Swift actor isolation violation
Swift.*actor.*isolated.*cannot be referenced from.*nonisolated.*context
Fixes
- 1.Mark the calling function as async and use await for actor calls
- 2.Use nonisolated keyword if the property doesn't need isolation
- 3.Use MainActor.run {} to switch to appropriate actor context
