UITextView in custom inputaccessoryView not resigning first responder status

I have a chat application that implements a floating text input field (similar to the iOS Messages app) as the inputAccessoryView of my ChatViewController (see Apple's documentation).

class ChatViewController: UIViewController {      override var inputAccessoryView: UIView? {        return chatInputView     }      override var canBecomeFirstResponder: Bool {         return true     }     ... 

My ChatViewController has a ChatTableViewController child view controller, which has cells containing UITextFields whose text content is editable. The issue I'm running into is that when the user taps on a cell's UITextField, the inputAccessoryView's UITextView refuses to resign first responder status, which prevents the content in the UITableViewCell from being edited. The following warning is logged in the console:

 First responder warning: '<UITextView: 0x7fc041041c00;   frame = ...' rejected resignFirstResponder when being removed from hierarchy 

I've tried calling resignFirstResponder and endEditing on the UIInputView and UITextView directly with no success. I don't want the ChatViewController to resign first responder status as that would cause the inputAccessoryView to disappear.

Could you please check the following:

If UITextView is removed from super view:

• Is the UITextView being removed from the view hierarchy ?
• If so could you resignFirstResponder before removing it from the super view.

If UITextView subclass is being used:

• Are you using a subclass of UITextView, if so have you implemented canResignFirstResponder to return false.
• Could you try returning true instead.
