ASWebAuthenticationSession and autofill Login/Password

Hello,

I have an app that views a web page. This web page requires login. So, I decided to use ASWebAuthenticationSession to autofill web page with credentials. Needless to say it is not working. Here is my code;

#import "ViewController.h"
#import 

@interface ViewController ()
@property (strong) ASWebAuthenticationSession *session;
@end

@implementation ViewController
@synthesize session;

- (void)viewDidLoad {
    [super viewDidLoad];
}

- (IBAction)loginBtnClicked:(id)sender {
    NSURL *destinationUrl = [NSURL URLWithString:@"https://***.yyy.edu"];
    NSString *callbackUrlScheme = @"https://***.yyy.edu/Pages/main.aspx";
    session = [[ASWebAuthenticationSession alloc] 
         initWithURL:destinationUrl 
         callbackURLScheme:callbackUrlScheme 
         completionHandler:^(NSURL * _Nullable callbackURL, NSError * _Nullable error) {
             if (error != nil && error.code == 1){
                 [self.session cancel];
             } else {
                 printf("Error: %s", error.localizedDescription.UTF8String);
             }
    }];
   
    BOOL started = [session start];
    printf("Started? %s", started ? "TRUE":"FALSE");
}
@end
