To delete a contact on an iPhone:
- Open the “Contacts” app and find the contact you want to delete.
- Tap the contact to open it.
- Scroll to the bottom of the contact page and tap “Delete Contact.”
- Confirm that you want to delete the contact by tapping “Delete Contact” again.
Alternatively, you can delete a contact by swiping left on the contact in the “Contacts” list and tapping “Delete.”
Please note that deleting a contact will permanently remove it from your iPhone. If you want to keep a copy of the contact, you can export it to another app or service before deleting it.
