I’m trying to use the new consuming keyword while attempting to rewrite our codebase to Swift 6:

1.  Apple Swift version 6.0.2 (swiftlang-6.0.2.1.2 clang-1600.0.26.4)
2.  Compiling with the current language version
3.  While evaluating request ExecuteSILPipelineRequest(Run pipelines { Mandatory Diagnostic Passes + Enabling Optimization Passes } on SIL for PushNotificationServiceExtension)
4.  While running pass #615 SILFunctionTransform "MoveOnlyTypeEliminator" on SILFunction "@$s32PushNotificationServiceExtension0bC0C011setupCustomB4Task33_8D4DCFB31FB634FB0683A4519898C954LL8imageUrl18bestAttemptContent14contentHandlery10Foundation3URLV_So09UNMutablebR0CnySo014UNNotificationR0CcntFyyYaKcfU_".

Command SwiftCompile failed with a nonzero exit code

The code:

  private func downloadImageTask(
    imageUrl: URL,
    bestAttemptContent: consuming UNMutableNotificationContent,
    contentHandler: consuming @escaping (UNNotificationContent) -> Void
  ) {
    self.setupImageTask = Task {
      let (location, _) = try await URLSession.shared.download(from: imageUrl)
      let desiredLocation = URL(fileURLWithPath: "(location.path)(imageUrl.lastPathComponent)")
      
        try FileManager.default.moveItem(at: location, to: desiredLocation)
        let attachment = try UNNotificationAttachment(identifier: imageUrl.absoluteString, url: desiredLocation, options: nil)
      bestAttemptContent.attachments = [attachment]
      contentHandler(bestAttemptContent)
    }
  }

Any clue?
