Is there any way to hide suggestions list above keyboard? I couldn't find any solution in documentation.
Yes there is. You have to disable autocorrection on the text field/text/any other class that conforms to the UITextInputTraits protocol, which can be done through the autocorrectionType property.
textField.autocorrectionType = .no
Additionally, if you're interested, the following are the only UIKeyboardTypes that don't have suggestions by default.
