelity shortens the review windows.

## Communication Notes
|
|
|
|
- Keep the scope framed as lifecycle sequencing in a pure SwiftUI environment, not only as a symptom like multiple modal presentation.
|
|
- If mentioned externally, keep it separate from `PDIAP-15838`.
|
|
- The Confluence/root-cause document was updated to reflect that FTTransfer changes are not the primary need anymore.
|
|
- The primary recommendation is to adjust the dismissal handling/sequencing correctly in the hosting path.
|
|
- FTTransfer improvements can still be mentioned as a secondary improvement, but not as a required change to reproduce the same visual behavior.
|
|
- When explaining why code still remains, clarify that the spike identified and documented the root cause, but implementation changes have not yet been published.
