my app is available on app store. i new to release an update but with older version is this possible? please guide me
can i upload new build with older version at app store?
I believe you will need to rebuild the older version with a higher version number than the live release and re-upload to App Store Connect. App Store Connect will not allow you to upload a build with a lower version number than the current release.
You can see in App Store Connect - Create a new version, step 3 requires incrementing the version number.
No, you must increment the version for an update on AppStore
