iOS Web View issue

[EvanWestermann]

Encountering issue with the iOS SFSafariViewController opening the web view for the authentication flow. iOS does not receive the auth_code or auth_token from this OAuth request. The only workaround I could get to work was to disable the webview and force iOS to open the default system browser by modifying OIDAuthorizationUICoordinatorIOS.m to just call [[UIApplication sharedApplication] openURL:requestURL]; regardless of the iOS of the device.

I'm suspicious the webview is somehow suppressing, losing, or ignoring the response from the auth server.

FIXED - Make sure your callbackURL has a trailing slash.

Example:
com.example.app://callback - FAILURE
com.example.app://callback/ - SUCCESS

In OIDAuthorizationService.m, the shouldHandleURL method will fail when attempting to continue the authorization flow if your redirectURL DOES NOT include a slash at the end. Specifically, it is the check for OIDIsEqualIncludingNil(standardizedURL.path, standardizedRedirectURL.path) that fails.

I would suggest, in the portion of the README that details how the callbackURL and custom scheme need to be defined, calling out that this is a necessary component of the url. Might save some people some trouble.
