How to Add ROMs to Delta via AirDrop
The fastest way to get a ROM onto your iPhone — no cloud upload, no cable, just AirDrop it straight into Delta.
Overview
AirDrop transfers files device-to-device over Wi-Fi and Bluetooth, which makes it the fastest option when a ROM is already sitting on a Mac or another iPhone or iPad — there's no upload to a cloud service and no waiting on an internet connection at all.
iOS routes AirDropped files to a share sheet, and if Delta is installed, it can show up directly as an "Open in Delta" target — the file goes straight into the app's library without a separate Files-app detour in the best case.
Both devices need AirDrop visibility turned on before the transfer starts, either "Contacts Only" for people already in your address book or "Everyone for 10 Minutes" for a device that isn't.

Good to Know
Turn AirDrop visibility back to "Receiving Off" after transferring, especially if you switched it to "Everyone" mode for the transfer.
Because AirDrop works over Wi-Fi Direct, it doesn't need an active internet connection, which makes it useful when Drive or iCloud sync is slow or unavailable.
Sending a whole folder of ROMs at once works fine too — Delta will let you import them one at a time from Files once they land.
