react native app works on debug mode, but not works release mode on ios

Question

I Have an app on react native. Debug mode works on ios. But Release mode not works. I tried change the optimization level but not helped. The problem that I don't see any error. Just not working some functional. And I can't debug release version of app. How to solve this problem?

As a last change we added following saga, when we remove calling this saga it works

      cancel: take(['CHANGE_PASSWORD_PASSWORD_RESET'])
    });
    //yield put( loader('hide') );
        yield put( loader('hide') );

Based on the information provided, it seems like you're loading different bundles when switching between debug and release modes.

Make sure you configured your app to use a static bundle in Release Mode.

Then your app will render the same bundle in both modes, and the behavior may be as you're expecting.

It has to be a library which is clashing with your iOS version of the app. Try removing libraries one by one and see if it works on each attempt.

A shortcut would be to check the code of the libraries you are using and see if any of the APIs which are being used by the library is deprecated or not.

I came across a similar problem and in my case, it was lottie-animation which was causing the problem. Hope you'll be able to solve it.

~~Seems like you do console.log's in your code. Since your real phone environment dosen't have console-global variable make sure you get rid of these before compiling to production release.~~

EDIT

Previous statement is not entirely true. Even tho I have myself run into edge cases where console.log will crash your app when not running in debugging mode, it seems like this is not always the case and production build would run with them in place. Either way performance increase you might achieve by removing them should be taken in consideration https://facebook.github.io/react-native/docs/performance.html#performance

react native app works on debug mode, but not works release mode on ios
