"The App Name you entered has already been used" even though I just created the app
I am trying to create my app on iTunes Connect, so I can add my game center features. When I reach the screen where I fill in the default language, app name, sku number, and bundle id, I receive an error message:
The App Name you entered has already been used.
Does this mean someone else has used this app id? I couldn't find the an app with this name on the iTunes Store anywhere.
I just started creating the app on iTunes Connect, so I definitely didn't use it.
Is there some way to verify that this is not a bug, and someone else has chosen the name?
Answer
If you created an entry for the first App in iTunesConnect, even if it was never submitted or uploaded, then that name is locked to that iTunesConnect App permanently. That means if another user have choose same name already but still not upload and release app than you will not able to find on itunes store.
See Apple app store tips
The name you select for your app is perhaps one of the most important aspects to marketing your app and can distinguish your app on the App Store.
If you submit an app name which is already in use within the same geography in which your app is sold, you will be prompted to enter another name.
