I had uploaded an app on app store with version 1.1.0.
It was accepted and is now on sale.
Now I have made small fixes and need to submit the app again.
Will I be able to submit the app on store, if I keep the same version.
Build version is not the version that app-store uses. It's just for the purpose of developers to refer for themselves. Both values needs to be incremented for application to upload.
Bundle version is the important one and should be updated if you want to update your app in app-store. It will also be shown in app-store.
