Swift:

UIBarButtonItem.appearance().setTitleTextAttributes([NSAttributedString.Key.font: UIFont(name: "Poppins-Regular", size: 16)!,NSAttributedString.Key.foregroundColor:.red], for: .normal)

Objective-C:

[[UIBarButtonItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                          [UIColor colorWithRed:245.0/255.0 green:245.0/255.0 blue:245.0/255.0 alpha:1.0], NSForegroundColorAttributeName,
                                                          shadow, NSShadowAttributeName,
                                                          [UIFont fontWithName:@"Futura-Medium" size:15.0f], NSFontAttributeName, nil] forState:UIControlStateNormal];
