# 2026-05-12

## Focus

- Continue the combined `PDIAP-12284` / `PDIAP-15836` implementation path for SwiftUI host-mode routing and dismissal sequencing.

---

## Findings

- Copilot's inspection says the host-mode API appears new in the current branch and is not present on `main` in `XFlowSDK`; XFlowViewMaker's `FlowConfig` host-mode shape also differs from `main`. That makes neutral enum-case renaming safer within this branch, pending normal review.
- The current implementation keeps two host-mode enum types to preserve the module boundary: XFlowViewMaker owns host-selection policy and XFlowSDK owns presentation mechanics. Conversion is intended to stay in one place in `FlowViewBuilder` with an explicit boundary comment.
- Enum cases were renamed to neutral names: `swiftUIHost` and `uiKitHost`.
- The final feature flag key is `iOS-XflowUIKitHostEnabled`. Semantics: `true` uses the temporary UIKit host path; `false`, missing, unavailable, or unknown uses the SwiftUI host.
- Old host-flag key usage was removed rather than dual-supported because it was not found in current code search outside the branch context.
- `AnyView` was removed from `buildFlow` internals by making the builder path type-safe with `ViewBuilder`; `AnyView` remains only at the existing `FlowViewMaker` public API boundary where `makeFlowView` currently returns `AnyView`.
- Files reported changed: `FlowConfig.swift`, `FlowViewBuilder.swift`, `FlowViewMaker.swift`, and `XFlowManager.swift`.
- Validation reported: SwiftUI remains the default host mode; explicit UIKit host path preserves dismissal-completion behavior; delegate callbacks/session cleanup still happen after confirmed dismissal; existing `FlowConfig` standard init call sites remain compatible; edited files had no file-level diagnostics.
- Build validation is not green yet. XFlowViewMaker's module build failed because its podspec currently resolves `XFlowSDK 2.8.48`, which does not expose the new host-mode type/API. XFlowSDK SwiftPM validation in that environment is also blocked by registry configuration: no registry configured for the `fidelity-src` scope.
- After manual dependency/build handling, the Fid4 compile path is now green for the latest `FlowViewBuilder` shape. The source-level fixes moved setup side effects out of the `@ViewBuilder`, kept `@ViewBuilder` confined to host-view construction, and preserved internal type safety without reintroducing `AnyView`.
- `PDIAP-12284` was moved to In Progress. `PDIAP-15836` may become a subtask of `PDIAP-12284`; Jeff planned to ask Quy how to handle the Jira structure and story points.
- David explained that "host-mode resolution" is shorthand for deciding whether XFlow builds through the SwiftUI host path or the temporary UIKit/`UIHostingController` path. XFlowViewMaker makes that decision before calling XFlowSDK; SwiftUI is the default and UIKit is selected only when the flag explicitly enables it.
- For REST validation, David confirmed Fid4 can be pointed at production through a plist value, which is the preferred non-pushed path. Testing with the production plist still showed GraphQL being used in the tested case. Raj appears to have a production account for follow-up production validation.

## Next Steps

- Move to runtime validation now that compile is green: first run a representative Fid4/XFlow flow with the default configuration and confirm logs show the SwiftUI host path is selected.
- Then run a controlled UIKit-host experiment by forcing/simulating `iOS-XflowUIKitHostEnabled == true`, and confirm logs show the UIKit host path while preserving dismissal-completion behavior.
- Keep the evidence log-based and separate default SwiftUI behavior from the explicit UIKit-flag path.

## Blockers

- No current source-level compile blocker after manual dependency/build handling. Runtime host-path validation is still pending.
