Swift interview questions
Prepare Swift interview answers about value semantics, protocols, memory, errors and concurrency.
Who this is for
Experienced iOS engineers preparing for Swift depth rounds.
What to cover
- Value and reference semantics
- Protocols and generics
- ARC and memory
- Errors and concurrency
The useful result
Swift answers that explain behavior, tradeoffs and production consequences.
A strong answer names the context, the decision, the closest alternative, the failure mode and the evidence that would change the recommendation.
