NSManagedObjectContext perform: Sending value of non-Sendable type

Swift 5 How to resolve warnings:

'Sending value of non-Sendable type '() throws -> ()' risks causing data races; this is an error in the Swift 6 language mode'

for this code:

import CoreData
class Model{
  func foo()async throws {
    let ctx = NSManagedObjectContext(concurrencyType: .privateQueueConcurrencyType);
    //....
    try await ctx.perform{ // warning here
      if ctx.hasChanges {
        try ctx.save();
      }
    }
  }
}

I found a solution

If you add a @Sendable the warning will disappear

func foo()async throws {
      let ctx = NSManagedObjectContext(concurrencyType: .privateQueueConcurrencyType);
      //..
      try await ctx.perform{ @Sendable in // warning disappear
        if ctx.hasChanges {
          try ctx.save();
        }
      }
    }
