Sounds like a great project! check out nostr:npub1reezn2ctrrg736uqj7mva9lsuwv0kr5asj4vvkwxnrwlhvxf98tsq99ty4's Monday app which is an example iOS wallet built with BDK and LDK Node. It's still in an early state but I've used it to successfully on my phone to create channels to an LN node of my choice and send payments to my Phoenix wallet and to nostr:npub1theparkprcs70dcs437ke9zzwsr6u60f8flu7rg28m30438aep9sd94dha's BTCPayServer. 🎉
