How to integrate two apps in xamarin iOS? - xamarin.ios

Question

I have two apps. One called SincApp that take a pic and should return it for caller with a status. So, a image and a string.
This app was be developed in swift.
Other called ZipZag that call SincApp and wait for your response that should show the image taked and status string in a label, developed in Xamarin.
I was configured Info.plist like this:
Info.plist
<key>LSApplicationQueriesSchemes</key>
<array>
<string>sincapp-scan</string>
</array>
<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleURLName</key>
<string>br.com.xxx.SincApp</string>
<key>CFBundleURLSchemes</key>
<array>
<string>sincapp-scan-back</string>
</array>
</dict>
</array>
<key>UIApplicationSceneManifest</key>
<dict>
<key>UIApplicationSupportsMultipleScenes</key>
<false/>
</dict>
<key>UIRequiresFullScreen</key>
<true/>
<key>CFBundleDocumentTypes</key>
<array>
<dict>
<key>CFBundleTypeName</key>
<string>SincApp</string>
<key>LSItemContentTypes</key>
<array>
<string>br.com.xxx.sincapp</string>
</array>
</dict>
</array>
Entitlement.plist like this:
<key>com.apple.security.application-groups</key>
<array>
<string>group.com.xxx.sincapp</string>
</array>

AppDelegate.cs

[Register("AppDelegate")]
public partial class AppDelegate : global::Xamarin.Forms.Platform.iOS.FormsApplicationDelegate
{
//
// This method is invoked when the application has loaded and is ready to run. In this

public override bool HandleOpenURL(UIApplication application, NSUrl url)
{
BindValue(url);
return true;
}
private void BindValue(NSUrl url)
{
if (url.Scheme == "sincapp-scan-back")
{
NSNotificationCenter
.DefaultCenter
.PostNotificationName("EventNotification", null, null);
}
}
public override bool OpenUrl(UIApplication application, NSUrl url, string sourceApplication, NSObject annotation)
{
// We need to handle URLs by passing them to their own OpenUrl in order to make the SSO authentication works.
BindValue(url);
return true;
}
}
public class iOSInitializer : IPlatformInitializer
{
public void RegisterTypes(IContainerRegistry containerRegistry)
{
// Register any platform specific implementations
}
}
}
ScanCameraiOS
private async Task callMainViewController()
{
ScamCameraViewController scvc = new ScamCameraViewController();
scvc.ViewDidLoad();
}
But when I degub it, var isSincAppProcessSuccess is returning always false and isSincAppProcessSuccess2 null.
The same app developed in Swift is working.
Someone could help me, please?
