Indicator does not close when AlertController is called while RefreshIndicator is displayed.

- Xcode 13.3.1
- Swift 5.6
- iOS 15

Hello.

I found a mysterious spec about RefreshController and AlertController.

see the code.

  collectionView.refreshControl = refreshControl
  refreshControl.addTarget(self, action: #selector(refreshAction(_:)), for: .valueChanged)
}

@objc func refreshAction(_ selector: UIRefreshControl) {
  Task { @MainActor [weak self] in
  guard let self = self else { return }
    do {
      let response = try await api.getData()
      //
      self.refreshControl.endRefreshing()
    } catch {
      self.refreshControl.endRefreshing() // could't end refresh indicator.
      let alert = UIAlertController(title: "Error", message: "", preferredStyle: .alert)
      alert.addAction(UIAlertAction(title: "OK", style: .default))
      self.present(alert, animated: true, completion: nil)
    }
  }
}

Why I could't handle endRefreshing when I called AlertController?

I have solution this problem for another way. I would like to solve this problem without using the alert closure if possible.

@objc func refreshAction(_ selector: UIRefreshControl) {
  Task { @MainActor [weak self] in
  guard let self = self else { return }
    do {
      let response = try await api.getData()
      //
      self.refreshControl.endRefreshing()
    } catch {
      let alert = UIAlertController(title: "Error", message: "", preferredStyle: .alert)
      alert.addAction(UIAlertAction(title: "OK", style: .default, handler: { _ in
        self.refreshControl.endRefreshing()
      }))
      self.present(alert, animated: true, completion: nil)
    }
  }
}
