It looks like you are using an older version of React Native. Please update to the latest release, v0.57 and verify if the issue still exists.

The "⏪Old Version" label will be removed automatically once you edit your original post with the results of running react-native info on a project using the latest release.

Still exist in new version

[ericlewis]

@MuhammadUzair new Date('12-30-1980') isn't a valid date, so it returns undefined. If you would like to parse dates like this, I would suggest checking out moment. It works in debug mode because the JSC is different.

[MuhammadUzair]

@ericlewis For the moment what date format is required for DatePickerIOS Date Props (like DD/MM/YYYY)?

[MuhammadUzair]

Thanks @ericlewis .I Fixed this issue by change the date format in YYY-MM-DD .
