Can't pass the first step of this task

I tried numerous variants of code that worked perfectly in Xcode and still have no idea what I did wrong.

NSString *username = self.usernameField.text;
NSString *password = self.passwordField.text;

Not working.

NSString *username = [self.usernameField.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
NSString *password = [self.passwordField.text stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];

Still says I need to set both properties.

Did I miss something or it's site malfunction?

you need to set both properties. username and password are both string properties of the controller. you need to access them using self.username and self.password. You are currently creating 2 new variables username and password which is why your answer is incorrect

Oh, I get it, thanks a lot. But why view controller need that properties anyway? Isn't local variables simpler? Program hardly will call this properties out of signup view.

yes thats true, thats just the way the challenge is designed. It says that username and password are properties, so you must treat them as such
