Can I transfer files to/from an iPhone over wifi without knowing IP addresses?

I am a new iPhone owner. Previously, I installed [KDE Connect](https://community.kde.org/KDEConnect) on both my GNU/Linux laptop and Android device. This allowed me to pair the devices on my local network without knowing their local IP addresses, and transfer files between them without a cable. It appears that there is no Connect-compatible client on the Apple App Store (see footnote 1). I have found instructions for [pairing and transferring files to/from an iPhone with a cable](https://www.dedoimedo.com/computers/linux-iphone-6.html) . I don't want to rely on an internet connection. How can I: * pair a GNU/Linux system with an iPhone on a local wifi network * without knowing their respective IP addresses * and then transfer files between them? Installing packages/apps on either device is acceptable, but the apps must be libre licensed (even on the Apple App Store). ---- Footnote 1: > There was some development of a KDE Connect client app for iOS in 2014... but due to our experience and various technical and organizational factors it's unlikely that we will have official iOS support anytime soon.
