Crashing at AccountStore.Create ().Save (e.Account, ");

Question

In the Xamarin.Forms example ToDoAwsAuth at

https://developer.xamarin.com/guides/xamarin-forms/web-services/authentication/oauth/

After successful login, in aOnAuthenticationCompleted event, the application is crashing when trying to save to Xamarin.Auth at

AccountStore.Create ().Save (e.Account, "ToDoList");

The error says not able to say to keychain

Looking forward for help.

Hey OP, if you still alive, what is the actual error message? What do you mean by not able to say to keychain. — Mahmoud

See if you have a file called Entitlements.plist if so click on it and check Enable Keychain

or

create a new file names Entitlements.plist with the following content then drag and drop it on your project

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>keychain-access-groups</key>
    <array>
        <string>your bundle id</string>
    </array>
</dict>
</plist>

Right click on your project
Choose Options
Choose iOS Bundle Signing
Choose Entitlements.plist

Thats all then it should be fine !
