Buttons not visible in UIDocumentPickerViewController

I want to import a document into my application. I have created a Demo to import Document. A demo is working. below is the code of the Demo to open UIDocumentPickerViewController. 

-(IBAction) btnOpenClicked{
    UIDocumentPickerViewController *documentPicker = [[UIDocumentPickerViewController alloc] initWithDocumentTypes:[self allowedUTIs] inMode:UIDocumentPickerModeImport];
    documentPicker.delegate = self;

    [self presentViewController:documentPicker animated:true completion:nil];
}

-(NSArray*)allowedUTIs{
    return @[@"public.data",@"public.content",@"public.audiovisual-content",@"public.movie",@"public.audiovisual-content",@"public.video",@"public.audio",@"public.text",@"public.data",@"public.zip-archive",@"com.pkware.zip-archive",@"public.composite-content",@"public.text"];
}

The same code is implemented in my actual project. UIDocumentPickerViewController open and App is able to import file but the issue is that in the actual app I am not able to see any buttons in the header. thought there is action happen but buttons are not visible. Please check screenshot of the Demo and actual app.

For Objective C:

-> by putting this code somewhere in your application:didFinishLaunchingWithOptions:

[[UINavigationBar 
    appearanceWhenContainedInInstancesOfClasses:
      @[[UIDocumentBrowserViewController class]]] setTintColor: nil];

Your app is probably setting a global UINavigationBar tint color appearance. You can just reset the appearance for UIDocumentPickerViewController only by putting this code somewhere in your application:didFinishLaunchingWithOptions: function and the bar buttons will return to their original blue.

if #available(iOS 11.0, *) {
    UINavigationBar.appearance(whenContainedInInstancesOf: [UIDocumentBrowserViewController.self]).tintColor = nil
}
