Upgrading to ios 13 creating immense memory issues

Question

I already have an app up and running on the appstore. Now, something really weird is happening. I have 2 targets, DEV and PROD. Obviously PROD is on the Appstore and and both were running completely fine on my phone until I updated to ios 13.

The issue started taking place in the Beta App(DEV) and the whole app behaves choppy, while the PROD app is working completely fine. This is some weird behavior I have noticed recently. Upon using the beta version, the Phone starts heating up, the app lags, memory issues etc. On the contrary, the PROD app is working completely fine.

What supposively could be the issue? I am loosing my mind on this. Would love any help. Please let me know if any more information is required. I'll be prompt.

Answer 1

There is no such difference between DEV and PROD version only difference in configuration, But the main difference release version is well optimized and do not contain extra information like complete symbolic debug information is emitted to help while debugging application and code optimization is not taken into account. So please check optimzation level in xcode for debug and also check where your app is consuming more energy and cpu usage using instrument.

Hope this will help.
