I have finished the chapter. as a result the button Done becomes disabled each time I press the Clear button but only for the first three times. When I push Clear button for the forth time, the textField stays empty and the Done is enabled.
After entering one text and pushing Done, and then clearing 4 times and pushing Done again, my print message in the console looks like that:
Contents of the text field: Nbn
Contents of the text field:
Any advice would be appreciated.
