ios - How can I test an authentication challenge? -

dear fellow citizens of earth.

i'm requesting real life example can test authentication challenge code snippet found below. if it's not possible appreciate suggestions on can validate it.

i have feeling code working:

- (void)webview:(wkwebview *)webview didreceiveauthenticationchallenge:(nsurlauthenticationchallenge *)challenge completionhandler:(void (^)(nsurlsessionauthchallengedisposition, nsurlcredential * _nullable))completionhandler {     nsstring *host = webview.url.host;      nsstring *authenticationmethod = [[challenge protectionspace] authenticationmethod];      if ([authenticationmethod isequaltostring:nsurlauthenticationmethoddefault]         || [authenticationmethod isequaltostring:nsurlauthenticationmethodhttpbasic]         || [authenticationmethod isequaltostring:nsurlauthenticationmethodhttpdigest]) {          nsstring *title = @"authentication challenge";          nsstring *message = [nsstring stringwithformat:@"%@ requires username , password.", host];          uialertcontroller *alertcontroller = [uialertcontroller alertcontrollerwithtitle:title message:message preferredstyle:uialertcontrollerstylealert];          [alertcontroller addtextfieldwithconfigurationhandler:^(uitextfield *textfield) {              textfield.placeholder = @"username";         }];          [alertcontroller addtextfieldwithconfigurationhandler:^(uitextfield *textfield) {              textfield.placeholder = @"password";              textfield.securetextentry = yes;         }];          [alertcontroller addaction:[uialertaction actionwithtitle:@"authenticate" style:uialertactionstyledefault handler:^(uialertaction *action) {              nsstring *username = ((uitextfield *)alertcontroller.textfields[0]).text;              nsstring *password = ((uitextfield *)alertcontroller.textfields[1]).text;              nsurlcredential *credential = [[nsurlcredential alloc] initwithuser:username password:password persistence:nsurlcredentialpersistencenone];              completionhandler(nsurlsessionauthchallengeusecredential, credential);          }]];          [alertcontroller addaction:[uialertaction actionwithtitle:@"cancel" style:uialertactionstylecancel handler:^(uialertaction *action) {              completionhandler(nsurlsessionauthchallengecancelauthenticationchallenge, nil);         }]];          [_delegate webview:self didreceiveauthenticationchallengewithalertcontroller:alertcontroller];     }     else if ([authenticationmethod isequaltostring:nsurlauthenticationmethodservertrust]) {          completionhandler(nsurlsessionauthchallengeperformdefaulthandling, nil);     }     else {          completionhandler(nsurlsessionauthchallengecancelauthenticationchallenge, nil);     } } 

love , peace all.

older question: how can implement authentication challenge using wkwebview?

usually have set specific breakpoints in code , manipulate variables in debugger console statements expr varname=@"test" test code this.

the interesting part here how trigger call webview:didreceiveauthenticationchallenge:

1. use http testing service httpbin - e.g. this basic auth test
2. write simple webserver python, ruby etc. , test against it
3. configure osx-builtin apache httpd use basic auth access, test ios simulator against localhost. here's simple tutorial on how configure server. sure check comments, steps outdated (e.g. conf file located @ /etc/apache2/httpd.conf)
