UIDocumentPicker can not display Browse at iOS 11

I wrote a program of UIDocumentPicker.
However, if I tap "Browse" on the iOS 11 simulator, loading continues to be displayed and could not be displayed.
What kind of response is necessary?

class ViewController: UIViewController, UIDocumentPickerDelegate {
    let UTIs:[String] = ["public.data"]
    // Save to this application from iCloud
    @IBAction func importDocumentPicker(_ sender: Any) {
        let importPicker = UIDocumentPickerViewController(documentTypes: self.UTIs, in: .import)
        importPicker.delegate = self
        present(importPicker, animated: true, completion: nil)
    }
}

Solution

  • By the looks of it, this is a simulator-only issue. (iOS 11.0 simulator) UIDocumentPicker works ok on devices.

    If anyone encounters this problem, just test on a real device.
