FAQ

Q: How often should I deploy? A: Beta releases weekly, production monthly. Adjust based on your needs and user feedback.

Q: What's the minimum test coverage? A: Aim for 85% overall, 100% for critical paths, especially in analytics and payment processing.

Q: How do I handle hotfixes? A: Create hotfix branch from release tag, fix issue, increment patch version, deploy immediately.

Q: Can I automate everything? A: Almost everything, but maintain human checkpoints for production releases and major updates.

Q: What if I don't have iOS device? A: Use physical iOS device for final testing or remote testing services.
