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)

从表面上看，这是一个模拟器问题。 (iOS 11.0 模拟器) UIDocumentPicker 在设备上工作正常。

如果有人遇到此问题，请在真实设备上进行测试。
