I have my SingletonRepo in my iOS app that is a instance of the shared Kotlin module of my KMM app.

The singleton repo:

class SingletonRepo{
static var shared = FirestoreRepo()

private init() { }

static func reset() {
//shared.closeRealm()
shared = FirestoreRepo()
}

The way that I use my repo in my Swift code:

var repo = SingletonRepo.shared
repo.myMethod()


My question is should I make the singleton class as @MainActor?
While swiftching to Swift version 6 I get an error: Static property 'shared' is not concurrency-safe because it is nonisolated global shared mutable state

Should I change to MainActor or Sendable?

What solution did you go for in the end? I used an actor in a similar situation, but I think it depends on your use case.
Sharing these - helped me better understand what I needed.
• Swift 6 and singletons / @Observable and data races
• Swift Concurrency Playlist (quite long, but there are a few useful videos in there)
