Hello friends.
I’ve been looking for the solution to a problem with firebase for days.
When I call the Singin function in firebase, during the IF Not Error, it executes both options (if & else) that results in an alert in the else section, Curiously even though I change the title and the alert message is not change The correct part is also executed (if no error) this sends to the next screen, where everything works perfectly with firebase (read and write) but the alert still appears on the new screen,
I have noticed that if I delete the block of the alert it does not seem and that if I print the text of the error of the singin it indicates: Undefined.
Thanks to those who can help me
