App Publish warning

I received this warning when publishing my app and i suspect that its caused by the arm7 setting in my iOS defaults under project build settings. But i cannot seem to change it in anyway. Can anyone help please? Thank you so much.

you can ask apple if they can help with that, ios 12 is still 32 bit from what i know and going ios 13 makes it 64 bit

ok noted:) thank you Francis
