Have you encountered any difficulties deploying or operating a system in production at your previous job?

Yes, when deploying and operating iOS applications in production, difficulties often arise, such as:

• Certificate and signing profile issues — incorrect configuration can prevent the app from being uploaded to the App Store.
• Environment configuration errors — for example, incorrect API URLs or keys, causing failures.
• Memory management and leaks — problems that may manifest in production but are not noticeable during testing.
• Error handling and logging — insufficient log detail complicates diagnostics.

To address these issues, it is important to:

• Use build automation tools (Fastlane, CI/CD).
• Implement advanced monitoring (Crashlytics, Sentry).
• Conduct thorough testing on various devices and iOS versions.
• Regularly update certificates and signing profiles.
