Senior iOS interview questions

Prepare senior iOS interview questions that test judgment across Swift, architecture and production work.

Who this is for

Senior iOS candidates who need defensible answers rather than memorized definitions.

What to cover

  • State ownership
  • Concurrency and cancellation
  • UIKit and SwiftUI migration
  • Incidents, performance and release decisions

The useful result

A bank of answers structured around context, choice, tradeoff and evidence.

A strong answer names the context, the decision, the closest alternative, the failure mode and the evidence that would change the recommendation.
