As you all know, Apple changed how Xcode works such that you can\'t ever create an app with a previously used app ID, even if you\'re just writing test apps to use locally.
It is type of limits of free developer accounts, but we could figure out a solution for that too :
1- Navigate to the project of any previous application that have been installed on the same device has the problem with .
2- Open Build Settings tab for the app project in Xcode .
3- Search for Bundle ID and copy it .
4- Open up your current app that has the problem and navigate to the same place > Paste and Replace the current Bundle ID with the old one.
5- Run the app.
