iOS 14.3 UITextField leak?

Question

Why is the UIKeyboard implementation still holding a reference to this UITextField, thus keeping it from being deallocated?

The memory debugger shows:

UIKeyboardImpl -> UIKBAutofillController -> NSMutableDictionary -> NSMutable...(Storage) -> UITextField

Any idea what's going on there?

Answer 1

It seems to disappear if I set:

Code Block textField.autocorrectionType = UITextAutocorrectionType.no

I tried that because of the UIKBautofillController pointing to the field in the memory debugger.

It helps if keyboardType = .default, but doesn't for numberPad, for example - UIKBautofillController retains text field again.

In my case it was phone number field, so I set textContentType = nil and tried to prevent heuristics to detect content type - removed placeholder, renamed outlet and field class; still no luck - autofill controller was here.

I cannot offer any help, but I have the same issue. I noticed that it appears when I switch the view while the cursor is still in the text field. I tried adding resignFirstResponder in different ways, it did not help.

If anyone (else) is coming across this issue with their custom UITextInput control. The following work around will work (assuming you don't need autocorrect):

var autocorrectionType: UITextAutocorrectionType {
    get { .no }
    set { fatalError() }
}
