Question ViewController upgrade from SFSafariViewController to ASWebAuthenticationSessionin in Obj C

Hey all,
I am trying to get to work AppAuth plugin for Unity3D and upgrade this Unity project from SFSafariViewController to ASWebAuthenticationSession.

The iOS SafariView.mm plugin where I'd need to make this change in the UIViewController to launch the browser needs to be in objc in Unity. I can't code in objc. Can someone please recommend what change I need to make to the this code please.

Code (CSharp):

1. #import <SafariServices/SafariServices.h>
2.  
3. extern UIViewController * UnityGetGLViewController();
4.  
5. extern "C"
6. {
7.   void launchUrl(const char * url)
8.   {
9.     // Get the instance of ViewController that Unity is displaying now
10.     UIViewController * uvc = UnityGetGLViewController();
11.     // Generate an NSURL object based on the C string passed from C#
12.     NSURL * URL = [NSURL URLWithString: [[NSString alloc] initWithUTF8String:url]];
13.     // Create an SFSafariViewController object from the generated URL
14.     SFSafariViewController * sfvc = [[SFSafariViewController alloc] initWithURL:URL];
15.     //Start the generated SFSafariViewController object
16.     [uvc presentViewController:sfvc animated:YES completion:nil];
17. }
18.  
19. void dismiss()
20. {
21.    UIViewController * uvc = UnityGetGLViewController();
22.    [uvc dismissViewControllerAnimated:YES completion:nil];
23. }
24. }

Thanks for your help!

 

You can use this code to open a browser. You can set up a deep link and handle the redirect in the Unity code.
