How do you do this? What if the model already exists?

This did not answer the question and the advice isn't close to what is being asked. Words in the icon versus words under the icon, a.k.a. the display name. The OP is asking if the official name of the app as written in App Store Connect is the same as the display name after the app has been installed and the icon becomes visible on the home screen/desktop. The answer is: yes, duplicates are fine in the display name, but the app name must be unique.

I love you. Thank you for this solution. It finally works.

where do you put this code? what is the context?
