feat(wallet): unify wallet lifecycle loaders behind an app-wide overlay - #1062
Conversation
📝 WalkthroughWalkthroughThe change introduces asynchronous SDK lifecycle management, serialized wallet and network transitions, an app-wide lifecycle overlay, completion-aware wallet wiping, and asynchronous shielded transaction lookup refreshes with explicit operation reasons. ChangesWallet lifecycle and shielded synchronization
Estimated code review effort: 5 (Critical) | ~90 minutes Merge Risk: 🟡 Moderate · up to The PR unifies wallet lifecycle progress handling, but wipe operations can still remain blocked indefinitely if runtime teardown stalls, and failed persisted-wallet loading can leave temporary runtime resources alive. These paths may prevent recovery flows from completing or cause follow-up wallet operations to race cleanup, so merge should wait for bounded teardown and failure-path cleanup or explicit owner acceptance.

WalletLifecycleTransitionStateinto its own file.This type is a published UI-presentation state machine plus an admission gate. It now lives in the same file as the runtime lifecycle pipeline, which already owns network switching, wallet switching, and full-reset teardown. The coding guidelines require one responsibility per file and call out exactly this accumulation pattern for a coordinator that gathers published UI state next to storage teardown.
Extract it to
WalletLifecycleTransitionState.swift. No behavior change is needed.As per coding guidelines: "One file = one responsibility — a 'coordinator' that accumulates published UI counters, storage wipes, and money movement gets split."

rethrowing; propagate try await through managerForWipe and both
createOrImportWallet/addWallet call sites while preserving existing
temporary-manager cleanup.

SwiftDashSDKWalletWiper teardown flow so it cannot block indefinitely when
startup work stalls. Coordinate the timeout with
SwiftDashSDKWalletRuntime.handleWalletWiped and fullReset: do not report the
wipe as complete or allow a new wallet to proceed until runtime teardown has
finished, even if the wait deadline expires; preserve the existing main-thread
deadlock avoidance behavior.

WalletLifecycleOverlayBridge, WalletLifecycleOverlayViewModel, and

update any required references or imports.

Reviewed this. The design is careful and the comments are honest about their own trade-offs. One cross-repo problem blocks the merge outright, and one design gap is worth fixing before it lands.

platform v4.2-dev's bea4122858 turned PlatformWalletManager .estimateShieldedFee from a static func into an instance method computed at the manager's network-tracked platform version. Migrate all call sites to the live host manager so the app compiles against v4.2-dev at or past that commit (prerequisite for consuming the merged #4469 shutdown API).

Await native SDK teardown off the main thread, serialize managed network switches behind an app-wide transition overlay, and move shielded transaction snapshot reads to a private SwiftData context with timing telemetry.
- WalletLifecycleTransitionState: one presentational phase machine with a MainActor-atomic admission gate (tryBegin/advance/finish/fail) for interactive operations; generalizes NetworkTransitionState in place - WalletLifecycleOverlayPresenter/-View: the single dedicated-UIWindow overlay now covers network switches, wallet switches, per-wallet removal and full wipes; per-operation failure cards (blocking Retry for network, Retry + Switch Back for wallet switch, dismissable OK for removal) - WalletsViewModel.gatedSwitchWallet: one gated switch shared by the row switch, post-add switch, pre-remove auto-switch and the overlay card's Retry/Switch Back; the remove flow advances Switching to Removing without dropping the window, and failures surface in the overlay (the DASHPAY tab rebuild destroys the Wallets screen mid-flow, which previously made removal failures silent); the screen-local ZStack overlay is gone - wipe contract: performWipe now blocks the wipe executor's queue until the runtime's fullReset completes, so waitForPendingWipe means "data wiped AND runtime torn down" - wipe HUDs hold to the real end and a wallet created right after can no longer race a still-queued reset - Obj-C wipe flows (root Delete All, phrase-authorized recover wipe) render in the same overlay via DWWalletLifecycleOverlayBridge; their UIKit failure alerts stay (DWRecoverViewController.m also carries a pre-existing clang-format whitespace realignment) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- beginWiping now returns the admission-gate verdict and both Obj-C wipe flows refuse to start when another lifecycle operation is in flight (a concurrent wipe would mutate wallet state under a switch's teardown) - finishWiping runs before the weakSelf guard in both wipe completions, so the wiping phase can never outlive the wiper barrier when the initiating controller is gone - the DASHPAY tab rebuild is skipped while a wipe is in flight: the wallet-removed notification fires mid-wipe and rebuilding would deallocate the recover flow awaiting the barrier - losing both the overlay dismissal and the transition to onboarding - a wallet-switch Retry starting from failedWalletSwitch carries the saved previousId forward instead of re-sampling the host (which is empty or fallback-bound after a failure), so Switch Back survives repeated failed retries Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- managerForStoredWalletOperation shuts the detached manager down before rethrowing a loadFromPersistor failure (async ripple to managerForWipe callers) instead of leaking its native teardown to the deinit fallback - the wipe's runtime-teardown wait is bounded (180 s): on expiry the wipe reports failure - never success while fullReset is unfinished - and the queued teardown keeps running in the background - WalletLifecycleTransitionState and the overlay quartet (presenter, Obj-C bridge, view model, card view) move to their own files per the one-file-one-responsibility guideline; no behavior change Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Addresses romchornyi's review of the lifecycle overlay: - failedNetworkSwitch now carries `from` and its card offers Switch Back toward the network that was active when the switch began (preserved across repeated failed retries, like the wallet card's previousId) - a wipe is admitted from EVERY failure phase, so Settings -> Reset Wallet stays reachable and a persistently failing switch can no longer wall the user off behind the overlay - the Delete All dispatch_after body releases the wiping gate when the root controller is gone, instead of leaking `.wiping` forever - MainTabbarController defers (pendingDashPayTabReconfiguration) instead of dropping the rebuild during a wipe, so a FAILED wipe still gets its reconfiguration - performWipe's main-thread branch reports failure like the timeout path instead of claiming "torn down" for a merely-queued teardown - advance(to:) hard-rejects an idle transition in Release rather than relying on a debug-only assert - both Obj-C wipe entry points alert on a rejected admission instead of silently swallowing a confirmed destructive action - WalletLifecycleTransitionStateTests: compile-ready table test pinning the admission matrix (repo test-target posture: unrunnable until the target is repaired) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Supersedes #1054 and carries its two commits unchanged — the review there grew the scope from a network-switch overlay into unifying every wallet-lifecycle loader, so this single PR replaces the stacked pair.
Two problems on top of the original freeze fix:
waitForPendingWipereported completion when wallet data was deleted while the runtime teardown was merely enqueued — wipe HUDs dropped early, and a wallet created right after could race the still-queued reset.Platform dependency: dashpay/platform#4469 is now MERGED — this PR requires platform
v4.2-devat or past1e26927c61(the #4469 merge, whose ancestor #4470 changed theestimateShieldedFeeAPI). Based on #1063, which adapts the app to that API; merge #1063 first.What was done?
WalletLifecycleTransitionState(own file): one presentational phase machine (network switch, wallet switch, removal, wipe) with a MainActor-atomic admission gate for interactive operations. A wipe is admitted from EVERY failure phase, keeping the reset route as the universal escape hatch. Admission matrix pinned by a compile-ready table test (WalletLifecycleTransitionStateTests; repo test target is temporarily broken).WalletLifecycleOverlay(own file): the dedicated-UIWindow presenter, Obj-C bridge, view model and per-phase cards. Failure cards: blocking Retry + Switch Back for network switches (failedNetworkSwitchcarriesfrom, preserved across repeated failed retries); blocking Retry + Switch Back for wallet switches (previousIdpreserved likewise); dismissable OK for removal failures.WalletsViewModel.gatedSwitchWallet: one gated wrapper shared by the row switch, the post-add switch, the pre-remove auto-switch, and the overlay card's actions; active-wallet removal advances Switching → Removing without dropping the window.performWipeblocks the wipe executor's queue until the runtime'sfullResetcompletes (bounded at 180 s — on expiry it reports failure, never success, while the queued teardown finishes in the background), sowaitForPendingWipemeans "data wiped AND runtime torn down".DWWalletLifecycleOverlayBridge: rejected admission refuses to start a concurrent wipe and says so (alert), every gate acquisition is paired with a release on all paths, and the DASHPAY tab rebuild is deferred (not dropped) while a wipe is in flight.loadFromPersistor().How Has This Been Tested?
v4.2-dev@1e26927c61(rebuilt FFI, both slices): BUILD SUCCEEDED — for this branch and fix(wallet): adopt instance estimateShieldedFee from platform #4470 #1063 standalone.Breaking Changes
