Summary by CodeRabbit

  • Bug Fixes

    • Improved coin-control updates so they use the correct send-flow context for the selected wallet.
    • Prevented coin-control actions from proceeding when the required send-flow context cannot be resolved, reducing the risk of applying updates incorrectly.
  • Reliability

    • Improved handling of both immediate and delayed coin-control changes during send flows.

CoinControlManager now accepts an optional weak SendFlowManager dependency instead of reaching into AppManager.shared directly. CoinControlContainer injects app.sendFlowManager when creating the manager, so coin control can safely update send flow state even if the linked send flow is released before coin control closes.

📝 Walkthrough

Walkthrough

CoinControlManager now resolves SendFlowManager instances by WalletId through dependency injection. The container supplies cached managers, updates skip dispatch when resolution fails, and tests verify resolver calls.

Changes

Coin-control send-flow resolution

Layer / File(s) Summary
Injected resolver and update dispatch
ios/Cove/CoinControlManager.swift, ios/Cove/Flows/CoinControlFlow/CoinControlContainer.swift
CoinControlManager accepts a wallet-scoped resolver. Immediate and delayed updates use the resolved manager and skip dispatch when resolution returns nil. The container resolves cached managers through a weakly captured app.
Resolver behavior tests
ios/CoveTests/CoinControlManagerTests.swift
The test tracks resolver calls, waits for update resolution, and verifies an additional resolution when continuePressed() runs.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 194a2

Coin-control selections can fail to update the associated send flow when a manager is created without an explicit resolver. Require the resolver at construction before merging.

Greptile Summary

This PR gives each iOS CoinControlManager a weak reference to the send-flow instance active when it is created, replacing repeated lookups through the global AppManager.

  • Passes the current send-flow manager from CoinControlContainer.
  • Routes selection updates and the Continue action to the linked send flow.
  • Preserves wallet-level coin control when no send flow exists; the subsequent send route applies the selected UTXOs after initializing its manager.

Confidence Score: 5/5

The PR appears safe to merge, with no concrete correctness, security, or repository-rule violations identified.

The linked manager can validly be absent or released, while the selected UTXOs continue through the navigation route and are applied by the destination after its send-flow manager is initialized.

Important Files Changed

Filename Overview
ios/Cove/CoinControlManager.swift Stores the associated send-flow manager weakly and uses that specific instance for coin-control selection updates.
ios/Cove/Flows/CoinControlFlow/CoinControlContainer.swift Injects the currently active send-flow manager when constructing the route-owned coin-control manager.

Comment thread ios/Cove/Flows/CoinControlFlow/CoinControlContainer.swift Outdated
Navigation can replace the cached SendFlowManager, so a
weak stored reference goes stale. Resolve the current
app-owned instance by wallet id when continuing or
updating selection.

Comment thread ios/Cove/CoinControlManager.swift Outdated
Continue now cancels the debounced send-flow update
before resolving the manager, and sleep is injectable so
tests can prove the pending resolve does not run.
Route arguments own the selected UTXOs, so apply them when the
send flow loads instead of coupling CoinControlManager to the
send manager during selection.
