Deleting content on iPhone and iPad

This might seem like a dumb question but is there no way to delete games from the iOS retroarch from inside the app? i am on a not jailbroken iPad and i can’t delete games. evertyign i see says to use a file browser but that doesn’t work on nonjailbroken iPads. i want to delete games when i run out of space with out having to connect my iPad to a computer or be jailbroken.

not possible to delete files or games on a not jailbroken iPad?

No, you have to do it with a computer.
