Compile Errors

[reyamir]

I've tried to use Nostr SDK in my SwiftUI app, but when compile, I've got a lot of errors

My simple code:

Init

import SwiftUI
import SwiftData
import NostrSDK

@Observable
class Nostr {
  var client: Client = ClientBuilder.init().database(database: try! NostrDatabase.lmdb(path: "nostr.db")).build();
}

@main
struct SampleApp: App {
  @State private var nostr = Nostr()
	
  var body: some Scene {
    WindowGroup {
      ContentView().environment(nostr)
    }
  }
}

Just get the nostr state

struct ContentView: View {
  @Environment(Nostr.self) private var nostr

  var body: some View {
    NavigationSplitView {
      List {
      }
      .navigationSplitViewColumnWidth(min: 180, ideal: 200)
      } detail: {
        Text("Select an item")
      }
  }
}

Maybe related to this issue? mozilla/uniffi-rs#2108

I don't think, because I'm not using nested errors in bindings.

I opened a PR with a possible fix here: rust-nostr/nostr#633
I haven't a mac so I can't try it, are you able to test it? You can follow these steps for compilation: https://github.com/rust-nostr/nostr/tree/master/bindings/nostr-sdk-ffi#swift

Later, instead of use the package from the git repo, point it to /path/to/nostr/bindings/nostr-sdk-ffi/swift dir.

If it works, I'll publish the fix.

I still got same error

[yukibtc]

I think the issue should be fixed. At least, the previous error is no longer returned in the CI, now it return linking errors when running swift test, but I'm not sure if this is related to the GitHub Actions or is effectively an issue in the Swift Package (I not found a way to make the swift test works).

Can you let me know if now works? The fix-swift branch in https://github.com/rust-nostr/nostr repo.

Hi, this issue is fixed. I will add Example for Nostr Swift soon

[reyamir]

I've got a other error which say "UniFFI API checksum mismatch", but I not sure it related to your fixes or not. I've tried rebuild project but still not work.

Maybe I found the issue: the uniffi_checksum_derive crate was at another version (0.28.2 instead of 0.28.0, selected automatically). I'll publish a fix soon.

I pushed the fix. The CI still fail, but hope the "UniFFI API checksum mismatch" error is fixed.

I've finally fixed all the CI issues. I can now see the "Uniffi API checksum mismatch" error. It's weird that this happen only in Swift and not in Python or Kotlin. I opened an issue on the UniFFI repo: mozilla/uniffi-rs#2321
