How to enable a button when all textfield is filled

Question

Initially button.isHidden = true, however, I would like to set the button.isHidden = false, when all textfields are filled. Where should I put the If-Else condition in, most probably not in viewDidLoad, please advise.

Please provide what you tried, and most importantly, your code. — f_qi, Mar 29 '17 at 15:49

You might want to take a look at this post UITextField text change event and then in textFieldDidChange function you should check texts of each textfield
