SWIFT Profile-loading concurrency scenario Candidate responding

Question 08 Interview stage

Advanced Difficulty

Concurrency Primary skill

Open response Answer format

A profile screen sometimes displays the previous user's data after rapid account switching.

The candidate must identify stale asynchronous work, cancel or isolate previous tasks, protect main-thread state updates, handle loading and errors, and explain how the implementation should be tested.

func loadProfile() {
  Task {
    isLoading = true
    profile = try? await service.fetch(id)
    isLoading = false
  }
}

TASK

Identify overlapping asynchronous tasks

A previous request may complete after the selected account changes and overwrite current state.

Diagnose

STOP

Add cancellation or request identity

Store the task, cancel it when inputs change, or validate the active account before applying results.

Resolve

MAIN

Protect UI state updates

Use MainActor for observable interface state and keep loading, error, and success transitions consistent.

Improve

TEST

Verify lifecycle and regression behaviour

Test rapid switching, delayed responses, cancellation, view dismissal, failures, retries, and deallocation.

Verify

Review how the candidate investigates lifecycle and concurrency.

Evaluate task ownership, cancellation, actor isolation, observable state, memory management, loading and error transitions, edge cases, testability, user experience, and communication clarity.
