I am trying to change my Bundle-ID & SKU but i came to know that its not possible.
So i decided to delete this app and create the new one with appropriate naming, still i didn't submit anything to itunes.
But there is no option for deleting the submission
This is my 1st experience with itunes connect. When i created my 1st project, i gave random Bundle-ID & SKU, now my app is ready and i realised that it should be something else.
Any help will be great.
We are in 2019 and Apple finally (!) added a possibility to delete an app in "Prepare for Submission" state which was not previously accepted in the App Store at all (for example if you added a test app only for Testflight).
Now you can simply go to "App information" section and at the bottom you will see "Remove App" option which removes the entire application.
Also Apple's website with help: https://help.apple.com/app-store-connect/#/dev28d17ed35 was updated and now it confirms that you can remove apps in "Prepare for Submission" state:
To remove an app from your main view in My Apps, it must be first removed from the App Store and any associated in-app purchases must be removed from sale.
Additionally, you can only remove apps if all versions of that app are in one of the following states:
- Prepare for Submission
- Invalid Binary
- Developer Rejected
- Rejected
- Metadata Rejected
- Developer Removed from Sale
- Removed from Sale
Apps can’t be removed if they are part of a Game Center group, in an app bundle, currently available on the App Store, associated with in-app purchases available for sale, or if they're being actively transferred to another account.
If the app is part of a Game Center group or app bundle and hasn't been approved yet, it must be removed from the group or bundle before it can be removed from your main view in My Apps. App bundles and approved apps that are part of a Game Center group cannot be removed.
There is no way to delete an app in that state, according to the iTunes Connect Developer Guide.
Apps that have not been approved yet can’t be deleted
The only thing we can do for now is to change the name and bundle ID until Apple changes its mind.
Edit: Seems that Apple finally made this possible according to Leszek Szary's answer here
As of Year 2017, everything is still the same.. what a shame
This rule is so counter-intuitive especially for people who plan to test the app with testflight like us..
I don't know if this is gonna work. But we will prepare two apple accounts, one for testing and just name the SKU and etc whatever works. The other one is the official account use to submit app to app store..
Hope it will get fixed soon.
I saw many people experiencing this issue. The only way update version is to contact apple team. Here is it how I did.

Write your issue properly with your apple id. You will get the option to change version once they review your issue.
It took me only one day to get their reply. You will get email like this from apple team.
I also got the version ID wrong for an update and then there was no way to change it.
I think the best way is to update the build numbering. go to project and under identity section increment the build number.
for me it was
Version : 1.4.3
Build :0.4
I changed it to
Version : 1.4.3
Build :0.5
I didn't find any other solution to my problem. Hope this helps someone
