Swift interview questions
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.
Use the keyword as a starting point, then judge the work by whether it solves the reader's actual problem. A strong answer names the context, the decision, the closest alternative, the failure mode and the evidence that would change the recommendation.
