Change app name in apple store of an already released/available iOS app

I released an iOS app in the Apple App Store some weeks ago and now want to rename my app (I only want to add a space). I did not find an "edit nam开发者_开发百科e" button in iTunes Connect or a solution via google.

Can someone tell me how to rename the app? Is it enough to rename the app in Xcode to get the name to automatically updated with the next Apple approval? Or do I have to release a completely new app with the new title?

You will need to do an update to the app store. I would leave your targets and executables the same, just change the Bundle Display Name property in your info.plist to the name you want your app to show on the iphone screen. That should do the trick.

To change the displayed-name of your application as it will show on the iPhone screen ("springboard"),
edit your application's plist.

To change the displayed-name of your application in iTunes App-Store,
edit the details of the last revision you have uploaded to iTunes -
