Yes native Swift, I was learning Swift/SwiftUI as well while building it, the source code is here: https://github.com/nostur-com/nostur-ios-public

@Fabian Great write-up on MISSION.md "We don’t need to store our data on random relays, and hope our contact list doesn’t get lost, or leak metadata to the public. We can store everything on our device". This is EXACTLY what I was thiking for my app. Have a small database like SQLite on the device and load that first. Then query relays for updates. Have a standard import/export format for Nostr that different clients can use. Have this format be an official NIP . This format could be as simple as a linear array of EVENTS in JSON format. This is what I use in my dev database, as you can see a "database" can be as simple as 100 lines of code, with functions to read(), save(), append() and request(), (from relays) @melvincarvalho @fiatjaf @Will @jack https://github.com/pedro-vicente/nostr_client_relay/blob/main/src/database.cc

yep I’m using sqlite too now, through CoreData. Seems nostrdb will be great too when ready but for me the database is not the performance bottleneck right now
Also looking forward to try nostrdb, I’m doing (slowly doing) a Windows / Cmake port. It seems the latest benchmarks are very good nostr:npub1xtscya34g58tk0z605fvr788k263gsu6cy9x0mhnm87echrgufzsevkk5s In my case I have no real DB, and the bottleneck is the time to query relays. For 1 relay only it takes about 4 seconds to get a feed of about 20 follows. But I guess there is not much room here for improvement because of the decentralized nature. So, the idea of having all locally cached in DB, and query asynchronously in background, for example https://github.com/pedro-vicente/nostrdb
