100 iOS Interview Questions (AI-Era)
If you've been preparing for iOS interviews, you've probably noticed something: most resources still teach you how to answer questions from 5–6 years ago. But interviews today are different. You're not just evaluated on what you know. You're evaluated on how you think, how you debug, and how you make decisions.
And with AI tools becoming part of daily development, interviewers are also trying to understand:
- Do you actually understand your code?
- Can you debug something you didn't fully write?
- Can you make the right trade-offs?
This list is based on patterns I've seen across real interviews, real projects, and how expectations have shifted recently. No fluff. No textbook questions. Just the kind of questions that actually come up.
